The DEFAULT value is ON. FP_FAST_FMAF FP_FAST_FMA FP_FAST_FMA_HALF FP_CONTRACT The FP_CONTRACT pragma takes the form: #pragma OPENCL FP_CONTRACT on-off-switch FP_CONTRACT can be used to allow (if the state is on) or disallow (if the state is off) the implementation to contract expressions. Each pragma can occur either outside external declarations or preceding all explicit declarations and statements inside a compound statement. The parameter on-off-switch is one of ON, OFF or DEFAULT. The DEFAULT value is ON. When outside external declarations, the pragma takes effect from its occurrence until another FP_CONTRACT pragma is encountered, or until the end of the translation unit. When inside a compound statement, the pragma takes effect from its occurrence until another FP_CONTRACT pragma is encountered (including within a nested compound statement), or until the end of the compound statement; at the end of a compound statement the state for the pragma is restored to its condition just before the compound statement. If this pragma is used in any other context, the behavior is undefined. FP_FAST_FMAF and FP_FAST_FMA The FP_FAST_FMAF macro indicates whether the fma function is fast compared with direct code for single precision floating-point. If defined, the FP_FAST_FMAF macro shall indicate that the fma() function generally executes about as fast as, or faster than, a multiply and an add of float operands. The FP_FAST_FMA macro indicates whether the fma family of functions are fast compared with direct code for double precision floating-point. If defined, the FP_FAST_FMA macro shall indicate that the fma() function generally executes about as fast as, or faster than, a multiply and an add of double operands. The FP_FAST_FMA_HALF macro indicates whether the fma() family of functions are fast compared with direct code for half precision floating-point.

The binaries are loaded for devices specified in this list. num_devices The number of devices listed in device_list. The devices associated with the program object will be the list of devices specified by device_list. The list of devices specified by device_list must be devices associated with context. lengths An array of the size in bytes of the program binaries to be loaded for devices specified by device_list. binaries An array of pointers to program binaries to be loaded for devices specified by device_list. For each device given by device_list[i], the pointer to the program binary for that device is given by binaries[i] and the length of this corresponding binary is given by lengths[i]. lengths[i] cannot be zero and binaries[i] cannot be a NULL pointer. The program binaries specified by binaries contain the bits that describe one of the following: a program executable to be run on the device(s) associated with context. a compiled program for device(s) associated with context. a library of compiled programs for device(s) associated with context. The program binary can consist of either or both of device-specific code and/or implementation-specific intermediate representation (IR) which will be converted to the device-specific code. binary_status Returns whether the program binary for each device specified in device_list was loaded successfully or not. It is an array of num_devices entries and returns CL_SUCCESS in binary_status[i] if binary was successfully loaded for device specified by device_list[i]; otherwise returns CL_INVALID_VALUE if lengths[i] is zero or if binaries[i] is a NULL value or CL_INVALID_BINARY in binary_status[i] if program binary is not a valid binary for the specified device. If binary_status is NULL, it is ignored. errcode_ret Returns an appropriate error code. If errcode_ret is NULL, no error code is returned. Notes OpenCL allows applications to create a program object using the program source or binary and build appropriate program executables. This can be very useful as it allows applications to load program source and then compile and link to generate a program executable online on its first instance for appropriate OpenCL devices in the system. These executables can now be queried and cached by the application. Future instances of the application launching will no longer need to compile and link the program executables. The cached executables can be read and loaded by the application, which can help significantly reduce the application initialization time.

The goal of this extension is to provide interoperability between OpenCL and Direct3D 10. This is designed to function analogously to the OpenGL interoperability. If this extension is supported by an implementation, the string "cl_khr_d3d10_sharing" will be present in the CL_PLATFORM_EXTENSIONS or CL_DEVICE_EXTENSIONS string described in the table of allowed values for param_name for clGetDeviceInfo. As currently proposed, the interfaces for this extension would be provided in cl_d3d10.h. This section discusses OpenCL functions that allow applications to use Direct3D 10 resources as OpenCL memory objects. This allows efficient sharing of data between OpenCL and Direct3D 10. The OpenCL API may be used to execute kernels that read and/or write memory objects that are also Direct3D 10 resources. An OpenCL image object may be created from a Direct3D 10 texture resource. An OpenCL buffer object may be created from a Direct3D 10 buffer resource. OpenCL memory objects may be created from Direct3D 10 objects if and only if the OpenCL context has been created from a Direct3D 10 device. Lifetime of Shared Objects An OpenCL memory object created from a Direct3D 10 resource remains valid as long as the corresponding Direct3D 10 resource has not been deleted. If the Direct3D 10 resource is deleted through the Direct3D 10 API, subsequent use of the OpenCL memory object will result in undefined behavior, including but not limited to possible OpenCL errors, data corruption, and program termination. The successful creation of a cl_context against a Direct3D 10 device specified via the context create parameter CL_CONTEXT_D3D10_DEVICE_KHR will increment the internal Direct3D reference count on the specified Direct3D 10 device. The internal Direct3D reference count on that Direct3D 10 device will be decremented when the OpenCL reference count on the returned OpenCL context drops to zero. The OpenCL context and corresponding command-queues are dependent on the existence of the Direct3D 10 device from which the OpenCL context was created. If the Direct3D 10 device is deleted through the Direct3D 10 API, subsequent use of the OpenCL context will result in undefined behavior, including but not limited to possible OpenCL errors, data corruption, and program termination. khronos-opencl-man-1.0~svn22836/mathFunctions.xml0000644000175000017500000003243711660441607021652 0ustar mathieumathieu ]> Math Built-In Functions Math Built-In Functions 2007-2011 The Khronos Group Inc.

things: # 1. First, the xsltproc program transforms .xml into HTML format. # 2. Next, a certain string regarding "xml-stylesheet" is replaced. We # don't know why, but that's how the OpenGL build tools worked, so we # follow the same convention for OpenCL. # 2a. Replace all occurrences of 'fsfunc' with # ''. This works around a bug in the # docbook-xsl 1.76.1 stylesheets. More recent stylesheet releases # don't have this bug, but they aren't installed everywhere. See # http://sourceforge.net/tracker/?func=detail&aid=3481384&group_id=21935&atid=373747 # 3. Then we replace all occurrences of 'target="_top"' with # 'target="pagedisplay" so that linked pages will open in the same # frame. We couldn't figure out how to modify the Docbook rules to # change the target attribute, so we just do it here. # 4. Finally, we replace a particular string regarding # "xhtml1-transitional.dtd", again based on the OpenGL build. This # is so that references to the DTD don't cause spurious hits on # the W3C web server (IE does this, although it doesn't need to). %.html: ../%.xml $(DB2XHTML) $(ADDTL_DEPS) $(XSLT) --xinclude -o

pageNumberLookup.rb filename.html > outputFile.html # # This script is used to replace symbolic references to locations in the OpenCL # specification with page number references. This can be used when you want the # reference page to refer to section XYZ of the OpenCL spec with a link and have # the link open the spec document to section XYZ. This approach is based on the # "named destination" feature for PDF files. # # Ideally we wanted to link to the named destinations, but inconsistencies between # versions of MS Word and other limitations prevent us from doing that at this time. # So, this is a second-best solution in which we map symbolic names to page # numbers, then the link will open the spec to the specified page. To use this # solution, refer to a section in the spec using a symbolic name that you make up # in a element with a uri attribute that is the symbolic name. Then add # the keyword to the lookup table below with the corresponding page number from # the Spec. # # For example to link to the spec section for gl_sharing, use: # # OpenCL Specification # # The xsltproc program generates a temporary HTML file where the XML line above # is transformed into a line containing a placeholder URL: # # # OpenCL Specification # # When this lookup program is run on the temporary HTML file, it will look up the # keyword and replace the placeholder text in the HTML file with the final URL. # The final URL is specified below in Specnames. This transforms the placeholder # line into the final form, in this manner: # # # OpenCL Specification # # (You can control what the first part of the URL is by modifying the SpecBaseUrl # variable in the opencl-man.xsl file.) # Here are the real spec filenames of the OpenCL 1.2 spec documents (see comments above): Core = "opencl-1.2.pdf" Ext = "opencl-1.2-extensions.pdf" ############################################################################### # Spec page number mapping here. First string in quotes.

The list of supported param_name types and the information returned in param_value by clGetProgramInfo is described in the table below. cl_program_info Return Type and Info. returned in param_value CL_PROGRAM_REFERENCE_COUNT Return type: cl_uint Return the program reference count. The reference count returned should be considered immediately stale. It is unsuitable for general use in applications. This feature is provided for identifying memory leaks. CL_PROGRAM_CONTEXT Return type: cl_context Return the context specified when the program object is created CL_PROGRAM_NUM_DEVICES Return type: cl_uint Return the number of devices associated with program. CL_PROGRAM_DEVICES Return type: cl_device_id[] Return the list of devices associated with the program object. This can be the devices associated with context on which the program object has been created or can be a subset of devices that are specified when a progam object is created using clCreateProgramWithBinary. CL_PROGRAM_SOURCE Return type: char[] Return the program source code specified by clCreateProgramWithSource. The source string returned is a concatenation of all source strings specified to clCreateProgramWithSource with a null terminator. The concatenation strips any nulls in the original source strings. If program is created using clCreateProgramWithBinary or clCreateProgramWithBuiltInKernels, a null string or the appropriate program source code is returned depending on whether or not the program source code is stored in the binary. The actual number of characters that represents the program source code including the null terminator is returned in param_value_size_ret. CL_PROGRAM_BINARY_SIZES Return type: size_t[] Returns an array that contains the size in bytes of the program binary (could be an executable binary, compiled binary or library binary) for each device associated with program. The size of the array is the number of devices associated with program. If a binary is not available for a device(s), a size of zero is returned. If program is created using clCreateProgramWithBuiltInKernels, the implementation may return zero in any entries of the returned array. CL_PROGRAM_BINARIES Return type: unsigned char *[] Return the program binaries (could be an executable binary, compiled binary or library binary) for all devices associated with program. For each device in program, the binary returned can be the binary specified for the device when program is created with clCreateProgramWithBinary or it can be the executable binary generated by clBuildProgram or clLinkProgram. If program is created with clCreateProgramWithSource, the binary returned is the binary generated by clBuildProgram, clCompileProgram, or clLinkProgram. The bits returned can be an implementation-specific intermediate representation (a.k.a. IR) or device specific executable bits or both. The decision on which information is returned in the binary is up to the OpenCL implementation. param_value points to an array of n pointers allocated by the caller, where n is the number of devices associated with program. The buffer sizes needed to allocate the memory that these n pointers refer to can be queried using the CL_PROGRAM_BINARY_SIZES query as described in this table. Each entry in this array is used by the implementation as the location in memory where to copy the program binary for a specific device, if there is a binary available. To find out which device the program binary in the array refers to, use the CL_PROGRAM_DEVICES query to get the list of devices. There is a one-to-one correspondence between the array of n pointers returned by CL_PROGRAM_BINARIES and array of devices returned by CL_PROGRAM_DEVICES. If an entry value in the array is NULL, the implementation skips copying the program binary for the specific device identified by the array index. CL_PROGRAM_NUM_KERNELS Return type: size_t Returns the number of kernels declared in program that can be created with clCreateKernel. This information is only available after a successful program executable has been built for at least one device in the list of devices associated with program. CL_PROGRAM_KERNEL_NAMES Return type: char[] Returns a semi-colon separated list of kernel names in program that can be created with clCreateKernel. This information is only available after a successful program executable has been built for at least one device in the list of devices associated with program. param_value A pointer to memory where the appropriate result being queried is returned. If param_value is NULL, it is ignored. param_value_size Used to specify the size in bytes of memory pointed to by param_value. This size must be ≥ size of return type as described in the table above. param_value_size_ret Returns the actual size in bytes of data copied to param_value. If param_value_size_ret is NULL, it is ignored. Errors Returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors: CL_INVALID_VALUE if param_name is not valid, or if size in bytes specified by param_value_size is < size of return type as described in the table above and param_value is not NULL. CL_INVALID_PROGRAM if program is not a valid program object. CL_INVALID_PROGRAM_EXECUTABLE if param_name is CL_PROGRAM_NUM_KERNELS or CL_PROGRAM_KERNEL_NAMES and a successful program executable has not been built for at least one device in the list of devices associated with program. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

If device_list is a NULL value, the link is performed for all devices associated with context for which a compiled object is available. If device_list is a non-NULL value, the compile is performed for devices specified in this list for which a source has been loaded. num_devices The number of devices listed in device_list. options A pointer to a null-terminated string of characters that describes the link options to be used for building the program executable. See clBuildProgram for a list of supported compiler and linker options. num_input_programs Specifies the number of programs in array referenced by input_programs. input_programs An array of program objects that are compiled binaries or libraries that are to be linked to create the program executable. For each device in device_list or if device_list is NULL the list of devices associated with context, the following cases occur: All programs specified by input_programs contain a compiled binary or library for the device. In this case, a link is performed to generate a program executable for this device. None of the programs contain a compiled binary or library for that device. In this case, no link is performed and there will be no program executable generated for this device. All other cases will return a CL_INVALID_OPERATION error. pfn_notify A function pointer to a notification routine. The notification routine is a callback function that an application can register and which will be called when the program executable has been built (successfully or unsuccessfully). If pfn_notify is not NULL, clLinkProgram does not need to wait for the linker to complete and can return immediately once the linking operation can begin. Once the linker has completed, the pfn_notify callback function is called which returns the program object returned by clLinkProgram. The application can query the link status and log for this program object. This callback function may be called asynchronously by the OpenCL implementation. It is the application’s responsibility to ensure that the callback function is thread-safe. If pfn_notify is NULL, clLinkProgram does not return until the linker has completed. user_data Will be passed as an argument when pfn_notify is called. user_data can be NULL. Notes clLinkProgram creates a new program object which contains this executable. The executable binary can be queried using clGetProgramInfo(program, CL_PROGRAM_BINARIES, ...) and can be specified to clCreateProgramWithBinary to create a new program object. The devices associated with the returned program object will be the list of devices specified by device_list or if device_list is NULL it will be the list of devices associated with context. The linking operation can begin if the context, list of devices, input programs and linker options specified are all valid and appropriate host and device resources needed to perform the link are available. If the linking operation can begin, clLinkProgram returns a valid non-zero program object. Errors If pfn_notify is NULL, the errcode_ret will be set to CL_SUCCESS if the link operation was successful and CL_LINK_FAILURE if there is a failure to link the compiled binaries and/or libraries. If pfn_notify is not NULL, clLinkProgram does not have to wait until the linker to complete and can return CL_SUCCESS in errcode_ret if the linking operation can begin. The pfn_notify callback function will return a CL_SUCCESS or CL_LINK_FAILURE if the linking operation was successful or not. Otherwise clLinkProgram returns a NULL program object with an appropriate error in errcode_ret. The application should query the linker status of this program object to check if the link was successful or not. The list of errors that can be returned are: CL_INVALID_CONTEXT if context is not a valid context. CL_INVALID_VALUE if device_list is NULL and num_devices is greater than zero, or if device_list is not NULL and num_devices is zero. CL_INVALID_VALUE if num_input_programs is zero and input_programs is NULL or if num_input_programs is zero and input_programs is not NULL or if num_input_programs is not zero and input_programs is NULL. CL_INVALID_PROGRAM if programs specified in input_programs are not valid program objects. CL_INVALID_VALUE if pfn_notify is NULL but user_data is not NULL. CL_INVALID_DEVICE if OpenCL devices listed in device_list are not in the list of devices associated with context. CL_INVALID_LINKER_OPTIONS if the linker options specified by options are invalid CL_INVALID_OPERATION if the compilation or build of a program executable for any of the devices listed in device_list by a previous call to clCompileProgram or clBuildProgram for program has not completed. CL_INVALID_OPERATION if the rules for devices containing compiled binaries or libraries as described in input_programs argument above are not followed. CL_LINKER_NOT_AVAILABLE if a linker is not available i.e. CL_DEVICE_LINKER_AVAILABLE specified in the table of allowed values for param_name for clGetDeviceInfo is set to CL_FALSE. CL_LINK_PROGRAM_FAILURE if there is a failure to link the compiled binaries and/or libraries. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

If blocking_write is CL_TRUE the OpenCL implementation copies the data referred to by ptr and enqueues the write command in the command-queue. The memory pointed to by ptr can be reused by the application after the clEnqueueWriteImage call returns. If blocking_write is CL_FALSE the OpenCL implementation will use ptr to perform a nonblocking write. As the write is non-blocking the implementation can return immediately. The memory pointed to by ptr cannot be reused by the application after the call returns. The event argument returns an event object which can be used to query the execution status of the write command. When the write command has completed, the memory pointed to by ptr can then be reused by the application. origin Defines the (x, y, z) offset in pixels in the 1D, 2D, or 3D image, the (x, y) offset and the image index in the image array or the (x) offset and the image index in the 1D image array. If image is a 2D image object, origin[2] must be 0. If image is a 1D image or 1D image buffer object, origin[1] and origin[2] must be 0. If image is a 1D image array object, origin[2] must be 0. If image is a 1D image array object, origin[1] describes the image index in the 1D image array. If image is a 2D image array object, origin[2] describes the image index in the 2D image array. region Defines the (width, height, depth) in pixels of the 1D, 2D or 3D rectangle, the (width, height) in pixels of the 2D rectangle and the number of images of a 2D image array or the (width) in pixels of the 1D rectangle and the number of images of a 1D image array. If image is a 2D image object, region[2] must be 1. If image is a 1D image or 1D image buffer object, region[1] and region[2] must be 1. If image is a 1D image array object, region[2] must be 1. input_row_pitch The length of each row in bytes. This value must be greater than or equal to the element size in bytes * width. If row_pitch is set to 0, the appropriate row pitch is calculated based on the size of each element in bytes multiplied by width. input_slice_pitch Size in bytes of the 2D slice of the 3D region of a 3D image or each image of a 1D or 2D image array being written. This must be 0 if image is a 1D or 2D image. This value must be greater than or equal to row_pitch * height. If slice_pitch is set to 0, the appropriate slice pitch is calculated based on the row_pitch * height. ptr The pointer to a buffer in host memory where image data is to be written to. event_wait_list , num_events_in_wait_list Specify events that need to complete before this particular command can be executed. If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. event Returns an event object that identifies this particular write command and can be used to query or queue a wait for this particular command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. Notes Calling clEnqueueWriteImage to update the latest bits in a region of the image with the ptr argument value set to host_ptr + (origin[2] * image slice pitch + origin[1] * image row pitch + origin[0] * bytes per pixel), where host_ptr is a pointer to the memory region specified when the image being written is created with CL_MEM_USE_HOST_PTR, must meet the following requirements in order to avoid undefined behavior: The host memory region being written contains the latest bits when the enqueued write command begins execution. The input_row_pitch and input_slice_pitch argument values in clEnqueueWriteImage must be set to the image row pitch and slice pitch. The image object is not mapped. The image object is not used by any command-queue until the write command has finished execution. Errors clEnqueueWriteImage return CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors: CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_CONTEXT if the context associated with command_queue and image are not the same or if the context associated with command_queue and events in event_wait_list are not the same. CL_INVALID_MEM_OBJECT if image is not a valid image object. CL_INVALID_VALUE if the region being written specified by origin and region is out of bounds or if ptr is a NULL value. CL_INVALID_VALUE if values in origin and region do not follow rules described in the argument description for origin and region. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list > 0, or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects in event_wait_list are not valid events. CL_INVALID_IMAGE_SIZE if image dimensions (image width, height, specified or compute row and/or slice pitch) for image are not supported by device associated with queue. CL_INVALID_IMAGE_FORMAT if image format (image channel order and data type) for image are not supported by device associated with queue. CL_MEM_OBJECT_ALLOCATION_FAILURE if there is a failure to allocate memory for data store associated with image. CL_INVALID_OPERATION if the device associated with command_queue does not support images (i.e. CL_DEVICE_IMAGE_SUPPORT specified the table of allowed values for param_name for clGetDeviceInfo is CL_FALSE). CL_INVALID_OPERATION if clEnqueueWriteImage is called on image which has been created with CL_MEM_HOST_WRITE_ONLY or CL_MEM_HOST_NO_ACCESS. CL_EXEC_STATUS_ERROR_FOR_EVENTS_IN_WAIT_LIST if the write operations are blocking and the execution status of any of the events in event_wait_list is a negative integer value. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

Compute (old == cmp) ? val : old and store result at location pointed by p. The function returns old. An application that wants to use this extension will need to include the #pragma OPENCL EXTENSION cl_khr_int64_base_atomics : enable in the OpenCL program source. This function is performed in one atomic transaction. These transactions are atomic for the device executing these atomic functions. There is no guarantee of atomicity if the atomic operations to the same memory location are being performed by kernels executing on multiple devices.

Refer to the table for clCreateBuffer for a description of flags. Only the values CL_MEM_READ_ONLY, CL_MEM_WRITE_ONLY and CL_MEM_READ_WRITE can be used. texture_target texture_target This value must be one of GL_TEXTURE_1D, GL_TEXTURE_1D_ARRAY, GL_TEXTURE_BUFFER, GL_TEXTURE_2D, GL_TEXTURE_2D_ARRAY, GL_TEXTURE_3D, GL_TEXTURE_CUBE_MAP_POSITIVE_X, GL_TEXTURE_CUBE_MAP_POSITIVE_Y, GL_TEXTURE_CUBE_MAP_POSITIVE_Z, GL_TEXTURE_CUBE_MAP_NEGATIVE_X, GL_TEXTURE_CUBE_MAP_NEGATIVE_Y, GL_TEXTURE_CUBE_MAP_NEGATIVE_Z, or GL_TEXTURE_RECTANGLE. This requires OpenGL 3.1. Alternatively, GL_TEXTURE_RECTANGLE_ARB may be specified if the OpenGL extension GL_ARB_texture_rectangle is supported. texture_target is used only to define the image type of texture. No reference to a bound GL texture object is made or implied by this parameter. miplevel The mipmap level to be used. If texture_target is GL_TEXTURE_BUFFER, miplevel must be 0. Implementations may return CL_INVALID_OPERATION for miplevel values > 0 texture The name of a GL 1D, 2D, 3D, 1D array, 2D array, cubemap, rectangle or buffer texture object. The texture object must be a complete texture as per OpenGL rules on texture completeness. The texture format and dimensions defined by OpenGL for the specified miplevel of the texture will be used to create the OpenCL image memory object. Only GL texture objects with an internal format that maps to appropriate image channel order and data type specified in tables 5.5 and 5.6 may be used to create the OpenCL image memory object. errcode_ret Returns an appropriate error code as described below. If errcode_ret is NULL, no error code is returned. Notes If the state of a GL texture object is modified through the GL API (e.g. glTexImage2D, glTexImage3D or the values of the texture parameters GL_TEXTURE_BASE_LEVEL or GL_TEXTURE_MAX_LEVEL are modified) while there exists a corresponding CL image object, subsequent use of the CL image object will result in undefined behavior. The clRetainMemObject and clReleaseMemObject functions can be used to retain and release the image objects. Errors Returns a valid non-zero OpenCL image object and errcode_ret is set to CL_SUCCESS if the image object is created successfully. Otherwise, it returns a NULL value with one of the following error values returned in errcode_ret: CL_INVALID_CONTEXT if context is not a valid context or was not created from a GL context. CL_INVALID_VALUE if values specified in flags are not valid or if value specified in texture_target is not one of the values specified in the description of texture_target. CL_INVALID_MIP_LEVEL if miplevel is less than the value of levelbase (for OpenGL implementations) or zero (for OpenGL ES implementations); or greater than the value of q (for both OpenGL and OpenGL ES). levelbase and q are defined for the texture in section 3.8.10 (Texture Completeness) of the OpenGL 2.1 specification and section 3.7.10 of the OpenGL ES 2.0. CL_INVALID_MIP_LEVEL if miplevel is greater than zero and the OpenGL implementation does not support creating from non-zero mipmap levels. CL_INVALID_GL_OBJECT if texture is not a GL texture object whose type matches texture_target, if the specified miplevel of texture is not defined, or if the width or height of the specified miplevel is zero. CL_INVALID_IMAGE_FORMAT_DESCRIPTOR if the OpenGL texture internal format does not map to a supported OpenCL image format. CL_INVALID_OPERATION if texture is a GL texture object created with a border width value greater than zero. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

For the forms that take an image2d_array_t, Use coord.xy to do an element lookup in the 2D image identified by coord.z in the 2D image array specified by image. The samplerless read image functions behave exactly as the corresponding read image functions that take integer coordinates and a sampler with filter mode set to CLK_FILTER_NEAREST, normalized coordinates set to CLK_NORMALIZED_COORDS_FALSE and addressing mode to CLK_ADDRESS_NONE. read_imageh returns half floating-point values in the range [0.0... 1.0] for image objects created with image_channel_data_type set to one of the predefined packed formats or CL_UNORM_INT8 or CL_UNORM_INT16. read_imageh returns half floating-point values in the range [-1.0... 1.0] for image objects created with image_channel_data_type set to CL_SNORM_INT8, or CL_SNORM_INT16. read_imageh returns half floating-point values for image objects created with image_channel_data_type set to CL_HALF_FLOAT. The read_imageh calls that take integer coordinates must use a sampler with filter mode set to CLK_FILTER_NEAREST, normalized coordinates set to CLK_NORMALIZED_COORDS_FALSE and addressing mode set to CLK_ADDRESS_CLAMP_TO_EDGE, CLK_ADDRESS_CLAMP or CLK_ADDRESS_NONE; otherwise the values returned are undefined.

For all image types except CL_MEM_OBJECT_IMAGE1D_BUFFER, if value specified for flags is 0, the default is used which is CL_MEM_READ_WRITE. For CL_MEM_OBJECT_IMAGE1D_BUFFER image type, if the CL_MEM_READ_WRITE, CL_MEM_READ_ONLY or CL_MEM_WRITE_ONLY values are not specified in flags, they are inherited from the corresponding memory access qualifers associated with buffer. The CL_MEM_USE_HOST_PTR, CL_MEM_ALLOC_HOST_PTR and CL_MEM_COPY_HOST_PTR values cannot be specified in flags but are inherited from the corresponding memory access qualifiers associated with buffer. If CL_MEM_COPY_HOST_PTR is specified in the memory access qualifier values associated with buffer it does not imply any additional copies when the sub-buffer is created from buffer. If the CL_MEM_HOST_WRITE_ONLY, CL_MEM_HOST_READ_ONLY or CL_MEM_HOST_NO_ACCESS values are not specified in flags, they are inherited from the corresponding memory access qualifiers associated with buffer. &clCreate_memflagsInc; image_format A pointer to a structure that describes format properties of the image to be allocated. See cl_image_format for a detailed description of the image format descriptor. image_desc A pointer to a structure that describes type and dimensions of the image to be allocated. See imageDescriptor for more information. host_ptr A pointer to the image data that may already be allocated by the application.

Each 2D image is a linear sequence of adjacent scanlines. Each scanline is a linear sequence of image elements. For a 2D image, the image data specified by host_ptr is stored as a linear sequence of adjacent scanlines. Each scanline is a linear sequence of image elements. For a 1D image array, the image data specified by host_ptr is stored as a linear sequence of adjacent 1D images respectively. Each 1D image or 1D image buffer is a single scanline which is a linear sequence of adjacent elements. errcode_ret Will return an appropriate error code. If errcode_ret is NULL, no error code is returned. Errors clCreateImage returns a valid non-zero image object and errcode_ret is set to CL_SUCCESS if the image object is created successfully. Otherwise, it returns a NULL value with one of the following error values returned in errcode_ret: CL_INVALID_CONTEXT if context is not a valid context. CL_INVALID_VALUE if values specified in flags are not valid. CL_INVALID_IMAGE_FORMAT_DESCRIPTOR if values specified in image_format are not valid or if image_format is NULL. CL_INVALID_IMAGE_DESCRIPTOR if values specified in image_desc are not valid or if image_desc is NULL.

This is the default. CL_MEM_WRITE_ONLY This flags specifies that the memory object will be written but not read by a kernel. Reading from a buffer or image object created with CL_MEM_WRITE_ONLY inside a kernel is undefined. CL_MEM_READ_WRITE and CL_MEM_WRITE_ONLY are mutually exclusive. CL_MEM_READ_ONLY This flag specifies that the memory object is a read-only memory object when used inside a kernel. Writing to a buffer or image object created with CL_MEM_READ_ONLY inside a kernel is undefined. CL_MEM_READ_WRITE or CL_MEM_WRITE_ONLY and CL_MEM_READ_ONLY are mutually exclusive. CL_MEM_USE_HOST_PTR This flag is valid only if host_ptr is not NULL. If specified, it indicates that the application wants the OpenCL implementation to use memory referenced by host_ptr as the storage bits for the memory object. OpenCL implementations are allowed to cache the buffer contents pointed to by host_ptr in device memory. This cached copy can be used when kernels are executed on a device. The result of OpenCL commands that operate on multiple buffer objects created with the same host_ptr or overlapping host regions is considered to be undefined. Refer to the description of the alignment rules for host_ptr for memory objects (buffer and images) created using CL_MEM_USE_HOST_PTR. CL_MEM_ALLOC_HOST_PTR This flag specifies that the application wants the OpenCL implementation to allocate memory from host accessible memory. CL_MEM_ALLOC_HOST_PTR and CL_MEM_USE_HOST_PTR are mutually exclusive. CL_MEM_COPY_HOST_PTR This flag is valid only if host_ptr is not NULL. If specified, it indicates that the application wants the OpenCL implementation to allocate memory for the memory object and copy the data from memory referenced by host_ptr. CL_MEM_COPY_HOST_PTR and CL_MEM_USE_HOST_PTR are mutually exclusive. CL_MEM_COPY_HOST_PTR can be used with CL_MEM_ALLOC_HOST_PTR to initialize the contents of the cl_mem object allocated using host-accessible (e.g. PCIe) memory. CL_MEM_HOST_WRITE_ONLY This flag specifies that the host will only write to the memory object (using OpenCL APIs that enqueue a write or a map for write). This can be used to optimize write access from the host (e.g. enable write combined allocations for memory objects for devices that communicate with the host over a system bus such as PCIe). CL_MEM_HOST_READ_ONLY This flag specifies that the host will only read the memory object (using OpenCL APIs that enqueue a read or a map for read). CL_MEM_HOST_WRITE_ONLY and CL_MEM_HOST_READ_ONLY are mutually exclusive. CL_MEM_HOST_NO_ACCESS This flag specifies that the host will not read or write the memory object. CL_MEM_HOST_WRITE_ONLY or CL_MEM_HOST_READ_ONLY and CL_MEM_HOST_NO_ACCESS are mutually exclusive. khronos-opencl-man-1.0~svn22836/imageMappingInc.xml0000644000175000017500000000637111660441607022056 0ustar mathieumathieu The following table describes the mapping of the number of channels of an image element to the appropriate components in the float4, int4 or uint4 vector data type for the color values returned by read_image{f|i|ui} or supplied to write_image{f|i|ui}. The unmapped components will be set to 0.0 for red, green and blue channels and will be set to 1.0 for the alpha channel. Channel Order float4, int4 or uint4 components of channel data CL_R, CL_Rx (r, 0.0, 0.0, 1.0) CL_A (0.0, 0.0, 0.0, a) CL_RG, CL_RGx (r, g, 0.0, 1.0) CL_RA (r, 0.0, 0.0, a) CL_RGB, CL_RGBx (r, g, b, 1.0) CL_RGBA, CL_BGRA, CL_ARGB (r, g, b, a) CL_INTENSITY (I, I, I, I) CL_LUMINANCE (L, L, L, 1.0) A kernel that uses a sampler with the CL_ADDRESS_CLAMP addressing mode with multiple images may result in additional samplers being used internally by an implementation. If the same sampler is used with multiple images called via read_image{f|i|ui}, then it is possible that an implementation may need to allocate an additional sampler to handle the different border color values that may be needed depending on the image formats being used. These implementation allocated samplers will count against the maximum sampler values supported by the device and given by CL_DEVICE_MAX_SAMPLERS. Enqueuing a kernel that requires more samplers than the implementation can support will result in a CL_OUT_OF_RESOURCES error being returned. khronos-opencl-man-1.0~svn22836/write_mem_fence.xml0000644000175000017500000001057211660441607022154 0ustar mathieumathieu write_mem_fence write_mem_fence 2007-2011 The Khronos Group Inc.

The diagram shows both nodes and edges which are classes and their relationships. As a simplification it shows only classes, and no attributes or operations. As for relationships it shows aggregations (annotated with a solid diamond), associations (no annotation), and inheritance (annotated with an open arrowhead). The cardinality of a relationship is shown on each end of it. A cardinality of "*" represents "many", a cardinality of "1" represents "one and only one" and a cardinality of "0:1" represents "optionally one". The navigability of a relationship is shown using a regular arrowhead. *Unified Modeling Language (http://www.uml.org/) is a trademark of Object Management Group (OMG).

The OpenCL context associated with command_queue and image must be the same. image A valid image object. fill_color The fill color. The fill color is a four component RGBA floating-point color value if the image channel data type is not an unnormalized signed and unsigned integer type, is a four component signed integer value if the image channel data type is an unnormalized signed integer type and is a four component unsigned integer value if the image channel data type is an unormalized unsigned integer type. The fill color will be converted to the appropriate image channel format and order associated with image. origin Defines the (x, y, z) offset in pixels in the 1D, 2D, or 3D image, the (x, y) offset and the image index in the image array or the (x) offset and the image index in the 1D image array. If image is a 2D image object, origin[2] must be 0. If image is a 1D image or 1D image buffer object, origin[1] and origin[2] must be 0. If image is a 1D image array object, origin[2] must be 0. If image is a 1D image array object, origin[1] describes the image index in the 1D image array. If image is a 2D image array object, origin[2] describes the image index in the 2D image array. region Defines the (width, height, depth) in pixels of the 1D, 2D or 3D rectangle, the (width, height) in pixels of the 2D rectangle and the number of images of a 2D image array or the (width) in pixels of the 1D rectangle and the number of images of a 1D image array.

If image is a 1D image array object, region[2] must be 1. event_wait_list , num_events_in_wait_list Specify events that need to complete before this particular command can be executed. If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. event Returns an event object that identifies this particular write command and can be used to query or queue a wait for this particular command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. clEnqueueBarrierWithWaitList can be used instead. If the event_wait_list and the event arguments are not NULL, the event argument should not refer to an element of the event_wait_list array. Notes The usage information which indicates whether the memory object can be read or written by a kernel and/or the host and is given by the cl_mem_flags argument value specified when image is created is ignored by clEnqueueFillImage.

CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_CONTEXT if the context associated with command_queue and image are not the same or if the context associated with command_queue and events in event_wait_list are not the same. CL_INVALID_MEM_OBJECT if image is not a valid image object. CL_INVALID_VALUE if fill_color is NULL. CL_INVALID_VALUE if the region being written specified by origin and region is out of bounds or if ptr is a NULL value.

If device_list is NULL value, the program executable is built for all devices associated with program for which a source or binary has been loaded. If device_list is a non-NULL value, the program executable is built for devices specified in this list for which a source or binary has been loaded. num_devices The number of devices listed in device_list. options A pointer to a null-terminated string of characters that describes the build options to be used for building the program executable. The list of supported options is described below. pfn_notify A function pointer to a notification routine. The notification routine is a callback function that an application can register and which will be called when the program executable has been built (successfully or unsuccessfully). If pfn_notify is not NULL, clBuildProgram does not need to wait for the build to complete and can return immediately once the build operation can begin. The build operation can begin if the context, program whose sources are being compiled and linked, list of devices and build options specified are all valid and appropriate host and device resources needed to perform the build are available. If pfn_notify is NULL, clBuildProgram does not return until the build has completed. This callback function may be called asynchronously by the OpenCL implementation. It is the application’s responsibility to ensure that the callback function is thread-safe. user_data Passed as an argument when pfn_notify is called. user_data can be NULL. Notes Builds (compiles & links) a program executable from the program source or binary for all the devices or a specific device(s) in the OpenCL context associated with program. OpenCL allows program executables to be built using the source or the binary. clBuildProgram must be called for program created using either clCreateProgramWithSource or clCreateProgramWithBinary to build the program executable for one or more devices associated with program. If program is created with clCreateProgramWithBinary, then the program binary must be an executable binary (not a compiled binary or library). The executable binary can be queried using clGetProgramInfo(program, CL_PROGRAM_BINARIES, ...) and can be specified to clCreateProgramWithBinary to create a new program object. &buildOptionsInc; Errors clBuildProgram returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors: CL_INVALID_PROGRAM if program is not a valid program object. CL_INVALID_VALUE if device_list is NULL and num_devices is greater than zero, or if device_list is not NULL and num_devices is zero. CL_INVALID_VALUE if pfn_notify is NULL but user_data is not NULL. CL_INVALID_DEVICE if OpenCL devices listed in device_list are not in the list of devices associated with program. CL_INVALID_BINARY if program is created with clCreateProgramWithBinary and devices listed in device_list do not have a valid program binary loaded. CL_INVALID_BUILD_OPTIONS if the build options specified by options are invalid.

Description The printf built-in function writes output to an implementation-defined stream such as stdout under control of the string pointed to by format that specifies how subsequent arguments are converted for output. If there are insufficient arguments for the format, the behavior is undefined. If the format is exhausted while arguments remain, the excess arguments are evaluated (as always) but are otherwise ignored. The printf function returns when the end of the format string is encountered. Notes printf returns 0 if it was executed successfully and -1 otherwise. printf output synchronization When the event that is associated with a particular kernel invocation is completed, the output of all printf() calls executed by this kernel invocation is flushed to the implementation-defined output stream. Calling clFinish on a command queue flushes all pending output by printf in previously enqueued and completed commands to the implementation-defined output stream. In the case that printf is executed from multiple work-items concurrently, there is no guarantee of ordering with respect to written data. For example, it is valid for the output of a work-item with a global id (0,0,1) to appear intermixed with the output of a work-item with a global id (0,0,4) and so on. printf format string The format shall be a character sequence, beginning and ending in its initial shift state. The format is composed of zero or more directives: ordinary characters (not %), which are copied unchanged to the output stream; and conversion specifications, each of which results in fetching zero or more subsequent arguments, converting them, if applicable, according to the corresponding conversion specifier, and then writing the result to the output stream. As format is in the constant address space it must be resolvable at compile time and thus cannot be dynamically created by the executing program, itself. Each conversion specification is introduced by the character %. After the %, the following appear in sequence: Zero or more flags (in any order) that modify the meaning of the conversion specification. An optional minimum field width. If the converted value has fewer characters than the field width, it is padded with spaces (by default) on the left (or right, if the left adjustment flag, described later, has been given) to the field width. The field width takes the form of a nonnegative decimal integer.) Note that 0 is taken as a flag, not as the beginning of a field width. An optional precision that gives the minimum number of digits to appear for the d, i, o, u, x, and X conversions, the number of digits to appear after the decimal point character for a, A, e, E, f, and F conversions, the maximum number of significant digits for the g and G conversions, or the maximum number of bytes to be written for s conversions. The precision takes the form of a period (.) followed by an optional decimal integer; if only the period is specified, the precision is taken as zero. If a precision appears with any other conversion specifier, the behavior is undefined. An optional vector specifier. A length modifier that specifies the size of the argument. The length modifier is required with a vector specifier and together specifies the vector type. Implicit conversions between vector types are disallowed (as per section 6.2.1). If the vector specifier is not specified, the length modifier is optional. A conversion specifier character that specifies the type of conversion to be applied. The flag characters and their meanings are: - The result of the conversion is left-justified within the field. (It is right-justified if this flag is not specified.) + The result of a signed conversion always begins with a plus or minus sign. (It begins with a sign only when a negative value is converted if this flag is not specified.) The results of all floating conversions of a negative zero, and of negative values that round to zero, include a minus sign. space If the first character of a signed conversion is not a sign, or if a signed conversion results in no characters, a space is prefixed to the result. If the space and + flags both appear, the space flag is ignored. # The result is converted to an "alternative form". For o conversion, it increases the precision, if and only if necessary, to force the first digit of the result to be a zero (if the value and precision are both 0, a single 0 is printed). For x (or X) conversion, a nonzero result has 0x (or 0X) prefixed to it. For a, A, e, E, f, F, g, and G conversions, the result of converting a floating-point number always contains a decimal-point character, even if no digits follow it. (Normally, a decimal-point character appears in the result of these conversions only if a digit follows it.) For g and G conversions, trailing zeros are not removed from the result. For other conversions, the behavior is undefined. 0 For d, i, o, u, x, X, a, A, e, E, f, F, g, and G conversions, leading zeros (following any indication of sign or base) are used to pad to the field width rather than performing space padding, except when converting an infinity or NaN. If the 0 and - flags both appear, the 0 flag is ignored. For d, i, o, u, x, and X conversions, if a precision is specified, the 0 flag is ignored. For other conversions, the behavior is undefined. The vector specifier and its meaning is: vn Specifies that a following a, A, e, E, f, F, g, G, d, i, o, u, x, or X conversion specifier applies to a vector argument, where n is the size of the vector and must be 2, 3, 4, 8 or 16. The vector value is displayed in the following general form: value1 C value2 C ... C valuen where C is a separator character. The value for this separator character is a comma. If the vector specifier is not used, the length modifiers and their meanings are: hh Specifies that a following d, i, o, u, x, or X conversion specifier applies to a char or uchar argument (the argument will have been promoted according to the integer promotions, but its value shall be converted to char or uchar before printing). h Specifies that a following d, i, o, u, x, or X conversion specifier applies to a short or ushort argument (the argument will have been promoted according to the integer promotions, but its value shall be converted to short or unsigned short before printing). l (ell) Specifies that a following d, i, o, u, x, or X conversion specifier applies to a long or ulong argument. The l modifier is supported by the full profile. For the embedded profile, the l modifier is supported only if 64-bit integers are supported by the device. If the vector specifier is used, the length modifiers and their meanings are: hh Specifies that a following d, i, o, u, x, or X conversion specifier applies to a charn or ucharn argument (the argument will not be promoted). h Specifies that a following d, i, o, u, x, or X conversion specifier applies to a shortn or ushortn argument (the argument will not be promoted); that a following a, A, e, E, f, F, g, or G conversion specifier applies to a halfn argument if the cl_khr_fp16 extension is supported. hl This modifier can only be used with the vector specifier. Specifies that a following d, i, o, u, x, or X conversion specifier applies to a intn or uintn argument; that a following a, A, e, E, f, F, g, or G conversion specifier applies to a floatn argument. l (ell) Specifies that a following d, i, o, u, x, or X conversion specifier applies to a longn or ulongn argument; that a following a, A, e, E, f, F, g, or G conversion specifier applies to a doublen argument. The l modifier is supported by the full profile. For the embedded profile, the l modifier is supported only if 64-bit integers or double-precision floating-point are supported by the device. If a vector specifier appears without a length modifier, the behavior is undefined. The vector data type described by the vector specifier and length modifier must match the data type of the argument; otherwise the behavior is undefined. If a length modifier appears with any conversion specifier other than as specified above, the behavior is undefined The conversion specifiers and their meanings are: d,i The int, charn, shortn, intn or longn argument is converted to signed decimal in the style [−]dddd. The precision specifies the minimum number of digits to appear; if the value being converted can be represented in fewer digits, it is expanded with leading zeros. The default precision is 1. The result of converting a zero value with a precision of zero is no characters. o,u,x,X The unsigned int, ucharn, ushortn, uintn or ulongn argument is converted to unsigned octal (o), unsigned decimal (u), or unsigned hexadecimal notation (x or X) in the style dddd; the letters abcdef are used for x conversion and the letters ABCDEF for X conversion. The precision specifies the minimum number of digits to appear; if the value being converted can be represented in fewer digits, it is expanded with leading zeros. The default precision is 1. The result of converting a zero value with a precision of zero is no characters. f,F A double, halfn, floatn or doublen argument representing a floating-point number is converted to decimal notation in the style [−]ddd.ddd, where the number of digits after the decimal-point character is equal to the precision specification. If the precision is missing, it is taken as 6; if the precision is zero and the # flag is not specified, no decimal-point character appears. If a decimal-point character appears, at least one digit appears before it. The value is rounded to the appropriate number of digits. A double, halfn, floatn or doublen argument representing an infinity is converted in one of the styles [-]inf or [-]infinity — which style is implementation-defined. A double, halfn, floatn or doublen argument representing a NaN is converted in one of the styles [- ]nan or [-]nan(n-char-sequence) — which style, and the meaning of any n-charsequence, is implementation-defined. The F conversion specifier produces INF, INFINITY, or NAN instead of inf, infinity, or nan, respectively. When applied to infinite and NaN values, the -, +, and space flag characters have their usual meaning; the # and 0 flag characters have no effect. e,E A double, halfn, floatn or doublen argument representing a floating-point number is converted in the style [−]d.ddd e±dd, where there is one digit (which is nonzero if the argument is nonzero) before the decimal-point character and the number of digits after it is equal to the precision; if the precision is missing, it is taken as 6; if the precision is zero and the # flag is not specified, no decimal-point character appears. The value is rounded to the appropriate number of digits. The E conversion specifier produces a number with E instead of e introducing the exponent. The exponent always contains at least two digits, and only as many more digits as necessary to represent the exponent. If the value is zero, the exponent is zero. A double, halfn, floatn or doublen argument representing an infinity or NaN is converted in the style of an f or F conversion specifier g,G A double, halfn, floatn or doublen argument representing a floating-point number is converted in style f or e (or in style F or E in the case of a G conversion specifier), depending on the value converted and the precision. Let P equal the precision if nonzero, 6 if the precision is omitted, or 1 if the precision is zero. Then, if a conversion with style E would have an exponent of X: — if P > X ≥ −4, the conversion is with style f (or F) and precision P − (X + 1). — otherwise, the conversion is with style e (or E) and precision P − 1. Finally, unless the # flag is used, any trailing zeros are removed from the fractional portion of the result and the decimal-point character is removed if there is no fractional portion remaining. A double, halfn, floatn or doublen e argument representing an infinity or NaN is converted in the style of an f or F conversion specifier. a,A A double, halfn, floatn or doublen argument representing a floating-point number is converted in the style [−]0xh.hhhh p±d, where there is one hexadecimal digit (which is nonzero if the argument is a normalized floating-point number and is otherwise unspecified) before the decimal-point character) and the number of hexadecimal digits after it is equal to the precision; if the precision is missing, then the precision is sufficient for an exact representation of the value; if the precision is zero and the # flag is not specified, no decimal point character appears. The letters abcdef are used for a conversion and the letters ABCDEF for A conversion. The A conversion specifier produces a number with X and P instead of x and p. The exponent always contains at least one digit, and only as many more digits as necessary to represent the decimal exponent of 2. If the value is zero, the exponent is zero. A double, halfn, floatn or doublen argument representing an infinity or NaN is converted in the style of an f or F conversion specifier. Binary implementations can choose the hexadecimal digit to the left of the decimal-point character so that subsequent digits align to nibble (4-bit) boundaries. NOTE: The conversion specifiers e,E,g,G,a,A convert a float or half argument that is a scalar type to a double only if the double data type is supported. If the double data type is not supported, the argument will be a float instead of a double and the half type will be converted to a float. c The int argument is converted to an unsigned char, and the resulting character is written. s The argument shall be a literal string. No special provisions are made for multibyte characters. The behavior of printf with the s conversion specifier is undefined if the argument value is not a pointer to a literal string. Characters from the literal string array are written up to (but not including) the terminating null character. If the precision is specified, no more than that many bytes are written. If the precision is not specified or is greater than the size of the array, the array shall contain a null character. p The argument shall be a pointer to void. The pointer can refer to a memory region in the global, constant, local or private address space. The value of the pointer is converted to a sequence of printing characters in an implementation-defined manner. % A % character is written. No argument is converted. The complete conversion specification shall be %%. If a conversion specification is invalid, the behavior is undefined. If any argument is not the correct type for the corresponding conversion specification, the behavior is undefined. In no case does a nonexistent or small field width cause truncation of a field; if the result of a conversion is wider than the field width, the field is expanded to contain the conversion result. For a and A conversions, the value is correctly rounded to a hexadecimal floating number with the given precision. Differences between OpenCL C and C99 printf The l modifier followed by a c conversion specifier or s conversion specifier is not supported by OpenCL C. The ll, j, z, t, and L length modifiers are not supported by OpenCL C. The n conversion specifier is not supported by OpenCL C but is reserved. OpenCL C adds the optional vn vector specifier to support printing of vector types. The conversion specifiers f, F, e, E, g, G, a, A convert a float argument to a double only if the double data type is supported. Refer to the description of CL_DEVICE_DOUBLE_FP_CONFIG. If the double data type is not supported, the argument will be a float instead of a double. For the embedded profile, the l length modifier is supported only if 64-bit integers are supported. In OpenCL C, printf returns 0 if it was executed successfully and -1 otherwise vs. C99 where printf returns the number of characters printed or a negative value if an output or encoding error occurred. In OpenCL C, the conversion specifier s can only be used for arguments that are literal strings. Examples float4 f = (float4)(1.0f, 2.0f, 3.0f, 4.0f); uchar4 uc = (uchar4)(0xFA, 0xFB, 0xFC, 0xFD); printf("f4 = %2.2v4hlf\n", f); printf("uc = %#v4hhx\n", uc); // The above two calls print the following: f4 = 1.00,2.00,3.00,4.00 uc = 0xfa,0xfb,0xfc,0xfd A few examples of valid use cases of printf for the conversion specifier s are given below. The argument value must be a pointer to a literal string. kernel void my_kernel( ... ) { printf("%s\n", "this is a test string\n"); } A few examples of invalid use cases of printf for the conversion specifier s are given below: kernel void my_kernel(global char *s, ... ) { printf("%s\n", s); constant char *p = "this is a test string\n"; printf("%s\n", p); printf("%s\n", &p[3]); } A few examples of invalid use cases of printf where data types given by the vector specifier and length modifier do not match the argument type are given below: kernel void my_kernel(global char *s, … ) { uint2 ui = (uint2)(0x12345678, 0x87654321); printf("unsigned short value = (%#v2hx)\n", ui) printf("unsigned char value = (%#v2hhx)\n", ui) } Specification OpenCL Specification khronos-opencl-man-1.0~svn22836/cl_image_format.xml0000644000175000017500000003151011660441607022127 0ustar mathieumathieu cl_image_format cl_image_format 2007-2010 The Khronos Group Inc.

Valid values are described in the table below. Format Description CL_R, CL_Rx, or CL_A CL_INTENSITY This format can only be used if channel data type = CL_UNORM_INT8, CL_UNORM_INT16, CL_SNORM_INT8, CL_SNORM_INT16, CL_HALF_FLOAT, or CL_FLOAT. CL_LUMINANCE This format can only be used if channel data type = CL_UNORM_INT8, CL_UNORM_INT16, CL_SNORM_INT8, CL_SNORM_INT16, CL_HALF_FLOAT, or CL_FLOAT. CL_RG, CL_RGx, or CL_RA CL_RGB or CL_RGBx This format can only be used if channel data type = CL_UNORM_SHORT_565, CL_UNORM_SHORT_555 or CL_UNORM_INT101010. CL_RGBA CL_ARGB, CL_BGRA. This format can only be used if channel data type = CL_UNORM_INT8, CL_SNORM_INT8, CL_SIGNED_INT8 or CL_UNSIGNED_INT8. image_channel_data_type Describes the size of the channel data type. The number of bits per element determined by the image_channel_data_type and image_channel_order must be a power of two. The list of supported values is described in the table below. Image Channel Data Type Description CL_SNORM_INT8 Each channel component is a normalized signed 8-bit integer value. CL_SNORM_INT16 Each channel component is a normalized signed 16-bit integer value. CL_UNORM_INT8 Each channel component is a normalized unsigned 8-bit integer value. CL_UNORM_INT16 Each channel component is a normalized unsigned 16-bit integer value. CL_UNORM_SHORT_565 Represents a normalized 5-6-5 3-channel RGB image. The channel order must be CL_RGB or CL_RGBx. CL_UNORM_SHORT_555 Represents a normalized x-5-5-5 4-channel xRGB image. The channel order must be CL_RGB or CL_RGBx. CL_UNORM_INT_101010 Represents a normalized x-10-10-10 4-channel xRGB image. The channel order must be CL_RGB or CL_RGBx. CL_SIGNED_INT8 Each channel component is an unnormalized signed 8-bit integer value. CL_SIGNED_INT16 Each channel component is an unnormalized signed 16-bit integer value. CL_SIGNED_INT32 Each channel component is an unnormalized signed 32-bit integer value. CL_UNSIGNED_INT8 Each channel component is an unnormalized unsigned 8-bit integer value. CL_UNSIGNED_INT16 Each channel component is an unnormalized unsigned 16-bit integer value. CL_UNSIGNED_INT32 Each channel component is an unnormalized unsigned 32-bit integer value. CL_HALF_FLOAT Each channel component is a 16-bit half-float value. CL_FLOAT Each channel component is a single precision floating-point value. Description For example, to specify a normalized unsigned 8-bit / channel RGBA image: image_channel_order = CL_RGBA image_channel_data_type = CL_UNORM_INT8 image_channel_data_type values of CL_UNORM_SHORT_565, CL_UNORM_SHORT_555 and CL_UNORM_INT_101010 are special cases of packed image formats where the channels of each element are packed into a single unsigned short or unsigned int. For these special packed image formats, the channels are normally packed with the first channel in the most significant bits of the bitfield, and successive channels occupying progressively less significant locations. For CL_UNORM_SHORT_565, R is in bits 15:11, G is in bits 10:5 and B is in bits 4:0. For CL_UNORM_SHORT_555, bit 15 is undefined, R is in bits 14:10, G in bits 9:5 and B in bits 4:0. For CL_UNORM_INT_101010, bits 31:30 are undefined, R is in bits 29:20, G in bits 19:10 and B in bits 9:0. OpenCL implementations must maintain the minimum precision specified by the number of bits in image_channel_data_type. If the image format specified by image_channel_order, and image_channel_data_type cannot be supported by the OpenCL implementation, then the call to clCreateImage will return a NULL memory object.

For the forms that take an image1d_array_t, use coord.x to do an element lookup in the 1D image identified by coord.y in the 1D image array specified by image. The samplerless read image functions behave exactly as the corresponding read image functions that take integer coordinates and a sampler with filter mode set to CLK_FILTER_NEAREST, normalized coordinates set to CLK_NORMALIZED_COORDS_FALSE and addressing mode to CLK_ADDRESS_NONE. read_imagei and read_imageui return unnormalized signed integer and unsigned integer values respectively. Each channel will be stored in a 32-bit integer. read_imagei can only be used with image objects created with image_channel_data_type set to one of the following values: CL_SIGNED_INT8, CL_SIGNED_INT16, or CL_SIGNED_INT32. If the image_channel_data_type is not one of the above values, the values returned by read_imagei are undefined. read_imageui can only be used with image objects created with image_channel_data_type set to one of the following values: CL_UNSIGNED_INT8, CL_UNSIGNED_INT16, and CL_UNSIGNED_INT32. If the image_channel_data_type is not one of the above values, the values returned by read_imageui are undefined. The read_imagei and read_imageui calls support a nearest filter only. The filter_mode specified in sampler must be set to CLK_FILTER_NEAREST; otherwise the values returned are undefined.

The description is per-component. The built-in math functions are not affected by the prevailing rounding mode in the calling environment, and always return the same value as they would if called with the round to nearest even rounding mode. The built-in math functions take scalar or vector arguments. For any specific use of these function, the actual type has to be the same for all arguments and the return type unless otherwise specified. The generic type name gentype is used to indicate that the function can take float, float2, float3, float4, float8, float16, double, double2, double3, double4, double8, or double16 as the type for the arguments. If extended with cl_khr_fp16, generic type name gentype may indicate half and half{2|3|4|8|16} as arguments and return values.

The extension_name will have names of the form cl_khr_<name> for an extension approved by the OpenCL working group and will have names of the form cl_<vendor_name>_<name> for vendor extensions. The token all means that the behavior applies to all extensions supported by the compiler. The table below shows the legal values for extension_name: Extension name Description cl_khr_int64_base_atomics 64-bit integer base atomic operations cl_khr_int64_extended_atomics 64-bit integer extended atomic operations cl_khr_3d_image_writes Writes to 3D image objects cl_khr_fp16 Half-precision floating-point cl_apple_gl_sharing MacOS X OpenGL sharing cl_khr_gl_sharing OpenGL sharing cl_khr_gl_event CL event objects from GL sync objects cl_khr_d3d10_sharing Sharing memory objects wth Direct3D 10 cl_khr_d3d11_sharing Sharing memory objects wth Direct3D 11 cl_khr_dx9_media_sharing Sharing memory objects wth Direct3D 9 cl_khr_icd Access Khronos OpenCL installable client driver loader (ICD Loader. behavior One of the following values: behavior Description enable Behave as specified by the extension extension_name. Report an error on the #pragma OPENCL EXTENSION if the extension_name is not supported, or if all is specified. disable Behave (including issuing errors and warnings) as if the extension extension_name is not part of the language definition. If all is specified, then behavior must revert back to that of the non-extended core version of the language being compiled to. Warn on the #pragma OPENCL EXTENSION if the extension extension_name is not supported. Description The #pragma OPENCL EXTENSION directive is a simple, low-level mechanism to set the behavior for each extension. It does not define policies such as which combinations are appropriate; those must be defined elsewhere. The order of directives matter in setting the behavior for each extension. Directives that occur later override those seen earlier. The all variant sets the behavior for all extensions, overriding all previously issued extension directives, but only if the behavior is set to disable. The initial state of the compiler is as if the directive #pragma OPENCL EXTENSION all : disable was issued, telling the compiler that all error and warning reporting must be done according to this specification, ignoring any extensions. Every extension which affects the OpenCL language semantics, syntax or adds built-in functions to the language must create a preprocessor #define that matches the extension name string. This #define would be available in the language if and only if the extension is supported on a given implementation. Notes This document describes the list of optional features supported by OpenCL 1.2. Optional extensions may be supported by some OpenCL devices. Optional extensions are not required to be supported by a conformant OpenCL implementation, but are expected to be widely available; they define functionality that is likely to move into the required feature set in a future revision of the OpenCL specification OpenCL extensions approved by the OpenCL working group can be promoted to required core features in later revisions of OpenCL. When this occurs, the extension specifications are merged into the core specification. Functions and enumerants that are part of such promoted extensions will have the KHR affix removed. OpenCL implementations of such later revisions must also export the name strings of promoted extensions in the CL_PLATFORM_EXTENSIONS or CL_DEVICE_EXTENSIONS string, and support the KHR-affixed versions of functions and enumerants as a transition aid. Example An extension which adds the extension string "cl_khr_3d_image_writes" should also add a preprocessor #define called cl_khr_3d_image_writes. A kernel can now use this preprocessor #define to do something like the following: #ifdef cl_khr_3d_image_writes // do something using the extension #else // do something else or #error! #endif Specification OpenCL Specification khronos-opencl-man-1.0~svn22836/clGetDeviceIDs.xml0000644000175000017500000003001311660441607021572 0ustar mathieumathieu clGetDeviceIDs clGetDeviceIDs 2007-2011 The Khronos Group Inc.

The device_type can be used to query specific OpenCL devices or all OpenCL devices available. The valid values for device_type are specified in the following table. cl_device_type Description CL_DEVICE_TYPE_CPU An OpenCL device that is the host processor. The host processor runs the OpenCL implementations and is a single or multi-core CPU. CL_DEVICE_TYPE_GPU An OpenCL device that is a GPU. By this we mean that the device can also be used to accelerate a 3D API such as OpenGL or DirectX. CL_DEVICE_TYPE_ACCELERATOR Dedicated OpenCL accelerators (for example the IBM CELL Blade). These devices communicate with the host processor using a peripheral interconnect such as PCIe. CL_DEVICE_TYPE_CUSTOM Dedicated accelerators that do not support programs written in OpenCL C. CL_DEVICE_TYPE_DEFAULT The default OpenCL device in the system. The default device cannot be a CL_DEVICE_TYPE_CUSTOM device. CL_DEVICE_TYPE_ALL All OpenCL devices available in the system except CL_DEVICE_TYPE_CUSTOM devices. num_entries The number of cl_device_id entries that can be added to devices. If devices is not NULL, the num_entries must be greater than zero. devices A list of OpenCL devices found. The cl_device_id values returned in devices can be used to identify a specific OpenCL device. If devices argument is NULL, this argument is ignored. The number of OpenCL devices returned is the mininum of the value specified by num_entries or the number of OpenCL devices whose type matches device_type. num_devices The number of OpenCL devices available that match device_type. If num_devices is NULL, this argument is ignored. Notes clGetDeviceIDs may return all or a subset of the actual physical devices present in the platform and that match device_type. Errors clGetDeviceIDs returns CL_SUCCESS if the function is executed successfully. Otherwise it returns one of the following: CL_INVALID_PLATFORM if platform is not a valid platform. CL_INVALID_DEVICE_TYPE if device_type is not a valid value. CL_INVALID_VALUE if num_entries is equal to zero and devices is not NULL or if both num_devices and devices are NULL. CL_DEVICE_NOT_FOUND if no OpenCL devices that matched device_type were found. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device.

If the CL_MEM_READ_WRITE, CL_MEM_READ_ONLY or CL_MEM_WRITE_ONLY values are not specified in flags, they are inherited from the corresponding memory access qualifers associated with buffer. The CL_MEM_USE_HOST_PTR, CL_MEM_ALLOC_HOST_PTR and CL_MEM_COPY_HOST_PTR values cannot be specified in flags but are inherited from the corresponding memory access qualifiers associated with buffer. If CL_MEM_COPY_HOST_PTR is specified in the memory access qualifier values associated with buffer it does not imply any additional copies when the sub-buffer is created from buffer. If the CL_MEM_HOST_WRITE_ONLY, CL_MEM_HOST_READ_ONLY or CL_MEM_HOST_NO_ACCESS values are not specified in flags, they are inherited from the corresponding memory access qualifiers associated with buffer. &clCreate_memflagsInc; buffer_create_type and buffer_create_info Describes the type of buffer object to be created. The list of supported values for buffer_create_type and corresponding descriptor that buffer_create_info points to is described below. cl_buffer_create_type Description CL_BUFFER_CREATE_TYPE_REGION Create a buffer object that represents a specific region in buffer. buffer_create_info is a pointer to the following structure: typedef struct _cl_buffer_region { size_t origin; size_t size; } cl_buffer_region; (origin, size) defines the offset and size in bytes in buffer. If buffer is created with CL_MEM_USE_HOST_PTR, the host_ptr associated with the buffer object returned is host_ptr + origin. The buffer object returned references the data store allocated for buffer and points to a specific region given by (origin, size) in this data store. CL_INVALID_VALUE is returned in errcode_ret if the region specified by (origin, size) is out of bounds in buffer. CL_INVALID_BUFFER_SIZE if size is 0. CL_MISALIGNED_SUB_BUFFER_OFFSET is returned in errcode_ret if there are no devices in context associated with buffer for which the origin value is aligned to the CL_DEVICE_MEM_BASE_ADDR_ALIGN value. Notes Concurrent reading from, writing to and copying between both a buffer object and its sub-buffer object(s) is undefined. Concurrent reading from, writing to and copying between overlapping sub-buffer objects created with the same buffer object is undefined. Only reading from both a buffer object and its sub-buffer objects or reading from multiple overlapping sub-buffer objects is defined. Errors Returns a valid non-zero buffer object and errcode_ret is set to CL_SUCCESS if the buffer object is created successfully. Otherwise, it returns one of the following error in errcode_ret: CL_INVALID_MEM_OBJECT if buffer is not a valid buffer object or is a sub-buffer object. CL_INVALID_VALUE if buffer was created with CL_MEM_WRITE_ONLY and flags specifies CL_MEM_READ_WRITE or CL_MEM_READ_ONLY, or if buffer was created with CL_MEM_READ_ONLY and flags specifies CL_MEM_READ_WRITE or CL_MEM_WRITE_ONLY, or if flags specifies CL_MEM_USE_HOST_PTR or CL_MEM_ALLOC_HOST_PTR or CL_MEM_COPY_HOST_PTR. CL_INVALID_VALUE if buffer was created with CL_MEM_HOST_WRITE_ONLY and flags specifies CL_MEM_HOST_READ_ONLY or if buffer was created with CL_MEM_HOST_READ_ONLY and flags specifies CL_MEM_HOST_WRITE_ONLY, or if buffer was created with CL_MEM_HOST_NO_ACCESS and flags specifies CL_MEM_HOST_READ_ONLY or CL_MEM_HOST_WRITE_ONLY. CL_INVALID_VALUE if value specified in buffer_create_type is not valid. CL_INVALID_VALUE if value(s) specified in buffer_create_info (for a given buffer_create_type) is not valid or if buffer_create_info is NULL. CL_INVALID_BUFFER_SIZE if size is 0. CL_MEM_OBJECT_ALLOCATION_FAILURE if there is a failure to allocate memory for sub-buffer object. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

If blocking_read is CL_TRUE i.e. the read command is blocking, clEnqueueReadBufferRect does not return until the buffer data has been read and copied into memory pointed to by ptr. If blocking_read is CL_FALSE i.e. the read command is non-blocking, clEnqueueReadBufferRect queues a non-blocking read command and returns. The contents of the buffer that ptr points to cannot be used until the read command has completed. The event argument argument returns an event object which can be used to query the execution status of the read command. When the read command has completed, the contents of the buffer that ptr points to can be used by the application. buffer_origin The (x, y, z) offset in the memory region associated with buffer. For a 2D rectangle region, the z value given by buffer_origin[2] should be 0. The offset in bytes is computed as buffer_origin[2] * buffer_slice_pitch + buffer_origin[1] * buffer_row_pitch + buffer_origin[0]. host_origin The (x, y, z) offset in the memory region pointed to by ptr. For a 2D rectangle region, the z value given by host_origin[2] should be 0. The offset in bytes is computed as host_origin[2] * host_slice_pitch + host_origin[1] * host_row_pitch + host_origin[0]. region The (width, height, depth) in bytes of the 2D or 3D rectangle being read or written. For a 2D rectangle copy, the depth value given by region[2] should be 1. buffer_row_pitch The length of each row in bytes to be used for the memory region associated with buffer. If buffer_row_pitch is 0, buffer_row_pitch is computed as region[0]. buffer_slice_pitch The length of each 2D slice in bytes to be used for the memory region associated with buffer. If buffer_slice_pitch is 0, buffer_slice_pitch is computed as region[1] * buffer_row_pitch. host_row_pitch The length of each row in bytes to be used for the memory region pointed to by ptr. If host_row_pitch is 0, host_row_pitch is computed as region[0]. host_slice_pitch The length of each 2D slice in bytes to be used for the memory region pointed to by ptr. If host_slice_pitch is 0, host_slice_pitch is computed as region[1] * host_row_pitch. ptr The pointer to buffer in host memory where data is to be read into. event_wait_list num_events_in_wait_list event_wait_list and num_events_in_wait_list specify events that need to complete before this particular command can be executed. If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. event Returns an event object that identifies this particular read command and can be used to query or queue a wait for this particular command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. If the event_wait_list and the event arguments are not NULL, the event argument should not refer to an element of the event_wait_list array. Notes Calling clEnqueueReadBufferRect to read a region of the buffer object with the ptr argument value set to host_ptr and host_origin, buffer_origin values are the same, where host_ptr is a pointer to the memory region specified when the buffer object being read is created with CL_MEM_USE_HOST_PTR, must meet the same requirements given for clEnqueueReadBuffer. Calling clEnqueueWriteBufferRect to update the latest bits in a region of the buffer object with the ptr argument value set to host_ptr and host_origin, buffer_origin values are the same, where host_ptr is a pointer to the memory region specified when the buffer object being written is created with CL_MEM_USE_HOST_PTR, must meet the following requirements in order to avoid undefined behavior: The host memory region given by (buffer_origin region) contains the latest bits when the enqueued write command begins execution. The buffer object or memory objects created from this buffer object are not mapped. The buffer object or memory objects created from this buffer object are not used by any command-queue until the write command has finished execution. Errors clEnqueueReadBufferRect returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors: CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_CONTEXT if the context associated with command_queue and buffer are not the same or if the context associated with command_queue and events in event_wait_list are not the same. CL_INVALID_MEM_OBJECT if buffer is not a valid buffer object. CL_INVALID_VALUE if the region being read specified by (buffer_origin, region, buffer_row_pitch, buffer_slice_pitch) is out of bounds. CL_INVALID_VALUE if ptr is a NULL value. CL_INVALID_VALUE if any region array element is 0. CL_INVALID_VALUE if buffer_row_pitch is not 0 and is less than region[0]. CL_INVALID_VALUE if host_row_pitch is not 0 and is less than region[0]. CL_INVALID_VALUE if buffer_slice_pitch is not 0 and is less than region[1] * buffer_row_pitch and not a multiple of buffer_row_pitch. CL_INVALID_VALUE if host_slice_pitch is not 0 and is less than region[1] * host_row_pitch and not a multiple of host_row_pitch. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list > 0, or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects in event_wait_list are not valid events. CL_MISALIGNED_SUB_BUFFER_OFFSET if buffer is a sub-buffer object and offset specified when the sub-buffer object is created is not aligned to CL_DEVICE_MEM_BASE_ADDR_ALIGN value for device associated with queue. CL_EXEC_STATUS_ERROR_FOR_EVENTS_IN_WAIT_LIST if the read and write operations are blocking and the execution status of any of the events in event_wait_list is a negative integer value. CL_MEM_OBJECT_ALLOCATION_FAILURE if there is a failure to allocate memory for data store associated with buffer. CL_INVALID_OPERATION if clEnqueueReadBufferRect is called on buffer which has been created with CL_MEM_HOST_WRITE_ONLY or CL_MEM_HOST_NO_ACCESS. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

Description These are the data types available in the OpenCL C programming language. Click on a category name in the table below to see information about specific data types. Data type category Included data types Scalar data types bool, char, cl_char, unsigned char, uchar, cl_uchar, short, cl_short, unsigned short, ushort, int, unsigned int, uint, long, unsigned long, ulong, float, half, size_t, ptrdiff_t, intptr_t, uintptr_t, void, double, and half floating point types. Vector data types charn, ucharn, shortn, ushortn, intn, uintn, longn, ulongn, floatn, doublen, and optional halfn types. Abstract data types cl_platform_id, cl_device_id, cl_context, cl_command_queue, cl_mem, cl_program, cl_kernel, cl_event, and cl_sampler. Reserved Data Types booln, halfn, quad, quadn, complex half, complex halfn, imaginary half, imaginary halfn, complex float, complex floatn, imaginary float, imaginary floatn, complex double, complex doublen, imaginary double, imaginary doublen, complex quad, complex quadn, imaginary quad, imaginary quadn, floatnxm, doublenxm, long double, long doublen, long long, long longn, unsigned long long, ulong long, and ulong longn. Other data types image2d_t, image3d_t, image2d_array_t, image1d_t, image31_buffer_t, image1d_array_t, sampler_t, and event_t. Alignment of Types A data item declared to be a data type in memory is always aligned to the size of the data type in bytes. For example, a float4 variable will be aligned to a 16-byte boundary, and a char2 variable will be aligned to a 2-byte boundary. For 3-component vector data types, the size of the data type is 4 * sizeof(component). This means that a 3-component vector data type will be aligned to a 4 * sizeof(component) boundary. The vload3 and vstore3 built-in functions can be used to read and write, respectively, 3-component vector data types from an array of packed scalar data type. A built-in data type that is not a power of two bytes in size must be aligned to the next larger power of two. This rule applies to built-in types only, not structs or unions. The OpenCL compiler is responsible for aligning data items to the appropriate alignment as required by the data type. For arguments to a __kernel function declared to be a pointer to a data type, the OpenCL compiler can assume that the pointee is always appropriately aligned as required by the data type. The behavior of an unaligned load or store is undefined, except for the vloadn, vload_halfn, vstoren, and vstore_halfn functions. The vector load functions can read a vector from an address aligned to the element type of the vector. The vector store functions can write a vector to an address aligned to the element type of the vector. The user is responsible for ensuring that data passed into and out of OpenCL buffers are natively aligned relative to the start of the buffer as described above. This implies that OpenCL buffers created with CL_MEM_USE_HOST_PTR need to provide an appropriately aligned host memory pointer that is aligned to the data types used to access these buffers in a kernel(s). As well, the user is responsible to ensure that data passed into and out of OpenCL images are properly aligned to the granularity of the data representing a single pixel (e.g. image_num_channels * sizeof(image_channel_data_type)) except for CL_RGB and CL_RGBx images where the data must be aligned to the granularity of a single channel in a pixel (i.e. sizeof(image_channel_data_type)). OpenCL makes no requirement about the alignment of OpenCL application defined data types outside of buffers and images, except that the underlying vector primitives (e.g. __cl_float4) where defined shall be directly accessible as such using appropriate named fields in the cl_type union. Nevertheless, it is recommended that the cl_platform.h header should attempt to naturally align OpenCL defined application data types (e.g. cl_float4) according to their type.

This is designed to function analogously to the OpenGL interoperability as defined in sections 9.7 and 9.8. If this extension is supported by an implementation, the string "cl_khr_d3d10_sharing" will be present in the CL_PLATFORM_EXTENSIONS or CL_DEVICE_EXTENSIONS string described in the table of allowed values for param_name for clGetDeviceInfo. As currently proposed the interfaces for this extension would be provided in cl_d3d10.h. If the cl_khr_d3d10_sharing extension is supported, then the following functions are enabled: clGetDeviceIDsFromD3D10KHR clCreateFromD3D10BufferKHR clCreateFromD3D10Texture2DKHR clCreateFromD3D10Texture3DKHR clEnqueueAcquireD3D10ObjectsKHR clEnqueueReleaseD3D10ObjectsKHR The OpenCL functions enabled by the cl_khr_d3d10_sharing extension allow applications to use Direct3D 10 resources as OpenCL memory objects. This allows efficient sharing of data between OpenCL and Direct3D 10. The OpenCL API may be used to execute kernels that read and/or write memory objects that are also Direct3D 10 resources. An OpenCL image object may be created from a Direct3D 10 texture resource. An OpenCL buffer object may be created from a Direct3D 10 buffer resource. OpenCL memory objects may be created from Direct3D 10 objects if and only if the OpenCL context has been created from a Direct3D 10 device.

The OpenCL context associated with command_queue and memobj must be the same. mapped_ptr The host address returned by a previous call to clEnqueueMapBuffer or clEnqueueMapImage for memobj. event_wait_list , num_events_in_wait_list Specify events that need to complete before clEnqueueUnmapMemObject can be executed. If event_wait_list is NULL, then clEnqueueUnmapMemObject does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. event Returns an event object that identifies this particular copy command and can be used to query or queue a wait for this particular command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. clEnqueueBarrierWithWaitList can be used instead. Notes Reads or writes from the host using the pointer returned by clEnqueueMapBuffer or clEnqueueMapImage are considered to be complete. clEnqueueMapBuffer and clEnqueueMapImage increment the mapped count of the memory object. The initial mapped count value of a memory object is zero. Multiple calls to clEnqueueMapBuffer or clEnqueueMapImage on the same memory object will increment this mapped count by appropriate number of calls. clEnqueueUnmapMemObject decrements the mapped count of the memory object. clEnqueueMapBuffer and clEnqueueMapImage act as synchronization points for a region of the buffer object being mapped. Errors clEnqueueUnmapMemObject returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors:. CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_MEM_OBJECT if memobj is not a valid memory object. CL_INVALID_VALUE if mapped_ptr is not a valid pointer returned by clEnqueueMapBuffer or clEnqueueMapImage for memobj. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list > 0, or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects in event_wait_list are not valid events. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host. CL_INVALID_CONTEXT if the context associated with command_queue and memobj are not the same or if the context associated with command_queue and events in event_wait_list are not the same.

If blocking_map is CL_TRUE, clEnqueueMapBuffer does not return until the specified region in buffer is mapped into the host address space and the application can access the contents of the mapped region using the pointer returned by clEnqueueMapBuffer. If blocking_map is CL_FALSE i.e. map operation is non-blocking, the pointer to the mapped region returned by clEnqueueMapBuffer cannot be used until the map command has completed. The event argument returns an event object which can be used to query the execution status of the map command. When the map command is completed, the application can access the contents of the mapped region using the pointer returned by clEnqueueMapBuffer. map_flags A bit-bield with the following supported values. cl_map_flags Description CL_MAP_READ This flag specifies that the region being mapped in the memory object is being mapped for reading. The pointer returned by clEnqueueMapBuffer or clEnqueueMapImage is guaranteed to contain the latest bits in the region being mapped when the clEnqueueMapBuffer or clEnqueueMapImage command has completed. CL_MAP_WRITE This flag specifies that the region being mapped in the memory object is being mapped for writing. The pointer returned by clEnqueueMapBuffer or clEnqueueMapImage is guaranteed to contain the latest bits in the region being mapped when the clEnqueueMapBuffer or clEnqueueMapImage command has completed. CL_MAP_WRITE_INVALIDATE_REGION This flag specifies that the region being mapped in the memory object is being mapped for writing. The contents of the region being mapped are to be discarded. This is typically the case when the region being mapped is overwritten by the host. This flag allows the implementation to no longer guarantee that the pointer returned by clEnqueueMapBuffer or clEnqueueMapImage contains the latest bits in the region being mapped which can be a significant performance enhancement. CL_MAP_READ or CL_MAP_WRITE and CL_MAP_WRITE_INVALIDATE_REGION are mutually exclusive. buffer A valid buffer object. The OpenCL context associated with command_queue and buffer must be the same. offset, size The offset in bytes and the size of the region in the buffer object that is being mapped. event_wait_list, num_events_in_wait_list Specify events that need to complete before this particular command can be executed. If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. event Returns an event object that identifies this particular copy command and can be used to query or queue a wait for this particular command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. If the event_wait_list and the event arguments are not NULL, the event argument should not refer to an element of the event_wait_list array. errcode_ret Returns an appropriate error code. If errcode_ret is NULL, no error code is returned. Notes The returned pointer maps a region starting at offset and is at least size bytes in size. The result of a memory access outside this region is undefined. If the buffer object is created with CL_MEM_USE_HOST_PTR set in mem_flags, the following will be true: The host_ptr specified in clCreateBuffer is guaranteed to contain the latest bits in the region being mapped when the clEnqueueMapBuffer command has completed. The pointer value returned by clEnqueueMapBuffer will be derived from the host_ptr specified when the buffer object is created. Mapped buffer objects are unmapped using clEnqueueUnmapMemObject. clEnqueueMapBuffer and clEnqueueMapImage increment the mapped count of the memory object. The initial mapped count value of a memory object is zero. Multiple calls to clEnqueueMapBuffer or clEnqueueMapImage on the same memory object will increment this mapped count by appropriate number of calls. clEnqueueUnmapMemObject decrements the mapped count of the memory object. clEnqueueMapBuffer and clEnqueueMapImage act as synchronization points for a region of the buffer object being mapped. Errors clEnqueueMapBuffer will return a pointer to the mapped region if the function is executed successfully. The errcode_ret is set to CL_SUCCESS. A NULL pointer is returned otherwise with one of the following error values returned in errcode_ret: CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_CONTEXT if the context associated with command_queue and image are not the same or if the context associated with command_queue and events in event_wait_list are not the same. CL_INVALID_MEM_OBJECT if image is not a valid image object. CL_INVALID_VALUE if region being mapped given by (offset, size) is out of bounds or if size is 0 or values specified in map_flags are not valid. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list > 0, or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects in event_wait_list are not valid events. CL_MISALIGNED_SUB_BUFFER_OFFSET if buffer is a sub-buffer object and offset specified when the sub-buffer object is created is not aligned to CL_DEVICE_MEM_BASE_ADDR_ALIGN value for device associated with queue. CL_MAP_FAILURE if there is a failure to map the requested region into the host address space. This error cannot occur for image objects created with CL_MEM_USE_HOST_PTR or CL_MEM_ALLOC_HOST_PTR. CL_EXEC_STATUS_ERROR_FOR_EVENTS_IN_WAIT_LIST if the map operation is blocking and the execution status of any of the events in event_wait_list is a negative integer value. CL_MEM_OBJECT_ALLOCATION_FAILURE if there is a failure to allocate memory for data store associated with buffer. CL_INVALID_OPERATION if buffer has been created with CL_MEM_HOST_WRITE_ONLY or CL_MEM_HOST_NO_ACCESS and CL_MAP_READ is set in map_flags or if buffer has been created with CL_MEM_HOST_READ_ONL or CL_MEM_HOST_NO_ACCESS and CL_MAP_WRITE or CL_MAP_WRITE_INVALIDATE_REGION is set in map_flags. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

This keyword is followed by an attribute specification inside double parentheses. Two attributes are currently defined for types: aligned, and packed. You may specify type attributes in an enum, struct, or union type declaration or definition, or for other types in a typedef declaration. For an enum, struct, or union type, you may specify attributes either between the enum, struct or union tag and the name of the type, or just past the closing curly brace of the definition. The former syntax is preferred. aligned (<varname>alignment</varname>) This attribute specifies a minimum alignment (in bytes) for variables of the specified type. For example, the declarations: struct S { short f[3]; } __attribute__ ((aligned (8))); typedef int more_aligned_int __attribute__ ((aligned (8))); force the compiler to ensure (as far as it can) that each variable whose type is struct S or more_aligned_int will be allocated and aligned at least on a 8-byte boundary. Note that the alignment of any given struct or union type is required by the ISO C standard to be at least a perfect multiple of the lowest common multiple of the alignments of all of the members of the struct or union in question and must also be a power of two. This means that you can effectively adjust the alignment of a struct or union type by attaching an aligned attribute to any one of the members of such a type, but the notation illustrated in the example above is a more obvious, intuitive, and readable way to request the compiler to adjust the alignment of an entire struct or union type. As in the preceding example, you can explicitly specify the alignment (in bytes) that you wish the compiler to use for a given struct or union type. Alternatively, you can leave out the alignment factor and just ask the compiler to align a type to the maximum useful alignment for the target machine you are compiling for. For example, you could write: struct S { short f[3]; } __attribute__ ((aligned)); Whenever you leave out the alignment factor in an aligned attribute specification, the compiler automatically sets the alignment for the type to the largest alignment which is ever used for any data type on the target machine you are compiling for. In the example above, the size of each short is 2 bytes, and therefore the size of the entire struct S type is 6 bytes. The smallest power of two which is greater than or equal to that is 8, so the compiler sets the alignment for the entire struct S type to 8 bytes. Note that the effectiveness of aligned attributes may be limited by inherent limitations of the OpenCL device and compiler. For some devices, the OpenCL compiler may only be able to arrange for variables to be aligned up to a certain maximum alignment. If the OpenCL compiler is only able to align variables up to a maximum of 8 byte alignment, then specifying aligned(16) in an __attribute__ will still only provide you with 8 byte alignment. See your platform-specific documentation for further information. The aligned attribute can only increase the alignment; but you can decrease it by specifying packed as well. See below. packed The packed attribute, attached to the struct or union type definition, specifies that each member of the structure or union is placed to minimize the memory required. When attached to an enum definition, it indicates that the smallest integral type should be used. Specifying this attribute for struct and union types is equivalent to specifying the packed attribute on each of the structure or union members. In the following example struct my_packed_struct's members are packed closely together, but the internal layout of its s member is not packed. To do that, struct my_unpacked_struct would need to be packed, too. struct my_unpacked_struct { char c; int i; }; struct __attribute__ ((packed)) my_packed_struct { char c; int i; struct my_unpacked_struct s; }; You may only specify this attribute on the definition of a enum, struct, or union, not on a typedef which does not also define the enumerated type, structure or union.

All of the functions listed in the following table are performed in one atomic transaction. These transactions are atomic for the device executing these atomic functions. There is no guarantee of atomicity if the atomic operations to the same memory location are being performed by kernels executing on multiple devices. Atomic operations on 64-bit integers and 32-bit integers (and float) are also atomic w.r.t. each other.

If device_list is a NULL value, the compile is performed for all devices associated with program. If device_list is a non-NULL value, the compile is performed for devices specified in this list. num_devices The number of devices listed in device_list. options A pointer to a null-terminated string of characters that describes the compilation options to be used for building the program executable. The list of supported options is as described below. num_input_headers Specifies the number of programs that describe headers in the array referenced by input_headers. input_headers An array of program embedded headers created with clCreateProgramWithSource. header_include_names An array that has a one to one correspondence with input_headers. Each entry in header_include_names specifies the include name used by source in program that comes from an embedded header. The corresponding entry in input_headers identifies the program object which contains the header source to be used. The embedded headers are first searched before the headers in the list of directories specified by the –I compile option (as described in section 5.6.4.1). If multiple entries in header_include_names refer to the same header name, the first one encountered will be used. pfn_notify A function pointer to a notification routine. The notification routine is a callback function that an application can register and which will be called when the program executable has been built (successfully or unsuccessfully). If pfn_notify is not NULL, clCompileProgram does not need to wait for the compiler to complete and can return immediately once the compilation can begin. The compilation can begin if the context, program whose sources are being compiled, list of devices, input headers, programs that describe input headers and compiler options specified are all valid and appropriate host and device resources needed to perform the compile are available. If pfn_notify is NULL, clCompileProgram does not return until the compiler has completed. This callback function may be called asynchronously by the OpenCL implementation. It is the application’s responsibility to ensure that the callback function is thread-safe. user_data Passed as an argument when pfn_notify is called. user_data can be NULL. Notes Compiles a program’s source for all the devices or a specific device(s) in the OpenCL context associated with program. The pre-processor runs before the program sources are compiled. The compiled binary is built for all devices associated with program or the list of devices specified. The compiled binary can be queried using clGetProgramInfo(program, CL_PROGRAM_BINARIES, ...) and can be specified to clCreateProgramWithBinary to create a new program object. &buildOptionsInc; Errors clCompileProgram returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors: CL_INVALID_PROGRAM if program is not a valid program object. CL_INVALID_VALUE if device_list is NULL and num_devices is greater than zero, or if device_list is not NULL and num_devices is zero. CL_INVALID_VALUE if num_input_headers is zero and header_include_names or input_headers are not NULL or if num_input_headers is not zero and header_include_names or input_headers are NULL. CL_INVALID_VALUE if pfn_notify is NULL but user_data is not NULL. CL_INVALID_DEVICE if OpenCL devices listed in device_list are not in the list of devices associated with program. CL_INVALID_COMPILER_OPTIONS if the compiler options specified by options are invalid. CL_INVALID_OPERATION if the compilation or build of a program executable for any of the devices listed in device_list by a previous call to clCompileProgram or clBuildProgram for program has not completed. CL_COMPILER_NOT_AVAILABLE if a compiler is not available i.e. CL_DEVICE_COMPILER_AVAILABLE specified in in the table of allowed values for param_name for clGetDeviceInfo is set to CL_FALSE. CL_COMPILE_PROGRAM_FAILURE if there is a failure to compile the program source. This error will be returned if clCompileProgram does not return until the compile has completed. CL_INVALID_OPERATION if there are kernel objects attached to program. CL_INVALID_OPERATION if program has no source i.e. it has not been created with clCreateProgramWithSource.

Notes clCreateCommandQueue performs an implicit retain. This is very helpful for 3rd party libraries, which typically get a command-queue passed to them by the application. However, it is possible that the application may delete the command-queue without informing the library. Allowing functions to attach to (i.e. retain) and release a command-queue solves the problem of a command-queue being used by a library no longer being valid.

An image memory object can be accessed by specific function calls that read from and/or write to specific locations in the image. Image memory objects that are being read by a kernel should be declared with the __read_only qualifier. write_image calls to image memory objects declared with the __read_only qualifier will generate a compilation error. Image memory objects that are being written to by a kernel should be declared with the __write_only qualifier. read_image calls to image memory objects declared with the __write_only qualifier will generate a compilation error. read_image and write_image calls to the same image memory object in a kernel are not supported. The read_image calls returns a four component floating-point, integer or unsigned integer color value. The color values returned by read_image are identified as x, y, z, w where x refers to the red component, y refers to the green component, z refers to the blue component and w refers to the alpha component. khronos-opencl-man-1.0~svn22836/popcount.xml0000644000175000017500000001025311660441607020667 0ustar mathieumathieu ]> popcount popcount 2007-2011 The Khronos Group Inc.

The following rules apply to functions that are declared with this qualifier: It can be executed on the device only It can be called by the host It is just a regular function call if a __kernel function is called by another kernel function. Kernel functions with variables declared inside the function with the __local or local qualifier can be called by the host using appropriate APIs such as clEnqueueNDRangeKernel, and clEnqueueTask. The behavior of calling kernel functions with variables declared inside the function with the __local or local qualifier from other kernel functions is implementation-defined. The __kernel and kernel names are reserved for use as functions qualifiers and shall not be used otherwise. Optional Attribute Qualifiers The __kernel qualifier can be used with the keyword __attribute__ to declare additional information about the kernel function as described below. The optional __attribute__((vec_type_hint(<type>))) is a hint to the compiler and is intended to be a representation of the computational width of the __kernel, and should serve as the basis for calculating processor bandwidth utilization when the compiler is looking to autovectorize the code. In the __attribute__((vec_type_hint(<type>))) qualifier <type> is one of the built-in vector types or the constituent scalar element types. If vec_type_hint (<type>) is not specified, the kernel is assumed to have the __attribute__((vec_type_hint(int))) qualifier. Implicit in autovectorization is the assumption that any libraries called from the __kernel must be recompilable at run time to handle cases where the compiler decides to merge or separate workitems. This probably means that such libraries can never be hard coded binaries or that hard coded binaries must be accompanied either by source or some retargetable intermediate representation. This may be a code security question for some. For example, where the developer specified a width of float4, the compiler should assume that the computation usually uses up 4 lanes of a float vector, and would decide to merge work-items or possibly even separate one work-item into many threads to better match the hardware capabilities. A conforming implementation is not required to autovectorize code, but shall support the hint. A compiler may autovectorize, even if no hint is provided. If an implementation merges N work-items into one thread, it is responsible for correctly handling cases where the number of global or local work-items in any dimension modulo N is not zero. If for example, a __kernel function is declared with __attribute__(( vec_type_hint (float4))) (meaning that most operations in the __kernel are explicitly vectorized using float4) and the kernel is running using Intel® Advanced Vector Instructions (Intel® AVX) which implements a 8-float-wide vector unit, the autovectorizer might choose to merge two work-items to one thread, running a second work-item in the high half of the 256-bit AVX register. As another example, a Power4 machine has two scalar double precision floating-point units with an 6-cycle deep pipe. An autovectorizer for the Power4 machine might choose to interleave six kernels declared with the __attribute__(( vec_type_hint (double2))) qualifier into one hardware thread, to ensure that there is always 12-way parallelism available to saturate the FPUs. It might also choose to merge 4 or 8 work-items (or some other number) if it concludes that these are better choices, due to resource utilization concerns or some preference for divisibility by 2. The optional __attribute__((work_group_size_hint(X, Y, Z))) is a hint to the compiler and is intended to specify the work-group size that may be used i.e. value most likely to be specified by the local_work_size argument to clEnqueueNDRangeKernel. For example the __attribute__((work_group_size_hint(1, 1, 1))) is a hint to the compiler that the kernel will most likely be executed with a work-group size of 1. The optional __attribute__((reqd_work_group_size(X, Y, Z))) is the work-group size that must be used as the local_work_size argument to clEnqueueNDRangeKernel. This allows the compiler to optimize the generated code appropriately for this kernel. The optional __attribute__((reqd_work_group_size(X, Y, Z))), if specified, must be (1, 1, 1) if the kernel is executed via clEnqueueTask. If Z is one, the work_dim argument to clEnqueueNDRangeKernel can be 2 or 3. If Y and Z are one, the work_dim argument to clEnqueueNDRangeKernel can be 1, 2 or 3. Notes Kernel functions with variables declared inside the function with the __local or local qualifier can be called by the host using appropriate APIs such as clEnqueueNDRangeKernel, and clEnqueueTask. The behavior of calling kernel functions with variables declared inside the function with the __local and local qualifier from other kernel functions is implementation-defined. The __kernel and kernel names are reserved for use as functions qualifiers and shall not be used otherwise. Example // autovectorize assuming float4 as the // basic computation width __kernel __attribute__((vec_type_hint(float4))) void foo( __global float4 *p ) { .... // autovectorize assuming double as the // basic computation width __kernel __attribute__((vec_type_hint(double))) void foo( __global float4 *p ){ .... // autovectorize assuming int (default) // as the basic computation width __kernel void foo( __global float4 *p ){ ....

The C syntax for type qualifiers is extended in OpenCL to include an address space name as a valid type qualifier. If the type of an object is qualified by an address space name, the object is allocated in the specified address name; otherwise, the object is allocated in the generic address space. The address space names without the __prefix i.e. global, local, constant and private may be substituted for the corresponding address space names with the __prefix. The generic address space name for arguments to a function in a program, or local variables of a function is __private. All function arguments shall be in the __private address space. __kernel function arguments declared to be a pointer of a type can point to one of the following address spaces only: __global, __local or __constant. A pointer to address space A can only be assigned to a pointer to the same address space A. Casting a pointer to address space A to a pointer to address space B is illegal. Function arguments of type image2d_t, image3d_t, image2d_array_t, image1d_t, image1d_buffer_t, and image1d_array_t refer to image memory objects allocated in the __global address space. khronos-opencl-man-1.0~svn22836/clEnqueueReleaseDX9MediaSurfacesKHR.xml0000644000175000017500000003074411660441607025604 0ustar mathieumathieu ]> clEnqueueReleaseDX9MediaSurfacesKHR clEnqueueReleaseDX9MediaSurfacesKHR 2007-2011 The Khronos Group Inc.

Notes Used to release OpenCL memory objects that have been created from media surfaces. The media surfaces are released by the OpenCL context associated with command_queue. OpenCL memory objects created from media surfaces which have been acquired by OpenCL must be released by OpenCL before they may be accessed by the media adapter API. Accessing a media surface while its corresponding OpenCL memory object is acquired is in error and will result in undefined behavior, including but not limited to possible OpenCL errors, data corruption, and program termination.

The maximum error is implementation-defined. Notes &mathFunctionsInc; Functions with the half_ prefix are implemented with a minimum of 10-bits of accuracy i.e. an ULP value less than or equal to 8192 ulp. Functions with the native__ prefix may map to one or more native device instructions and will typically have better performance compared to the corresponding functions (without the native__ prefix). The accuracy (and in some cases the input range(s)) of these functions is implementation-defined.

Reads and writes to the same 3D image memory object are not allowed in a kernel. An application that wants to use this extension to write to 3D image memory objects will need to include the #pragma OPENCL EXTENSION cl_khr_3d_image_writes : enable directive in the OpenCL program source. These functions write color value to location specified by coordinate (x, y, z) in the 3D image object specified by image. Appropriate data format conversion to the specified image format is done before writing the color value. coord.x, coord.y and coord.z are considered to be unnormalized coordinates and must be in the range 0 ... image width - 1, 0 ... image height - 1 and 0 ... image depth - 1. write_imagef can only be used with image objects created with image_channel_data_type set to one of the pre-defined packed formats or set to CL_SNORM_INT8, CL_UNORM_INT8, CL_SNORM_INT16, CL_UNORM_INT16, CL_HALF_FLOAT or CL_FLOAT. Appropriate data format conversion will be done to convert channel data from a floating-point value to actual data format in which the channels are stored. write_imagei can only be used with image objects created with image_channel_data_type set to one of the following values: CL_SIGNED_INT8, CL_SIGNED_INT16, or CL_SIGNED_INT32. write_imageui can only be used with image objects created with image_channel_data_type set to one of the following values: CL_UNSIGNED_INT8, CL_UNSIGNED_INT16, or CL_UNSIGNED_INT32. The behavior of write_imagef, write_imagei and write_imageui for image objects with image_channel_data_type values not specified in the description above or with (x, y, z) coordinate values that are not in the range (0 ... image width - 1, 0 ... image height - 1, 0 ... image depth - 1), respectively, is undefined. write_imageh can only be used with image objects created with image_channel_data_type set to one of the pre-defined packed formats or set to CL_SNORM_INT8, CL_UNORM_INT8, CL_SNORM_INT16, CL_UNORM_INT16 or CL_HALF_FLOAT.

A kernel cannot read from and write to the same image object. The __read_only (or read_only) and __write_only (or write_only) qualifiers must be used with image object arguments to declare if the image object is being read or written by a kernel. The default qualifier is __read_only. Notes The __read_only, __write_only, __read_write, read_only, write_only and read_write names are reserved for use as access qualifiers and shall not be used otherwise. Example In the example below, imageA is a read-only 2D image object, and imageB is a write-only 2D image object. __kernel void foo (read_only image2d_t imageA, write_only image2d_t imageB) { ... } Specification OpenCL Specification khronos-opencl-man-1.0~svn22836/clEnqueueFillBuffer.xml0000644000175000017500000003573411660441607022722 0ustar mathieumathieu clEnqueueFillBuffer clEnqueueFillBuffer 2007-2011 The Khronos Group Inc.

The OpenCL context associated with command_queue and buffer must be the same. buffer A valid buffer object. pattern A pointer to the data pattern of size pattern_size in bytes. pattern will be used to fill a region in buffer starting at offset and is size bytes in size. The data pattern must be a scalar or vector integer or floating-point data type. For example, if buffer is to be filled with a pattern of float4 values, then pattern will be a pointer to a cl_float4 value and pattern_size will be sizeof(cl_float4). The maximum value of pattern_size is the size of the largest integer or floating-point vector data type supported by the OpenCL device. The memory associated with pattern can be reused or freed after the function returns. offset The location in bytes of the region being filled in buffer and must be a multiple of pattern_size. size The size in bytes of region being filled in buffer and must be a multiple of pattern_size. event_wait_list , num_events_in_wait_list Specify events that need to complete before this particular command can be executed. If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. event Returns an event object that identifies this particular write command and can be used to query or queue a wait for this particular command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. clEnqueueBarrierWithWaitList can be used instead. If the event_wait_list and the event arguments are not NULL, the event argument should not refer to an element of the event_wait_list array. Notes Enqueues a command to fill a buffer object with a pattern of a given pattern size. The usage information which indicates whether the memory object can be read or written by a kernel and/or the host and is given by the cl_mem_flags argument value specified when buffer is created is ignored by clEnqueueFillBuffer. Errors clEnqueueFillBuffer returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors. CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_CONTEXT if the context associated with command_queue and buffer are not the same or if the context associated with command_queue and events in event_wait_list are not the same. CL_INVALID_MEM_OBJECT if buffer is not a valid buffer object. CL_INVALID_VALUE if offset or offset + size require accessing elements outside the buffer buffer object respectively. CL_INVALID_VALUE if pattern is NULL or if pattern_size is 0 or if pattern_size is not one of {1, 2, 4, 8, 16, 32, 64, 128}. CL_INVALID_VALUE if offset and size are not a multiple of pattern_size. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list > 0, or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects in event_wait_list are not valid events. CL_MISALIGNED_SUB_BUFFER_OFFSET if buffer is a sub-buffer object and offset specified when the sub-buffer object is created is not aligned to CL_DEVICE_MEM_BASE_ADDR_ALIGN value for device associated with queue. CL_MEM_OBJECT_ALLOCATION_FAILURE if there is a failure to allocate memory for data store associated with buffer. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

CL_DEVICE_PRINTF_BUFFER_SIZE size_t Maximum size of the internal buffer that holds the output of printf calls from a kernel. The minimum value for the FULL profile is 1 MB. CL_DEVICE_PREFERRED_INTEROP_USER_SYNC cl_bool Is CL_TRUE if the device's preference is for the user to be responsible for synchronization, when sharing memory objects between OpenCL and other APIs such as DirectX, CL_FALSE if the device / implementation has a performant path for performing synchronization of memory object shared between OpenCL and other APIs such as DirectX CL_DEVICE_PROFILE char[] OpenCL profile string. Returns the profile name supported by the device (see note). The profile name returned can be one of the following strings: FULL_PROFILE - if the device supports the OpenCL specification (functionality defined as part of the core specification and does not require any extensions to be supported). EMBEDDED_PROFILE - if the device supports the OpenCL embedded profile. CL_DEVICE_PROFILING_TIMER_RESOLUTION size_t Describes the resolution of device timer. This is measured in nanoseconds. CL_DEVICE_QUEUE_PROPERTIES cl_command_- queue_properties Describes the command-queue properties supported by the device. This is a bit-field that describes one or more of the following values: CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE CL_QUEUE_PROFILING_ENABLE These properties are described in the table for clCreateCommandQueue. The mandated minimum capability is CL_QUEUE_PROFILING_ENABLE. CL_DEVICE_REFERENCE_COUNT cl_uint Returns the device reference count. If the device is a root-level device, a reference count of one is returned. CL_DEVICE_SINGLE_FP_CONFIG cl_device_-fp_config Describes single precision floating-point capability of the device. This is a bit-field that describes one or more of the following values: CL_FP_DENORM - denorms are supported CL_FP_INF_NAN - INF and quiet NaNs are supported CL_FP_ROUND_TO_NEAREST - round to nearest even rounding mode supported CL_FP_ROUND_TO_ZERO - round to zero rounding mode supported CL_FP_ROUND_TO_INF - round to +ve and -ve infinity rounding modes supported CL_FP_FMA - IEEE754-2008 fused multiply-add is supported CL_FP_CORRECTLY_ROUNDED_DIVIDE_SQRT - divide and sqrt are correctly rounded as defined by the IEEE754 specification. CL_FP_SOFT_FLOAT - Basic floating-point operations (such as addition, subtraction, multiplication) are implemented in software. The mandated minimum floating-point capability for devices that are not of type CL_DEVICE_TYPE_CUSTOM is CL_FP_ROUND_TO_NEAREST | CL_FP_INF_NAN. CL_DEVICE_TYPE cl_device_type The OpenCL device type. Currently supported values are one of or a combination of: CL_DEVICE_TYPE_CPU, CL_DEVICE_TYPE_GPU, CL_DEVICE_TYPE_ACCELERATOR, CL_DEVICE_TYPE_DEFAULT, a combination of the above types, or CL_DEVICE_TYPE_CUSTOM. CL_DEVICE_VENDOR char[] Vendor name string. CL_DEVICE_VENDOR_ID cl_uint A unique device vendor identifier. An example of a unique device identifier could be the PCIe ID. CL_DEVICE_VERSION char[] OpenCL version string. Returns the OpenCL version supported by the device. This version string has the following format: OpenCL<space><major_version.minor_version><space><vendor-specific information> The major_version.minor_version value returned will be 1.1. CL_DRIVER_VERSION char[] OpenCL software driver version string in the form major_number.minor_number. Notes CL_DEVICE_PROFILE: The platform profile returns the profile that is implemented by the OpenCL framework. If the platform profile returned is FULL_PROFILE, the OpenCL framework will support devices that are FULL_PROFILE and may also support devices that are EMBEDDED_PROFILE. The compiler must be available for all devices i.e. CL_DEVICE_COMPILER_AVAILABLE is CL_TRUE. If the platform profile returned is EMBEDDED_PROFILE, then devices that are only EMBEDDED_PROFILE are supported. The device queries described the table above should return the same information for a root-level device i.e. a device returned by clGetDeviceIDs and any sub-devices created from this device except for the following queries: CL_DEVICE_GLOBAL_MEM_CACHE_SIZE CL_DEVICE_BUILT_IN_KERNELS CL_DEVICE_PARENT_DEVICE CL_DEVICE_PARTITION_TYPE CL_DEVICE_REFERENCE_COUNT Errors clGetDeviceInfo returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns the following: CL_INVALID_DEVICE if device is not valid. CL_INVALID_VALUE if param_name is not one of the supported values or if size in bytes specified by param_value_size is less than size of return type as shown in the table above and param_value is not a NULL value or if param_name is a value that is available as an extension and the corresponding extension is not supported by the device. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

All devices used to create the OpenCL context associated with command_queue must support acquiring shared CL/GL objects. This constraint is enforced at context creation time. num_objects The number of memory objects to be acquired in mem_objects. mem_objects A pointer to a list of CL memory objects that correspond to GL objects. event_wait_list and num_events_in_wait_list Specify events that need to complete before this particular command can be executed. If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. event Returns an event object that identifies this command and can be used to query or queue a wait for the command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. If the event_wait_list and the event arguments are not NULL, the event argument should not refer to an element of the event_wait_list array If the cl_khr_gl_sharing extension is supported, if an OpenGL context is bound to the current thread, then any OpenGL commands which affect or access the contents of a memory object listed in the mem_objects list, and were issued on that OpenGL context prior to the call to clEnqueueAcquireGLObjects will complete before execution of any OpenCL commands following the clEnqueueAcquireGLObjects which affect or access any of those memory objects. If a non-NULL event object is returned, it will report completion only after completion of such OpenGL commands. Description These objects need to be acquired before they can be used by any OpenCL commands queued to a command-queue. The OpenGL objects are acquired by the OpenCL context associated with command_queue and can therefore be used by all command-queues associated with the OpenCL context. Notes &gl_syncInc; Errors Returns CL_SUCCESS if the function is executed successfully. If num_objects is 0 and mem_objects is NULL the function does nothing and returns CL_SUCCESS. Otherwise, it returns one of the following errors: CL_INVALID_VALUE if num_objects is zero and mem_objects is not a NULL value or if num_objects > 0 and mem_objects is NULL. CL_INVALID_MEM_OBJECT if memory objects in mem_objects are not valid OpenCL memory objects. CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue.

A native user function can only be executed on a command-queue created on a device that has CL_EXEC_NATIVE_KERNEL capability set in CL_DEVICE_EXECUTION_CAPABILITIES as specified in the table of OpenCL Device Queries for clGetDeviceInfo. user_func A pointer to a host-callable user function. args A pointer to the args list that user_func should be called with. cb_args The size in bytes of the args list that args points to. The data pointed to by args and cb_args bytes in size will be copied and a pointer to this copied region will be passed to user_func. The copy needs to be done because the memory objects (cl_mem values) that args may contain need to be modified and replaced by appropriate pointers to global memory. When clEnqueueNativeKernel returns, the memory region pointed to by args can be reused by the application. num_mem_objects The number of buffer objects that are passed in args. mem_list A list of valid buffer objects, if num_mem_objects > 0. The buffer object values specified in mem_list are memory object handles (cl_mem values) returned by clCreateBuffer or NULL. args_mem_loc A pointer to appropriate locations that args points to where memory object handles (cl_mem values) are stored. Before the user function is executed, the memory object handles are replaced by pointers to global memory. event_wait_list and num_events_in_wait_list Specify events that need to complete before this particular command can be executed. If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. Notes The total number of read-only images specified as arguments to a kernel cannot exceed CL_DEVICE_MAX_READ_IMAGE_ARGS. Each 2D image array argument to a kernel declared with the read_only qualifier counts as one image. The total number of write-only images specified as arguments to a kernel cannot exceed CL_DEVICE_MAX_WRITE_IMAGE_ARGS. Each 2D image array argument to a kernel declared with the write-only qualifier counts as one image. Errors Returns CL_SUCCESS if the user function execution instance was successfully queued, or one of the errors below: CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_CONTEXT if context associated with command_queue and events in event-wait_list are not the same. CL_INVALID_VALUE if user_func is NULL. CL_INVALID_VALUE if args is a NULL value and cb_args > 0, or if args is a NULL value and num_mem_objects > 0. CL_INVALID_VALUE if args is not NULL and cb_args is 0. CL_INVALID_VALUE if num_mem_objects > 0 and mem_list or args_mem_loc are NULL. CL_INVALID_VALUE if num_mem_objects = 0 and mem_list or args_mem_loc are not NULL. CL_INVALID_OPERATION if the device associated with command_queue cannot execute the native kernel. CL_INVALID_MEM_OBJECT if one or more memory objects specified in mem_list are not valid or are not buffer objects. CL_OUT_OF_RESOURCES if there is a failure to queue the execution instance of kernel on the command-queue because of insufficient resources needed to execute the kernel. CL_MEM_OBJECT_ALLOCATION_FAILURE if there is a failure to allocate memory for data store associated with buffer objects specified as arguments to kernel. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list > 0, or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects in event_wait_list are not valid events.

Notes Decrements the event reference count. The event object is deleted once the reference count becomes zero, the specific command identified by this event has completed (or terminated) and there are no commands in the command-queues of a context that require a wait for this event to complete. Developers should be careful when releasing their last reference count on events created by clCreateUserEvent that have not yet been set to status of CL_COMPLETE or an error. If the user event was used in the event_wait_list argument passed to a clEnqueue*** API or another application host thread is waiting for it in clWaitForEvents, those commands and host threads will continue to wait for the event status to reach CL_COMPLETE or error, even after the user has released the object. Since in this scenario the developer has released his last reference count to the user event, it would be in principle no longer valid for him to change the status of the event to unblock all the other machinery. As a result the waiting tasks will wait forever, and associated events, cl_mem objects, command queues and contexts are likely to leak. In-order command queues caught up in this deadlock may cease to do any work. Errors Returns CL_SUCCESS if the function executed successfully. Otherwise, it returns one of the following errors: CL_INVALID_EVENT if event is not a valid event object.

This function is implemented with a minimum of 10-bits of accuracy i.e. an ULP value less than or equal to 8192 ulp. native_cos computes cosine over an implementation-defined range. The maximum error is implementation-defined. The vector versions of the math functions operate component-wise. The description is percomponent. The built-in math functions are not affected by the prevailing rounding mode in the calling environment, and always return the same value as they would if called with the round to nearest even rounding mode. For any specific use of a function, the actual type has to be the same for all arguments and the return type, unless otherwise specified. The functions with the native_ prefix may map to one or more native device instructions and will typically have better performance compared to the corresponding functions (without the native__ prefix). The accuracy (and in some cases the input range(s)) of these functions is implementation-defined. gentype indicates that the functions can take float, float2, float3, float4, float8 or float16 as the type for the arguments.

However, it is possible that the application may delete the context without informing the library. Allowing functions to attach to (i.e. retain) and release a context solves the problem of a context being used by a library no longer being valid. Errors Returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following values: CL_INVALID_CONTEXT if context is not a valid OpenCL context. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

For all scalar types, vec_step returns 1. The vec_step built-in functions that take a 3-component vector return 4. vec_step may also take a pure type as an argument, e.g. vec_step(float2) We use the generic type name gentypen (or gentypem) to indicate the built-in data types char{2|4|8|16}, uchar{2|4|8|16}, short{2|4|8|16}, ushort{2|4|8|16}, int{2|4|8|16}, uint{2|4|8|16}, long{2|4|8|16}, ulong{2|4|8|16}, or float{2|4|8|16} as the type for the arguments unless otherwise stated. We use the generic name ugentypen to indicate the built-in unsigned integer data types. If the double is supported, then gentypen (or gentypem) also indicate the built-in data types double{2|4|8|16}. The generic type name gentypen (or gentypem) may indicate the data type half{2|4|8|16} if the cl_khr_fp16 extension is supported.

For forms that take an image2d_array_t, use coord.xy to do an element lookup in the 2D image identified by coord.z in the 2D image array specified by image The samplerless read image functions behave exactly as the corresponding read image functions that take integer coordinates and a sampler with filter mode set to CLK_FILTER_NEAREST, normalized coordinates set to CLK_NORMALIZED_COORDS_FALSE and addressing mode to CLK_ADDRESS_NONE. read_imagef returns floating-point values in the range [0.0... 1.0] for image objects created with image_channel_data_type set to one of the predefined packed formats or CL_UNORM_INT8 or CL_UNORM_INT16. read_imagef returns floating-point values in the range [-1.0... 1.0] for image objects created with image_channel_data_type set to CL_SNORM_INT8, or CL_SNORM_INT16. read_imagef returns floating-point values for image objects created with image_channel_data_type set to CL_HALF_FLOAT or CL_FLOAT. The read_imagef calls that take integer coordinates must use a sampler with filter mode set to CLK_FILTER_NEAREST, normalized coordinates set to CLK_NORMALIZED_COORDS_FALSE and addressing mode set to CLK_ADDRESS_CLAMP_TO_EDGE, CLK_ADDRESS_CLAMP or CLK_ADDRESS_NONE; otherwise the values returned are undefined.

The vector versions of the integer functions operate component-wise. The description is per component. We use the generic type name gentype to indicate that the function can take char, char{2|3|4|8|16}, uchar, uchar{2|3|4|8|16}, short, short{2|3|4|8|16}, ushort, ushort{2|3|4|8|16}, int, int{2|3|4|8|16}, uint, uint{2|3|4|8|16}, long, long{2|3|4|8|16}, ulong, or ulong{2|3|4|8|16} as the type for the arguments. We use the generic type name ugentype to refer to unsigned versions of gentype. For example, if gentype is char4, ugentype is uchar4. We also use the generic type name sgentype to indicate that the function can take a scalar data type i.e. char, uchar, short, ushort, int, uint, long, or ulong as the type for the arguments. For built-in integer functions that take gentype and sgentype arguments, the gentype argument must be a vector or scalar version of the sgentype argument. For example, if sgentype is uchar, gentype must be uchar or uchar{2|3|4|8|16}. For vector versions, sgentype is implicitly widened to gentype as described in section 6.3.a of the OpenCL specification.

The OpenCL context associated with kernel and command_queue must be the same. num_events_in_wait_list , event_wait_list Sspecify events that need to complete before this particular command can be executed. If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. event Returns an event object that identifies this particular kernel execution instance. Event objects are unique and can be used to identify a particular kernel execution instance later on. If event is NULL, no event will be created for this kernel execution instance and therefore it will not be possible for the application to query or queue a wait for this particular kernel execution instance. Notes The kernel is executed using a single work-item. clEnqueueTask is equivalent to calling clEnqueueNDRangeKernel with work_dim = 1, global_work_offset = NULL, global_work_size[0] set to 1, and local_work_size[0] set to 1.

If an OpenCL memory object created from a Direct3D 11 resource is used while it is not currently acquired by OpenCL, the call attempting to use that OpenCL memory object will return CL_D3D11_RESOURCE_NOT_ACQUIRED_KHR. If CL_CONTEXT_INTEROP_USER_SYNC is not specified as CL_TRUE during context creation, clEnqueueAcquireD3D11ObjectsKHR provides the synchronization guarantee that any Direct3D 11 calls involving the interop device(s) used in the OpenCL context made before clEnqueueAcquireD3D11ObjectsKHR is called will complete executing before event reports completion and before the execution of any subsequent OpenCL work issued in command_queue begins. If the context was created with properties specifying CL_CONTEXT_INTEROP_USER_SYNC as CL_TRUE, the user is responsible for guaranteeing that any Direct3D 11 calls involving the interop device(s) used in the OpenCL context made before clEnqueueAcquireD3D11ObjectsKHR is called have completed before calling clEnqueueAcquireD3D11ObjectsKHR. &sharingD3D11Inc; &accessMappedInc; Errors Returns CL_SUCCESS returns CL_SUCCESS if the function is executed successfully.

Otherwise it returns one of the following errors: CL_INVALID_VALUE if num_objects is zero and mem_objects is not a NULL value or if num_objects > 0 and mem_objects is NULL. CL_INVALID_MEM_OBJECT if memory objects in mem_objects are not valid OpenCL memory objects or if memory objects in mem_objects have not been created from Direct3D 11 resources. CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_CONTEXT if context associated with command_queue was not created from a Direct3D 11 context.

The samplerless read image functions behave exactly as the corresponding read image functions that take integer coordinates and a sampler with filter mode set to CLK_FILTER_NEAREST, normalized coordinates set to CLK_NORMALIZED_COORDS_FALSE and addressing mode to CLK_ADDRESS_NONE. read_imageh returns half floating-point values in the range [0.0... 1.0] for image objects created with image_channel_data_type set to one of the predefined packed formats or CL_UNORM_INT8 or CL_UNORM_INT16. read_imageh returns half floating-point values in the range [-1.0... 1.0] for image objects created with image_channel_data_type set to CL_SNORM_INT8, or CL_SNORM_INT16. read_imageh returns half floating-point values for image objects created with image_channel_data_type set to CL_HALF_FLOAT. The read_imageh calls that take integer coordinates must use a sampler with filter mode set to CLK_FILTER_NEAREST, normalized coordinates set to CLK_NORMALIZED_COORDS_FALSE and addressing mode set to CLK_ADDRESS_CLAMP_TO_EDGE, CLK_ADDRESS_CLAMP or CLK_ADDRESS_NONE; otherwise the values returned are undefined.

A negative integer value causes all enqueued commands that wait on this user event to be terminated. clSetUserEventStatus can only be called once to change the execution status of event. Notes Enqueued commands that specify user events in the event_wait_list argument of clEnqueue*** commands must ensure that the status of these user events being waited on are set using clSetUserEventStatus before any OpenCL APIs that release OpenCL objects except for event objects are called; otherwise the behavior is undefined. Errors Returns CL_SUCCESS if the function was executed successfully. Otherwise, it returns one of the following errors CL_INVALID_EVENT if event is not a valid user event. CL_INVALID_VALUE if the execution_status is not CL_COMPLETE or a negative integer value. CL_INVALID_OPERATION if the execution_status for event has already been changed by a previous call to clSetUserEventStatus. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

Refer to the table for clCreateBuffer for a description of flags. Only CL_MEM_READ_ONLY, CL_MEM_WRITE_ONLY and CL_MEM_READ_WRITE values specified in the table at clCreateBuffer can be used. bufobj The name of a GL buffer object. The data store of the GL buffer object must have have been previously created by calling OpenGL function glBufferData, although its contents need not be initialized. The size of the data store will be used to determine the size of the CL buffer object. errcode_ret Returns an appropriate error code as described below. If errcode_ret is NULL, no error code is returned. Description The size of the GL buffer object data store at the time clCreateFromGLBuffer is called will be used as the size of buffer object returned by clCreateFromGLBuffer. If the state of a GL buffer object is modified through the GL API (e.g. glBufferData) while there exists a corresponding CL buffer object, subsequent use of the CL buffer object will result in undefined behavior.

CL_PROFILING_COMMAND_SUBMIT cl_ulong A 64-bit value that describes the current device time counter in nanoseconds when the command identified by event that has been enqueued is submitted by the host to the device associated with the command-queue. CL_PROFILING_COMMAND_START cl_ulong A 64-bit value that describes the current device time counter in nanoseconds when the command identified by event starts execution on the device. CL_PROFILING_COMMAND_END cl_ulong A 64-bit value that describes the current device time counter in nanoseconds when the command identified by event has finished execution on the device. Notes The unsigned 64-bit values returned can be used to measure the time in nano-seconds consumed by OpenCL commands. OpenCL devices are required to correctly track time across changes in device frequency and power states. The CL_DEVICE_PROFILING_TIMER_RESOLUTION specifies the resolution of the timer i.e. the number of nanoseconds elapsed before the timer is incremented. Event objects can be used to capture profiling information that measure execution time of a command. Profiling of OpenCL commands can be enabled either by using a command-queue created with CL_QUEUE_PROFILING_ENABLE flag set in properties argument to clCreateCommandQueue. Errors Returns CL_SUCCESS if the function is executed successfully and the profiling information has been recorded. Otherwise, it returns one of the following errors: CL_PROFILING_INFO_NOT_AVAILABLE if the CL_QUEUE_PROFILING_ENABLE flag is not set for the command-queue, if the execution status of the command identified by event is not CL_COMPLETE or if event is a user event object. CL_INVALID_VALUE if param_name is not valid, or if size in bytes specified by param_value_size is < size of return type as described in the above table and param_value is not NULL.

CL_GL_CONTEXT_KHR 0, OpenGL context handle OpenGL context to associated the OpenCL context with (available if the cl_khr_gl_sharing extension is enabled) CL_EGL_DISPLAY_KHR EGL_NO_DISPLAY, EGLDisplay handle EGLDisplay an OpenGL context was created with respect to (available if the cl_khr_gl_sharing extension is enabled) CL_GLX_DISPLAY_KHR None, X handle X Display an OpenGL context was created with respect to (available if the cl_khr_gl_sharing extension is enabled) CL_CGL_SHAREGROUP_KHR 0, CGL share group handle CGL share group to associate the OpenCL context with (available if the cl_khr_gl_sharing extension is enabled) CL_WGL_HDC_KHR 0, HDC handle HDC an OpenGL context was created with respect to (available if the cl_khr_gl_sharing extension is enabled) CL_CONTEXT_ADAPTER_D3D9_KHR IDirect3DDevice9 * Specifies an IDirect3DDevice9 to use for D3D9 interop (if the cl_khr_dx9_media_sharing extension is supported). CL_CONTEXT_ADAPTER_D3D9EX_KHR IDirect3DDeviceEx* Specifies an IDirect3DDevice9Ex to use for D3D9 interop (if the cl_khr_dx9_media_sharing extension is supported). CL_CONTEXT_ADAPTER_DXVA_KHR IDXVAHD_Device * Specifies an IDXVAHD_Device to use for DXVA interop (if the cl_khr_dx9_media_sharing extension is supported). CL_CONTEXT_D3D11_DEVICE_KHR ID3D11Device * Specifies the ID3D11Device * to use for Direct3D 11 interoperability. The default value is NULL. num_devices The number of devices specified in the devices argument. devices A pointer to a list of unique devices returned by clGetDeviceIDs or sub-devices created by clCreateSubDevices for a platform. pfn_notify A callback function that can be registered by the application. This callback function will be used by the OpenCL implementation to report information on errors during context creation as well as errors that occur at runtime in this context. This callback function may be called asynchronously by the OpenCL implementation. It is the application's responsibility to ensure that the callback function is thread-safe. If pfn_notify is NULL, no callback function is registered. The parameters to this callback function are: errinfo is a pointer to an error string. private_info and cb represent a pointer to binary data that is returned by the OpenCL implementation that can be used to log additional information helpful in debugging the error. user_data is a pointer to user supplied data. NOTE: There are a number of cases where error notifications need to be delivered due to an error that occurs outside a context. Such notifications may not be delivered through the pfn_notify callback. Where these notifications go is implementation-defined. user_data Passed as the user_data argument when pfn_notify is called. user_data can be NULL. errcode_ret Returns an appropriate error code. If errcode_ret is NULL, no error code is returned. Notes clCreateContext and clCreateContextFromType perform an implicit retain. This is very helpful for 3rd party libraries, which typically get a context passed to them by the application. However, it is possible that the application may delete the context without informing the library. Allowing functions to attach to (i.e. retain) and release a context solves the problem of a context being used by a library no longer being valid. Errors clCreateContext returns a valid non-zero context and errcode_ret is set to CL_SUCCESS if the context is created successfully. Otherwise, it returns NULL value with the following error values returned in errcode_ret: CL_INVALID_PLATFORM if properties is NULL and no platform could be selected or if platform value specified in properties is not a valid platform. (If the extension cl_khr_gl_sharing is enabled, then this error is replaced with CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR; see below.) CL_INVALID_PROPERTY if context property name in properties is not a supported property name, if the value specified for a supported property name is not valid, or if the same property name is specified more than once. However if the extension cl_khr_gl_sharing is enabled, then CL_INVALID_PROPERTY is returned if an attribute name other than those listed in the table for properties above or if CL_CONTEXT_INTEROP_USER_SYNC is specified in properties. CL_INVALID_PROPERTY if an attribute name other than those specified in table 4.5 or if CL_CONTEXT_INTEROP_USER_SYNC is specified in properties. CL_INVALID_VALUE if devices is NULL; if num_devices is equal to zero; or if pfn_notify is NULL but user_data is not NULL. CL_INVALID_DEVICE if devices contains an invalid device. CL_INVALID_OPERATION if Direct3D 10 interoperability is specified by setting CL_INVALID_D3D10_DEVICE_KHR to a non-NULL value, and interoperability with another graphics API is also specified (if the cl_khr_d3d10_sharing extension is enabled). CL_DEVICE_NOT_AVAILABLE if a device in devices is currently not available even though the device was returned by clGetDeviceIDs. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host. CL_INVALID_D3D10_DEVICE_KHR if the Direct3D 10 device specified for interoperability is not compatible with the devices against which the context is to be created (if the cl_khr_d3d10_sharing extension is enabled). CL_INVALID_D3D10_DEVICE_KHR if the value of the property CL_CONTEXT_D3D10_DEVICE_KHR is non-NULL and does not specify a valid Direct3D 10 device with which the cl_device_ids against which this context is to be created may interoperate (if the cl_khr_d3d10_sharing extension is enabled). CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR when an invalid OpenGL context or share group object handle is specified in properties (only if the cl_khr_gl_sharing extension is enabled). CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR if no OpenGL or OpenGL ES context or share group is specified in the attribute list given to clCreateContext and any of the commands in section 9.7 are called.

A context was specified for a GLX-based OpenGL implementation by setting the attributes CL_GL_CONTEXT_KHR and CL_GLX_DISPLAY_KHR. A context was specified for a WGL-based OpenGL implementation by setting the attributes CL_GL_CONTEXT_KHR and CL_WGL_HDC_KHR. and any of the following conditions hold: The specified display and context attributes do not identify a valid OpenGL or OpenGL ES context. The specified context does not support buffer and renderbuffer objects. The specified context is not compatible with the OpenCL context being created (for example, it exists in a physically distinct address space, such as another hardware device, or does not support sharing data with OpenCL due to implementation restrictions). CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR if a share group was specified for a CGL-based OpenGL implementation by setting the attribute CL_CGL_SHAREGROUP_KHR, and the specified share group does not identify a valid CGL share group object (if the cl_khr_gl_sharing extension is enabled). CL_INVALID_OPERATION if a context was specified as described above and any of the following conditions hold: A context or share group object was specified for one of CGL, EGL, GLX, or WGL and the OpenGL implementation does not support that window-system binding API. More than one of the attributes CL_CGL_SHAREGROUP_KHR, CL_EGL_DISPLAY_KHR, CL_GLX_DISPLAY_KHR, and CL_WGL_HDC_KHR is set to a non-default value. Both of the attributes CL_CGL_SHAREGROUP_KHR and CL_GL_CONTEXT_KHR are set to non-default values.

CL_INVALID_DX9_MEDIA_ADAPTER_KHR if the media adapter specified for interoperability is not compatible with the devices against which the context is to be created (only if the cl_khr_dx9_media_sharing extension is supported).

This keyword is followed by an attribute specification inside double parentheses. The aligned, packed, and endian attribute qualifiers are defined below. aligned (<varname>alignment</varname>) This attribute specifies a minimum alignment for the variable or structure field, measured in bytes. For example, the declaration: int x __attribute__ ((aligned (16))) = 0; causes the compiler to allocate the global variable x on a 16-byte boundary. The alignment value specified must be a power of two. You can also specify the alignment of structure fields. For example, to create double-word aligned int pair, you could write: struct foo { int x[2] __attribute__ ((aligned (8))); }; This is an alternative to creating a union with a double member that forces the union to be double-word aligned. As in the preceding examples, you can explicitly specify the alignment (in bytes) that you wish the compiler to use for a given variable or structure field. Alternatively, you can leave out the alignment factor and just ask the compiler to align a variable or field to the maximum useful alignment for the target machine you are compiling for. For example, you could write: short array[3] __attribute__ ((aligned)); Whenever you leave out the alignment factor in an aligned attribute specification, the OpenCL compiler automatically sets the alignment for the declared variable or field to the largest alignment which is ever used for any data type on the target device you are compiling for. When used on a struct, or struct member, the aligned attribute can only increase the alignment; in order to decrease it, the packed attribute must be specified as well. When used as part of a typedef, the aligned attribute can both increase and decrease alignment, and specifying the packed attribute will generate a warning. Note that the effectiveness of aligned attributes may be limited by inherent limitations of the OpenCL device and compiler. For some devices, the OpenCL compiler may only be able to arrange for variables to be aligned up to a certain maximum alignment. If the OpenCL compiler is only able to align variables up to a maximum of 8 byte alignment, then specifying aligned(16) in an __attribute__ will still only provide you with 8 byte alignment. See your platform-specific documentation for further information. packed The packed attribute specifies that a variable or structure field should have the smallest possible alignment -- one byte for a variable, unless you specify a larger value with the aligned attribute. Here is a structure in which the field x is packed, so that it immediately follows a: struct foo { char a; int x[2] __attribute__ ((packed)); }; An attribute list placed at the beginning of a user-defined type applies to the variable of that type and not the type, while attributes following the type body apply to the type. For example: /* a has alignment of 128 */ __attribute__((aligned(128))) struct A {int i;} a; /* b has alignment of 16 */ __attribute__((aligned(16))) struct B {double d;} __attribute__((aligned(32))) b ; struct A a1; /* a1 has alignment of 4 */ struct B b1; /* b1 has alignment of 32 */ endian (<varname>endiantype</varname>) The endian attribute determines the byte ordering of a variable. endiantype can be set to host indicating the variable uses the endianness of the host processor or can be set to device indicating the variable uses the endianness of the device on which the kernel will be executed. The default is device. For example: float4 *p __attribute__ ((endian(host))); specifies that data stored in memory pointed to by p will be in the host endian format.

Any blocking commands queued in a command-queue and clReleaseCommandQueue perform an implicit flush of the command-queue. These blocking commands are clEnqueueReadBuffer, clEnqueueReadBufferRect, or clEnqueueReadImage with blocking_read set to CL_TRUE; clEnqueueWriteBuffer, clEnqueueWriteBufferRect, or clEnqueueWriteImage with blocking_write set to CL_TRUE; clEnqueueMapBuffer or clEnqueueMapImage with blocking_map set to CL_TRUE; or clWaitForEvents. To use event objects that refer to commands enqueued in a command-queue as event objects to wait on by commands enqueued in a different command-queue, the application must call a clFlush or any blocking commands that perform an implicit flush of the command-queue where the commands that refer to these event objects are enqueued. Errors Returns CL_SUCCESS if the function call was executed successfully. Otherwise, it returns one of the following: CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device.

If the cl_khr_dx9_media_sharing extension is supported, then the following functions are enabled: clGetDeviceIDsFromDX9MediaAdapterKHR clCreateFromDX9MediaSurfaceKHR clEnqueueAcquireDX9MediaSurfacesKHR clEnqueueReleaseDX9MediaSurfacesKHR The OpenCL functions enabled by the cl_khr_dx9_media_sharing extension allow applications to use media surfaces as OpenCL memory objects. This allows efficient sharing of data between OpenCL and selected adapter APIs (only DX9 for now). If this extension is supported, an OpenCL image object can be created from a media surface and the OpenCL API can be used to execute kernels that read and/or write memory objects that are media surfaces. Note that OpenCL memory objects may be created from the adapter media surface if and only if the OpenCL context has been created from that adapter. If this extension is supported by an implementation, the string "cl_khr_dx9_media_sharing" will be present in the CL_PLATFORM_EXTENSIONS or CL_DEVICE_EXTENSIONS string described in the table of allowed values for param_name for clGetDeviceInfo As currently proposed the interfaces for this extension would be provided in cl_dx9_media_sharing.h.

These provide a full set of type conversions between supported types (see Scalar Data Types) except for the following types: bool, half, size_t, ptrdiff_t, intptr_t, uintptr_t, and void. The number of elements in the source and destination vectors must match. The behavior of the conversion may be modified by one or two optional modifiers that specify saturation for out-of-range inputs and rounding behavior. The full form of the scalar convert function is: destType convert_destType<_sat><_roundingMode>(sourceType) The full form of the vector convert function is: destTypen convert_destTypen<_sat><_roundingMode>(sourceTypen) Data Types Conversions are available for the following scalar types: char, uchar, short, ushort, int, uint, long, ulong, float, and built-in vector types derived therefrom. The operand and result type must have the same number of elements. The operand and result type may be the same type in which case the conversion has no effect on the type or value of an expression. Conversions between integer types follow the conversion rules specified in sections 6.3.1.1 and 6.3.1.3 of the C99 specification except for out-of-range behavior and saturated conversions which are described in section 6.2.3.3 below. Rounding Modes Conversions to and from floating-point type shall conform to IEEE-754 rounding rules. Conversions may have an optional rounding mode modifier described in the table below. Modifier Rounding Mode Description _rte Round to nearest even _rtz Round towards zero _rtp Round toward positive infinity _rtn Round toward negative infinity no modifier specified Use the default rounding mode for this destination type, _rtz for conversion to integers or the default rounding mode for conversion to floating-point types. By default, conversions to integer type use the _rtz (round toward zero) rounding mode and conversions to floating-point type use the default rounding mode. The only default floating-point rounding mode supported is round to nearest even, i.e the default rounding mode will be _rte for floating-point types. For conversions to floating-point format, when a finite source value exceeds the maximum representable finite floating-point destination value, the rounding mode will affect whether the result is the maximum finite floating point value or infinity of same sign as the source value, per IEEE-754 rules for rounding. Out-of-Range Behavior and Saturated Conversions When the conversion operand is either greater than the greatest representable destination value or less than the least representable destination value, it is said to be out-of-range. The result of out-of-range conversion is determined by the conversion rules specified by the C99 specification in section 6.3. When converting from a floating-point type to integer type, the behavior is implementation-defined. Conversions to integer type may opt to convert using the optional saturated mode by appending the _sat modifier to the conversion function name. When in saturated mode, values that are outside the representable range shall clamp to the nearest representable value in the destination format. (NaN should be converted to 0). Conversions to floating-point type shall conform to IEEE-754 rounding rules. The _sat modifier may not be used for conversions to floating-point formats. Examples In the following example, convert_int4 converts a uchar4 vector u to an int4 vector c: uchar4 u; int4 c = convert_int4(u); In the following example, convert_int converts a float scalar f to an int scalar i: float f; int i = convert_int(f); Example: short4 s; // negative values clamped to 0 ushort4 u = convert_ushort4_sat( s ); // values > CHAR_MAX converted to CHAR_MAX // values < CHAR_MIN converted to CHAR_MIN char4 c = convert_char4_sat( s ); Example: float4 f; // values implementation defined for // f > INT_MAX, f < INT_MIN or NaN int4 i = convert_int4( f ); // values > INT_MAX clamp to INT_MAX, values < INT_MIN clamp // to INT_MIN. NaN should produce 0. // The _rtz rounding mode is // used to produce the integer values. int4 i2 = convert_int4_sat( f ); // similar to convert_int4, except that // floating-point values are rounded to the nearest // integer instead of truncated int4 i3 = convert_int4_rte( f ); // similar to convert_int4_sat, except that // floating-point values are rounded to the // nearest integer instead of truncated int4 i4 = convert_int4_sat_rte( f ); Example: int4 i; // convert ints to floats using the default rounding mode. float4 f = convert_float4( i ); // convert ints to floats. integer values that cannot // be exactly represented as floats should round up to the // next representable float. float4 f = convert_float4_rtp( i ); Specification OpenCL Specification Also see Scalar Data Types, Vector Data Types khronos-opencl-man-1.0~svn22836/clGetDeviceIDsFromD3D11KHR.xml0000644000175000017500000003021511660441607023424 0ustar mathieumathieu ]> clGetDeviceIDsFromD3D11KHR clGetDeviceIDsFromD3D11KHR 2007-2011 The Khronos Group Inc.

This can be set to CL_ADDRESS_MIRRORED_REPEAT, CL_ADDRESS_REPEAT, CL_ADDRESS_CLAMP_TO_EDGE, CL_ADDRESS_CLAMP, and CL_ADDRESS_NONE. filter_mode Specifies the type of filter that must be applied when reading an image. This can be CL_FILTER_NEAREST or CL_FILTER_LINEAR. errcode_ret Returns an appropriate error code. If errcode_ret is NULL, no error code is returned. Notes A sampler object describes how to sample an image when the image is read in the kernel. The built-in functions to read from an image in a kernel take a sampler as an argument. The sampler arguments to the image read function can be sampler objects created using OpenCL functions and passed as argument values to the kernel or can be samplers declared inside a kernel. In this section we discuss how sampler objects are created using OpenCL functions. For more information about working with samplers, see sampler_t Errors Returns a valid non-zero sampler object and errcode_ret is set to CL_SUCCESS if the sampler object is created successfully. Otherwise, it returns a NULL value with one of the following error values returned in errcode_ret: CL_INVALID_CONTEXT if context is not a valid context. CL_INVALID_VALUE if addressing_mode, filter_mode, or normalized_coords or a combination of these argument values are not valid. CL_INVALID_OPERATION if images are not supported by any device associated with context (i.e. CL_DEVICE_IMAGE_SUPPORT specified in the table of OpenCL Device Queries for clGetDeviceInfo is CL_FALSE).

The specified set of memory objects in mem_objects will be migrated to the OpenCL device associated with command_queue or to the host if the CL_MIGRATE_MEM_OBJECT_HOST has been specified. num_mem_objects The number of memory objects specified in mem_objects. mem_objects A pointer to a list of memory objects. flags A bit-field that is used to specify migration options. The table below describes the possible values for flags. cl_mem_migration flags Description CL_MIGRATE_MEM_OBJECT_HOST This flag indicates that the specified set of memory objects are to be migrated to the host, regardless of the target command-queue. CL_MIGRATE_MEM_OBJECT_- CONTENT_UNDEFINED This flag indicates that the contents of the set of memory objects are undefined after migration. The specified set of memory objects are migrated to the device associated with command_queue without incurring the overhead of migrating their contents. event_wait_list, num_events_in_wait_list Specify events that need to complete before this particular command can be executed. If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. event Returns an event object that identifies this particular command and can be used to query or queue a wait for this particular command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. If the event_wait_list and the event arguments are not NULL, the event argument should not refer to an element of the event_wait_list array. Notes This section describes a mechanism for assigning which device an OpenCL memory object resides. A user may wish to have more explicit control over the location of their memory objects on creation. This could be used to: Ensure that an object is allocated on a specific device prior to usage. Preemptively migrate an object from one device to another. Typically, memory objects are implicitly migrated to a device for which enqueued commands, using the memory object, are targeted. clEnqueueMigrateMemObjects allows this migration to be explicitly performed ahead of the dependent commands. This allows a user to preemptively change the association of a memory object, through regular command queue scheduling, in order to prepare for another upcoming command. This also permits an application to overlap the placement of memory objects with other unrelated operations before these memory objects are needed potentially hiding transfer latencies. Once the event, returned from clEnqueueMigrateMemObjects, has been marked CL_COMPLETE the memory objects specified in mem_objects have been successfully migrated to the device associated with command_queue. The migrated memory object shall remain resident on the device until another command is enqueued that either implicitly or explicitly migrates it away. clEnqueueMigrateMemObjects can also be used to direct the initial placement of a memory object, after creation, possibly avoiding the initial overhead of instantiating the object on the first enqueued command to use it. The user is responsible for managing the event dependencies, associated with this command, in order to avoid overlapping access to memory objects. Improperly specified event dependencies passed to clEnqueueMigrateMemObjects could result in undefined results. Errors clEnqueueMigrateMemObjects returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors: CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command_queue. CL_INVALID_CONTEXT if the context associated with command_queue and memory objects in memobj are not the same or if the context associated with command_queue and events in event_wait_list are not the same. CL_INVALID_MEM_OBJECT if any of the memory objects in mem_objs is not a valid memory object. CL_INVALID_VALUE if num_mem_objects is zero or if mem_objects is NULL. CL_INVALID_VALUE if flags is not 0 or is not any of the values described in the table above. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list > 0, or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects in event_wait_list are not valid events. CL_MEM_OBJECT_ALLOCATION_FAILURE if there is a failure to allocate memory for the specified set of memory objects in mem_objects. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

For the forms that take an image2d_array_t object, use coord.xy to do an element lookup in the 2D image identified by coord.z in the 2D image array specified by image. The samplerless read image functions behave exactly as the corresponding read image functions that take integer coordinates and a sampler with filter mode set to CLK_FILTER_NEAREST, normalized coordinates set to CLK_NORMALIZED_COORDS_FALSE and addressing mode to CLK_ADDRESS_NONE. read_imagei and read_imageui return unnormalized signed integer and unsigned integer values respectively. Each channel will be stored in a 32-bit integer. read_imagei can only be used with image objects created with image_channel_data_type set to one of the following values: CL_SIGNED_INT8, CL_SIGNED_INT16, or CL_SIGNED_INT32. If the image_channel_data_type is not one of the above values, the values returned by read_imagei are undefined. read_imageui can only be used with image objects created with image_channel_data_type set to one of the following values: CL_UNSIGNED_INT8, CL_UNSIGNED_INT16, and CL_UNSIGNED_INT32. If the image_channel_data_type is not one of the above values, the values returned by read_imageui are undefined. The read_imagei and read_imageui calls support a nearest filter only. The filter_mode specified in sampler must be set to CLK_FILTER_NEAREST; otherwise the values returned are undefined. Furthermore, the read_imagei and read_imageui calls that take integer coordinates must use a sampler with normalized coordinates set to CLK_NORMALIZED_COORDS_FALSE and addressing mode set to CLK_ADDRESS_CLAMP_TO_EDGE, CLK_ADDRESS_CLAMP or CLK_ADDRESS_NONE; otherwise the values returned are undefined.

If blocking_read is CL_TRUE i.e. the read command is blocking, clEnqueueReadBuffer does not return until the buffer data has been read and copied into memory pointed to by ptr. If blocking_read is CL_FALSE i.e. the read command is non-blocking, clEnqueueReadBuffer queues a non-blocking read command and returns. The contents of the buffer that ptr points to cannot be used until the read command has completed. The event argument returns an event object which can be used to query the execution status of the read command. When the read command has completed, the contents of the buffer that ptr points to can be used by the application. offset The offset in bytes in the buffer object to read from. size The size in bytes of data being read. ptr The pointer to buffer in host memory where data is to be read into. event_wait_list num_events_in_wait_list event_wait_list and num_events_in_wait_list specify events that need to complete before this particular command can be executed. If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. event Returns an event object that identifies this particular read command and can be used to query or queue a wait for this particular command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. If the event_wait_list and the event arguments are not NULL, the event argument should not refer to an element of the event_wait_list array. Notes Calling clEnqueueReadBuffer to read a region of the buffer object with the ptr argument value set to host_ptr + offset, where host_ptr is a pointer to the memory region specified when the buffer object being read is created with CL_MEM_USE_HOST_PTR, must meet the following requirements in order to avoid undefined behavior: All commands that use this buffer object or a memory object (buffer or image) created from this buffer object have finished execution before the read command begins execution. The buffer object or memory objects created from this buffer object are not mapped. The buffer object or memory objects created from this buffer object are not used by any command-queue until the read command has finished execution. Errors clEnqueueReadBuffer returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors: CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_CONTEXT if the context associated with command_queue and buffer are not the same or if the context associated with command_queue and events in event_wait_list are not the same. CL_INVALID_MEM_OBJECT if buffer is not a valid buffer object. CL_INVALID_VALUE if the region being read specified by (offset, size) is out of bounds or if ptr is a NULL value or if size is 0. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list greater than 0, or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects in event_wait_list are not valid events. CL_MISALIGNED_SUB_BUFFER_OFFSET if buffer is a sub-buffer object and offset specified when the sub-buffer object is created is not aligned to CL_DEVICE_MEM_BASE_ADDR_ALIGN value for device associated with queue. CL_EXEC_STATUS_ERROR_FOR_EVENTS_IN_WAIT_LIST if the read and write operations are blocking and the execution status of any of the events in event_wait_list is a negative integer value. CL_MEM_OBJECT_ALLOCATION_FAILURE if there is a failure to allocate memory for data store associated with buffer. CL_INVALID_OPERATION if clEnqueueReadBuffer is called on buffer which has been created with CL_MEM_HOST_WRITE_ONLY or CL_MEM_HOST_NO_ACCESS. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

The goal of this extension is to provide interoperability between OpenCL and Direct3D 11. This is designed to function analogously to the OpenGL interoperability. If this extension is supported by an implementation, the string cl_khr_d3d11_sharing will be present in the CL_PLATFORM_EXTENSIONS or CL_DEVICE_EXTENSIONS string described in the table of allowed values for param_name for clGetDeviceInfo. As currently proposed the interfaces for this extension would be provided in cl_d3d11.h. This section discusses OpenCL functions that allow applications to use Direct3D 11 resources as OpenCL memory objects. This allows efficient sharing of data between OpenCL and Direct3D 11. The OpenCL API may be used to execute kernels that read and/or write memory objects that are also Direct3D 11 resources. An OpenCL image object may be created from a Direct3D 11 texture resource. An OpenCL buffer object may be created from a Direct3D 11 buffer resource. OpenCL memory objects may be created from Direct3D 11 objects if and only if the OpenCL context has been created from a Direct3D 11 device. An OpenCL memory object created from a Direct3D 11 resource remains valid as long as the corresponding Direct3D 11 resource has not been deleted. If the Direct3D 11 resource is deleted through the Direct3D 11 API, subsequent use of the OpenCL memory object will result in undefined behavior, including but not limited to possible OpenCL errors, data corruption, and program termination. The successful creation of a cl_context against a Direct3D 11 device specified via the context create parameter CL_CONTEXT_D3D11_DEVICE_KHR will increment the internal Direct3D reference count on the specified Direct3D 11 device. The internal Direct3D reference count on that Direct3D 11 device will be decremented when the OpenCL reference count on the returned OpenCL context drops to zero. The OpenCL context and corresponding command-queues are dependent on the existence of the Direct3D 11 device from which the OpenCL context was created. If the Direct3D 11 device is deleted through the Direct3D 11 API, subsequent use of the OpenCL context will result in undefined behavior, including but not limited to possible OpenCL errors, data corruption, and program termination. Properties of Direct3D 11 objects may be queried using clGetMemObjectInfo and clGetImageInfo with param_name CL_MEM_D3D11_RESOURCE_KHR and CL_IMAGE_D3D11_SUBRESOURCE_KHR as described for clGetImageInfo and in the information below about accessing mapped regions of a memory object. khronos-opencl-man-1.0~svn22836/clGetExtensionFunctionAddressForPlatform.xml0000644000175000017500000002257611660441607027156 0ustar mathieumathieu clGetExtensionFunctionAddressForPlatform clGetExtensionFunctionAddressForPlatform 2007-2011 The Khronos Group Inc.

Description The function clGetExtensionFunctionAddressForPlatform returns the address of the extension function named by funcname for a given platform. The pointer returned should be cast to a function pointer type matching the extension function's definition defined in the appropriate extension specification and header file. A return value of NULL indicates that the specified function does not exist for the implementation or platform is not a valid platform. A non-NULL return value for clGetExtensionFunctionAddressForPlatform does not guarantee that an extension function is actually supported by the platform. The application must also make a corresponding query using clGetPlatformInfo (platform, CL_PLATFORM_EXTENSIONS, ... ) or clGetDeviceInfo (device,CL_DEVICE_EXTENSIONS, ... ) to determine if an extension is supported by the OpenCL implementation. clGetExtensionFunctionAddressForPlatform may not be queried for core (non-extension) functions in OpenCL. For functions that are queryable with clGetExtensionFunctionAddressForPlatform, implementations may choose to also export those functions statically from the object libraries implementing those functions. However, portable applications cannot rely on this behavior. Function pointer typedefs must be declared for all extensions that add API entrypoints. These typedefs are a required part of the extension interface, to be provided in an appropriate header (such as cl_ext.h if the extension is an OpenCL extension, or cl_gl_ext.h if the extension is an OpenCL/OpenGL sharing extension). Notes Since there is no way to qualify the query with a device, the function pointer returned must work for all implementations of that extension on different devices for a platform. The behavior of calling a device extension function on a device not supporting that extension is undefined. Example The following convention must be followed for all extensions affecting the host API, where TAG can be KHR, EXT or vendor-specific: #ifndef extension_name #define extension_name 1 // all data typedefs, token #defines, prototypes, and // function pointer typedefs for this extension // function pointer typedefs must use the // following naming convention typedef CL_API_ENTRY return type (CL_API_CALL *clextension_func_nameTAG_fn)(...); #endif // extension_name Consider, for example, the cl_khr_gl_sharing extension.

Perform an async copy of num_gentypes elements from src to dst. The async copy is performed by all work-items in a work-group and this built-in function must therefore be encountered by all work-items in a work-group executing the kernel with the same argument values; otherwise the results are undefined. Returns an event object that can be used by wait_group_events to wait for the async copy to finish. The event argument can also be used to associate the async_work_group_copy with a previous async copy allowing an event to be shared by multiple async copies; otherwise event should be zero. If event argument is non-zero, the event object supplied in event argument will be returned. This function does not perform any implicit synchronization of source data such as using a barrier before performing the copy. Notes The generic type name gentype indicates the built-in data types char, char{2|3|4|8|16}, uchar, uchar{2|3|4|8|16}, short, short{2|3|4|8|16}, ushort, ushort{2|3|4|8|16}, int, int{2|3|4|8|16}, uint, uint{2|3|4|8|16}, long, long{2|3|4|8|16}, ulong, ulong{2|3|4|8|16} or float, float{2|3|4|8|16} as the type for the arguments unless otherwise stated. Optionally, generic type name gentype may indicate double and double{2|3|4|8|16} as arguments and return values. If extended with cl_khr_fp16, generic type name gentype may indicate half and half{2|3|4|8|16} as arguments and return values. async_work_group_copy and async_work_group_strided_copy for 3-component vector types behave as async_work_group_copy and async_work_group_strided_copy respectively for 4-component vector types.

The following rules apply: Arguments to __kernel functions declared in a program that are pointers must be declared with the __global, __constant, or __local qualifier. A pointer declared with the __constant, __local, or __global qualifier can only be assigned to a pointer declared with the __constant, __local, or __global qualifier respectively. Pointers to functions are not allowed. Arguments to __kernel functions in a program cannot be declared as a pointer to a pointer(s). Variables inside a function or arguments to non-kernel functions in a program can be declared as a pointer to a pointer(s). An image type ( image2d_t, image3d_t, image2d_array_t, image1d_t, image1d_buffer_t, or image1d_array_t) can only be used as the type of a function argument. An image function argument cannot be modified. Elements of an image can only be accessed using the Built-in Image Functions. An image type cannot be used to declare a variable, a structure or union field, an array of images, a pointer to an image, or the return type of a function. An image type cannot be used with the __private, __local and __constant address space qualifiers. The image3d_t type cannot be used with the __write_only access qualifier unless the cl_khr_3d_image_writes extension is enabled. An image type cannot be used with the __read_write access qualifer which is reserved for future use. The sampler type (sampler_t) can only be used as the type of a function argument or a variable declared in the program scope or the outermost scope of a kernel function. The behavior of a sampler variable declared in a non-outermost scope of a kernel function is implementation-defined. A sampler argument or variable cannot be modified. The sampler type cannot be used to declare a structure or union field, an array of samplers, a ponter to a sampler, or the return type of a function. The sampler type cannot be used with the __local and __global address space qualifiers. Bit-fields struct members are currently not supported. Variable length arrays and structures with flexible (or unsized) arrays are not supported. Variadic macros and functions are not supported. The library functions defined in the C99 standard headers assert.h, ctype.h, complex.h, errno.h, fenv.h, float.h, inttypes.h, limits.h, locale.h, setjmp.h, signal.h, stdarg.h, stdio.h, stdlib.h, string.h, tgmath.h, time.h, wchar.h, and wctype.h are not available and cannot be included by a program. The auto and register storage-class specifiers are not supported. Recursion is not supported. The function using the __kernel qualifier can only have return type void in the source code. Arguments to kernel functions in a program cannot be declared with the built-in scalar types bool, half, size_t, ptrdiff_t, intptr_t, and uintptr_t, or a struct and/or union that contain fields declared to be one of these built-in scalar types. The size in bytes of these types except half are implementation-defined and in addition can also be different for the OpenCL device and the host processor making it difficult to allocate buffer objects to be passed as arguments to a kernel declared as pointer to these types. half is not supported as half can be used as a storage format only (unless the cl_khr_fp16 extension is supported) and is not a data type on which floating-point arithmetic can be performed. Whether or not irreducible control flow is illegal is implementation defined. Arguments to kernel functions in a program cannot be declared to be of type event_t. Elements of a struct or union must belong to the same address space. Declaring a struct or union whose elements are in different address spaces is illegal. Arguments to kernel functions that are declared to be a struct or union do not allow OpenCL objects to be passed as elements of the struct or union. The type qualifiers const, restrict, and volatile as defined by the C99 specification are supported. These qualifiers cannot be used with image2d_t, image3d_t, image2d_array_t, image1d_t, image1d_buffer_t, and image1d_array_t types. Types other than pointer types shall not use the restrict qualifier. The event type (event_t) cannot be used as the type of a kernel function argument. The event type cannot be used to declare a program scope variable. The event type cannot be used to declare a structure or union field. The event type cannot be used with the __local, __constant, and __global address space qualifiers.

The command execution callback value for which a callback can be registered is CL_SUBMITTED, CL_RUNNING, or CL_COMPLETE. There is no guarantee that the callback functions registered for various execution status values for an event will be called in the exact order that the execution status of a command changes. Furthermore, it should be noted that receiving a call back for an event with a status other than CL_COMPLETE, in no way implies that the memory model or execution model as defined by the OpenCL specification has changed. For example, it is not valid to assume that a corresponding memory transfer has completed unless the event is in a state CL_COMPLETE. The callback function registered for a command_exec_callback_type value of CL_COMPLETE will be called when the command has completed successfully or is abnormally terminated. pfn_event_notify The event callback function that can be registered by the application. This callback function may be called asynchronously by the OpenCL implementation. It is the application's responsibility to ensure that the callback function is thread-safe. The parameters to this callback function are: event is the event object for which the callback function is invoked. event_command_exec_status represents the execution status of command for which this callback function is invoked. See the table of values for param_value for clGetEventInfo for the command execution status values. If the callback is called as the result of the command associated with event being abnormally terminated, an appropriate error code for the error that caused the termination will be passed to event_command_exec_status instead. user_data is a pointer to user supplied data. user_data Will be passed as the user_data argument when pfn_notify is called. user_data can be NULL. Notes The registered callback function will be called when the execution status of command associated with event changes to an execution status equal to or past the status specified by command_exec_status. Each call to clSetEventCallback registers the specified user callback function on a callback stack associated with event. The order in which the registered user callback functions are called is undefined. All callbacks registered for an event object must be called. All enqueued callbacks shall be called before the event object is destroyed. Callbacks must return promptly. The behavior of calling expensive system routines, OpenCL API calls to create contexts or command-queues, or blocking OpenCL operations from the following list below, in a callback is undefined. clFinish clWaitForEvents blocking calls to clEnqueueReadBuffer, clEnqueueReadBufferRect, clEnqueueWriteBuffer, and clEnqueueWriteBufferRect blocking calls to clEnqueueReadImage and clEnqueueWriteImage blocking calls to clEnqueueMapBuffer and clEnqueueMapImage blocking calls to clBuildProgram, clCompileProgram, or clLinkProgram. If an application needs to wait for completion of a routine from the above list in a callback, please use the non-blocking form of the function, and assign a completion callback to it to do the remainder of your work. Note that when a callback (or other code) enqueues commands to a command-queue, the commands are not required to begin execution until the queue is flushed. In standard usage, blocking enqueue calls serve this role by implicitly flushing the queue. Since blocking calls are not permitted in callbacks, those callbacks that enqueue commands on a command queue should either call clFlush on the queue before returning or arrange for clFlush to be called later on another thread. Errors Returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors: CL_INVALID_EVENT if event is not a valid event object. CL_INVALID_VALUE if pfn_event_notify is NULL or if command_exec_callback_type is not CL_COMPLETE. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

If blocking_write is CL_TRUE, the OpenCL implementation copies the data referred to by ptr and enqueues the write operation in the command-queue. The memory pointed to by ptr can be reused by the application after the clEnqueueWriteBuffer call returns. If blocking_write is CL_FALSE, the OpenCL implementation will use ptr to perform a nonblocking write. As the write is non-blocking the implementation can return immediately. The memory pointed to by ptr cannot be reused by the application after the call returns. The event argument returns an event object which can be used to query the execution status of the write command. When the write command has completed, the memory pointed to by ptr can then be reused by the application. offset The offset in bytes in the buffer object to write to. size The size in bytes of data being written. ptr The pointer to buffer in host memory where data is to be written from. event_wait_list num_events_in_wait_list event_wait_list and num_events_in_wait_list specify events that need to complete before this particular command can be executed. If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. event Returns an event object that identifies this particular write command and can be used to query or queue a wait for this particular command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. Notes Calling clEnqueueWriteBuffer to update the latest bits in a region of the buffer object with the ptr argument value set to host_ptr + offset, where host_ptr is a pointer to the memory region specified when the buffer object being written is created with CL_MEM_USE_HOST_PTR, must meet the following requirements in order to avoid undefined behavior: The host memory region given by (host_ptr + offset, cb) contains the latest bits when the enqueued write command begins execution. The buffer object or memory objects created from this buffer object are not mapped. The buffer object or memory objects created from this buffer object are not used by any command-queue until the read command has finished execution. Errors clEnqueueWriteBuffer returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors: CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_CONTEXT if the context associated with command_queue and buffer are not the same or if the context associated with command_queue and events in event_wait_list are not the same. CL_INVALID_MEM_OBJECT if buffer is not a valid buffer object. CL_INVALID_VALUE if the region being written specified by (offset, size) is out of bounds or if ptr is a NULL value or if size is 0. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list greater than 0, or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects in event_wait_list are not valid events. CL_MISALIGNED_SUB_BUFFER_OFFSET if buffer is a sub-buffer object and offset specified when the sub-buffer object is created is not aligned to CL_DEVICE_MEM_BASE_ADDR_ALIGN value for device associated with queue. CL_EXEC_STATUS_ERROR_FOR_EVENTS_IN_WAIT_LIST if the read and write operations are blocking and the execution status of any of the events in event_wait_list is a negative integer value. CL_MEM_OBJECT_ALLOCATION_FAILURE if there is a failure to allocate memory for data store associated with buffer. CL_INVALID_OPERATION if clEnqueueWriteBuffer is called on buffer which has been created with CL_MEM_HOST_READ_ONLY or CL_MEM_HOST_NO_ACCESS. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device.

The maximum error is implementation-defined. Notes This built-in math function takes scalar or vector arguments. The generic type name gentype is used to indicate that the function can take float, float2, float4, float8, or float16 as the type for the arguments. For any specific use of these function, the actual type has to be the same for all arguments and the return type. Functions with the half_ prefix are implemented with a minimum of 10-bits of accuracy i.e. an ULP value less than or equal to 8192 ulp. Functions with the native__ prefix may map to one or more native device instructions and will typically have better performance compared to the corresponding functions (without the native__ prefix). The accuracy (and in some cases the input range(s)) of these functions is implementation-defined. The vector versions of the math functions operate component-wise. The description is per-component. The built-in math functions are not affected by the prevailing rounding mode in the calling environment, and always return the same value as they would if called with the round to nearest even rounding mode.

If the event_wait_list and the event arguments are not NULL, the event argument should not refer to an element of the event_wait_list array Notes The Direct3D 11 objects are released by the OpenCL context associated with command_queue. OpenCL memory objects created from Direct3D 11 resources which have been acquired by OpenCL must be released by OpenCL before they may be accessed by Direct3D 11. Accessing a Direct3D 11 resource while its corresponding OpenCL memory object is acquired is in error and will result in undefined behavior, including but not limited to possible OpenCL errors, data corruption, and program termination.

Preprocessor Options These options control the OpenCL C preprocessor which is run on each program source before actual compilation. -D options are processed in the order they are given in the options argument to clBuildProgram or or clCompileProgram. -D name Predefine name as a macro, with definition 1. -D name=definition The contents of definition are tokenized and processed as if they appeared during translation phase three in a `#define' directive. In particular, the definition will be truncated by embedded newline characters. -I dir Add the directory dir to the list of directories to be searched for header files. Math Intrinsics Options These options control compiler behavior regarding floating-point arithmetic. These options trade off between speed and correctness. -cl-single-precision-constant Treat double precision floating-point constant as single precision constant. -cl-denorms-are-zero This option controls how single precision and double precision denormalized numbers are handled. If specified as a build option, the single precision denormalized numbers may be flushed to zero; double precision denormalized numbers may also be flushed to zero if the optional extension for double precsion is supported. This is intended to be a performance hint and the OpenCL compiler can choose not to flush denorms to zero if the device supports single precision (or double precision) denormalized numbers. This option is ignored for single precision numbers if the device does not support single precision denormalized numbers i.e. CL_FP_DENORM bit is not set in CL_DEVICE_SINGLE_FP_CONFIG. This option is ignored for double precision numbers if the device does not support double precision or if it does support double precison but CL_FP_DENORM bit is not set in CL_DEVICE_DOUBLE_FP_CONFIG. This flag only applies for scalar and vector single precision floating-point variables and computations on these floating-point variables inside a program. It does not apply to reading from or writing to image objects. -cl-fp32-correctly-rounded-divide-sqrt The -cl-fp32-correctly-rounded-divide-sqrt build option to clBuildProgram or clCompileProgram allows an application to specify that single precision floating-point divide (x/y and 1/x) and sqrt used in the program source are correctly rounded. If this build option is not specified, the minimum numerical accuracy of single precision floating-point divide and sqrt are as defined in section 7.4 of the OpenCL specification. This build option can only be specified if the CL_FP_CORRECTLY_ROUNDED_DIVIDE_SQRT is set in CL_DEVICE_SINGLE_FP_CONFIG (as defined in in the table of allowed values for param_name for clGetDeviceInfo) for devices that the program is being build. clBuildProgram or clCompileProgram will fail to compile the program for a device if the -cl-fp32-correctly-rounded-divide-sqrt option is specified and CL_FP_CORRECTLY_ROUNDED_DIVIDE_SQRT is not set for the device. Optimization Options These options control various sorts of optimizations. Turning on optimization flags makes the compiler attempt to improve the performance and/or code size at the expense of compilation time and possibly the ability to debug the program. -cl-opt-disable This option disables all optimizations. The default is optimizations are enabled. The following options control compiler behavior regarding floating-point arithmetic. These options trade off between performance and correctness and must be specifically enabled. These options are not turned on by default since it can result in incorrect output for programs which depend on an exact implementation of IEEE 754 rules/specifications for math functions. -cl-mad-enable Allow a * b + c to be replaced by a mad. The mad computes a * b + c with reduced accuracy. For example, some OpenCL devices implement mad as truncate the result of a * b before adding it to c. -cl-no-signed-zeros Allow optimizations for floating-point arithmetic that ignore the signedness of zero. IEEE 754 arithmetic specifies the distinct behavior of +0.0 and -0.0 values, which then prohibits simplification of expressions such as x+0.0 or 0.0*x (even with -clfinite-math only). This option implies that the sign of a zero result isn't significant. -cl-unsafe-math-optimizations Allow optimizations for floating-point arithmetic that (a) assume that arguments and results are valid, (b) may violate IEEE 754 standard and (c) may violate the OpenCL numerical compliance requirements as defined in section 7.4 for single precision and double precision floating-point, and edge case behavior in section 7.5. This option includes the -cl-no-signed-zeros and -cl-mad-enable options. -cl-finite-math-only Allow optimizations for floating-point arithmetic that assume that arguments and results are not NaNs or ±∞. This option may violate the OpenCL numerical compliance requirements defined in section 7.4 for single precision and double precision floating point, and edge case behavior in section 7.5. -cl-fast-relaxed-math Sets the optimization options -cl-finite-math-only and -cl-unsafe-math-optimizations. This allows optimizations for floating-point arithmetic that may violate the IEEE 754 standard and the OpenCL numerical compliance requirements defined in the specification in section 7.4 for single-precision and double precision floating-point, and edge case behavior in section 7.5. This option causes the preprocessor macro __FAST_RELAXED_MATH__ to be defined in the OpenCL program. Options to Request or Suppress Warnings Warnings are diagnostic messages that report constructions which are not inherently erroneous but which are risky or suggest there may have been an error. The following languageindependent options do not enable specific warnings but control the kinds of diagnostics produced by the OpenCL compiler. -w Inhibit all warning messages. -Werror Make all warnings into errors. Options Controlling the OpenCL C Version The following option controls the version of OpenCL C that the compiler accepts. -cl-std= Determine the OpenCL C language version to use. A value for this option must be provided. Valid values are: CL1.1 - Support all OpenCL C programs that use the OpenCL C language features defined in section 6 of the OpenCL 1.1 specification. CL1.2 – Support all OpenCL C programs that use the OpenCL C language features defined in section 6 of the OpenCL 1.2 specification. Calls to clBuildProgram or clCompileProgram with the -cl-std=CL1.1 option will fail to compile the program for any devices with CL_DEVICE_OPENCL_C_VERSION = OpenCL C 1.0. Calls to clBuildProgram or clCompileProgram with the -cl-std=CL1.2 option will fail to compile the program for any devices with CL_DEVICE_OPENCL_C_VERSION = OpenCL C 1.0 or OpenCL C 1.1. If the -cl-std build option is not specified, the CL_DEVICE_OPENCL_C_VERSION is used to select the version of OpenCL C to be used when compiling the program for each device. Options for Querying Kernel Argument Information -cl-kernel-arg-info This option allows the compiler to store information about the arguments of a kernel(s) in the program executable. The argument information stored includes the argument name, its type, the address and access qualifiers used. Refer to description of clGetKernelArgInfo on how to query this information. Linker Options This specification defines a standard set of linker options that must be supported by the OpenCL C compiler when linking compiled programs online or offline. These linker options are categorized as library linking options and program linking options. These may be extended by a set of vendor- or platform-specific options. Library Linking Options The following options can be specified when creating a library of compiled binaries. -create-library Create a library of compiled binaries specified in input_programs argument to clLinkProgram. -enable-link-options Allows the linker to modify the library behavior based on one or more link options (described in Program Linking Options, below) when this library is linked with a program executable. This option must be specified with the –create-library option. Program Linking Options The following options can be specified when linking a program executable. -cl-denorms-are-zero -cl-no-signed-zeroes -cl-unsafe-math-optimizations -cl-finite-math-only -cl-fast-relaxed-mat The linker may apply these options to all compiled program objects specified to clLinkProgram. The linker may apply these options only to libraries which were created with the –enable-link-option. Separate Compilation and Linking of Programs OpenCL 1.2 extends how programs are compiled and linked to support the following: Separate compilation and link stages. Program sources can be compiled to generate a compiled binary object and linked in a separate stage with other compiled program objects to the program exectuable. Embedded headers. In OpenCL 1.0 and 1.1, the –I build option could be used to specify the list of directories to be searched for headers files that are included by a program source(s). OpenCL 1.2 extends this by allowing the header sources to come from program objects instead of just header files. Libraries. The linker can be used to link compiled objects and libraries into a program executable or to create a library of compiled binarie khronos-opencl-man-1.0~svn22836/clSetKernelArg.xml0000644000175000017500000004574311660441607021701 0ustar mathieumathieu clSetKernelArg clSetKernelArg 2007-2011 The Khronos Group Inc.

Arguments to the kernel are referred by indices that go from 0 for the leftmost argument to n - 1, where n is the total number of arguments declared by a kernel. arg_value A pointer to data that should be used as the argument value for argument specified by arg_index. The argument data pointed to by arg_value is copied and the arg_value pointer can therefore be reused by the application after clSetKernelArg returns. The argument value specified is the value used by all API calls that enqueue kernel (clEnqueueNDRangeKernel and clEnqueueTask) until the argument value is changed by a call to clSetKernelArg for kernel. If the argument is a memory object (buffer, image or image array), the arg_value entry will be a pointer to the appropriate buffer, image or image array object. The memory object must be created with the context associated with the kernel object. If the argument is a buffer object, the arg_value pointer can be NULL or point to a NULL value in which case a NULL value will be used as the value for the argument declared as a pointer to __global or __constant memory in the kernel. If the argument is declared with the __local qualifier, the arg_value entry must be NULL. If the argument is of type sampler_t, the arg_value entry must be a pointer to the sampler object. If the argument is declared to be a pointer of a built-in scalar or vector type, or a user defined structure type in the global or constant address space, the memory object specified as argument value must be a buffer object (or NULL). If the argument is declared with the __constant qualifier, the size in bytes of the memory object cannot exceed CL_DEVICE_MAX_CONSTANT_BUFFER_SIZE and the number of arguments declared as pointers to __constant memory cannot exceed CL_DEVICE_MAX_CONSTANT_ARGS. The memory object specified as argument value must be a 2D image object if the argument is declared to be of type image2d_t. The memory object specified as argument value must be a 3D image object if argument is declared to be of type image3d_t. The memory object specified as argument value must be a 1D image object if the argument is declared to be of type image1d_t. The memory object specified as argument value must be a 1D image buffer object if the argument is declared to be of type image1d_buffer_t. The memory object specified as argument value must be a 1D image array object if argument is declared to be of type image1d_array_t. The memory object specified as argument value must be a 2D image array object if argument is declared to be of type image2d_array_t. For all other kernel arguments, the arg_value entry must be a pointer to the actual data to be used as argument value. arg_size Specifies the size of the argument value. If the argument is a memory object, the size is the size of the buffer or image object type. For arguments declared with the __local qualifier, the size specified will be the size in bytes of the buffer that must be allocated for the __local argument. If the argument is of type sampler_t, the arg_size value must be equal to sizeof(cl_sampler). For all other arguments, the size will be the size of argument type. Notes A kernel object does not update the reference count for objects such as memory, sampler objects specified as argument values by clSetKernelArg. Users may not rely on a kernel object to retain objects specified as argument values to the kernel. Implementations shall not allow cl_kernel objects to hold reference counts to cl_kernel arguments, because no mechanism is provided for the user to tell the kernel to release that ownership right. If the kernel holds ownership rights on kernel args, that would make it impossible for the user to tell with certainty when he may safely release user allocated resources associated with OpenCL objects such as the cl_mem backing store used with CL_MEM_USE_HOST_PTR. An OpenCL API call is considered to be thread-safe if the internal state as managed by OpenCL remains consistent when called simultaneously by multiple host threads. OpenCL API calls that are thread-safe allow an application to call these functions in multiple host threads without having to implement mutual exclusion across these host threads i.e. they are also re-entrant-safe. All OpenCL API calls are thread-safe except clSetKernelArg. clSetKernelArg is safe to call from any host thread, and is safe to call re-entrantly so long as concurrent calls operate on different cl_kernel objects. However, the behavior of the cl_kernel object is undefined if clSetKernelArg is called from multiple host threads on the same cl_kernel object at the same time. Please note that there are additional limitations as to which OpenCL APIs may be called from OpenCL callback functions -- please see section 5.9. There is an inherent race condition in the design of OpenCL that occurs between setting a kernel argument and using the kernel with clEnqueueNDRangeKernel or clEnqueueTask. Another host thread might change the kernel arguments between when a host thread sets the kernel arguments and then enqueues the kernel, causing the wrong kernel arguments to be enqueued. Rather than attempt to share cl_kernel objects among multiple host threads, applications are strongly encouraged to make additional cl_kernel objects for kernel functions for each host thread. Errors clSetKernelArg returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors: CL_INVALID_KERNEL if kernel is not a valid kernel object. CL_INVALID_ARG_INDEX if arg_index is not a valid argument index. CL_INVALID_ARG_VALUE if arg_value specified is not a valid value. CL_INVALID_MEM_OBJECT for an argument declared to be a memory object when the specified arg_value is not a valid memory object. CL_INVALID_SAMPLER for an argument declared to be of type sampler_t when the specified arg_value is not a valid sampler object. CL_INVALID_ARG_SIZE if arg_size does not match the size of the data type for an argument that is not a memory object or if the argument is a memory object and arg_size != sizeof(cl_mem) or if arg_size is zero and the argument is declared with the __local qualifier or if the argument is a sampler and arg_size != sizeof(cl_sampler). CL_INVALID_ARG_VALUE if the argument is an image declared with the read_only qualifier and arg_value refers to an image object created with cl_mem_flags of CL_MEM_WRITE or if the image argument is declared with the write_only qualifier and arg_value refers to an image object created with cl_mem_flags of CL_MEM_READ. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host. Example kernel void image_filter (int n, int m, __constant float *filter_weights, __read_only image2d_t src_image, __write_only image2d_t dst_image) { ... } Argument index values for image_filter will be 0 for n, 1 for m, 2 for filter_weights, 3 for src_image and 4 for dst_image.

Refer to the table of allowed values for flags for clCreateBuffer. Only CL_MEM_READ_ONLY, CL_MEM_WRITE_ONLY, and CL_MEM_READ_WRITE values specified in the table of allowed values for flags for clCreateBuffer can be used. adapter_type A value from enumeration of supported adapters described in the table of cl_dx9_media_adapter_type_khr values for clGetDeviceIDsFromDX9MediaAdapterKHR. The type of surface_info is determined by the adapter type. The implementation does not need to support all adapter types. This approach provides flexibility to support additional adapter types in the future. Supported adapter types are CL_ADAPTER_D3D9_KHR, CL_ADAPTER_D3D9EX_KHR, and CL_ADAPTER_DXVA_KHR. If adapter_type is CL_ADAPTER_D3D9_KHR, CL_ADAPTER_D3D9EX_KHR, or CL_ADAPTER_DXVA_KHR, the surface_info points to the following structure: typedef struct _cl_dx9_surface_info_khr { IDirect3DSurface9 *resource; HANDLE shared_handle; } cl_dx9_surface_info_khr; For D3D9 surfaces, we need both the handle to the resource and the resource itself to have a sufficient amount of information to eliminate a copy of the surface for sharing in cases where this is possible. Elimination of the copy is driver dependent. shared_handle may be NULL and this may result in sub-optimal performance. surface_info A pointer to one of the structures defined in the adapter_type description above passed in as a void *. plane The plane of resource to share for planar surface formats. For planar formats, we use the plane parameter to obtain a handle to thie specific plane (Y, U or V for example). For nonplanar formats used by media, plane must be 0. errcode_ret An appropriate error code. If errcode_ret is NULL, no error code is returned. Notes The width and height of the returned OpenCL 2D image object are determined by the width and height of the plane of resource. The channel type and order of the returned image object is determined by the format and plane of resource and are described in tables 9.10.3 and 9.10.4. This call will increment the internal media surface count on resource. The internal media surface reference count on resource will be decremented when the OpenCL reference count on the returned OpenCL memory object drops to zero. DX9 Media Surface Sharing &mediaSurfaceFormatsInc; &accessMappedInc; Errors Returns CL_SUCCESS returns a valid non-zero 2D image object and errcode_ret is set to CL_SUCCESS if the 2D image object is created successfully. Otherwise, it returns a NULL value with one of the following error values returned in errcode_ret: CL_INVALID_CONTEXT if context is not a valid context. CL_INVALID_VALUE if values specified in flags are not valid or if plane is not a valid plane of resource specified in surface_info.. CL_INVALID_DX9_MEDIA_SURFACE_KHR if resource specified in surface_info is not a valid resource or is not associated with adapter_type (e.g., adapter_type is set to CL_ADAPTER_D3D9_KHR and resource is not a Direct3D 9 surface created in D3DPOOL_DEFAULT). CL_INVALID_DX9_MEDIA_SURFACE_KHR if shared_handle specified in surface_info is not NULL or a valid handle value. CL_INVALID_IMAGE_FORMAT_DESCRIPTOR if the texture format of resource is not listed in tables 9.10.3 and 9.10.4. CL_INVALID_OPERATION if there are no devices in context that support adapter_type. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. event Returns n event object that identifies this particular command and can be used to query or queue a wait for this particular command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. Notes The Direct3D 10 objects are acquired by the OpenCL context associated with command-queue and can therefore be used by all command-queues associated with the OpenCL context. OpenCL memory objects created from Direct3D 10 resources must be acquired before they can be used by any OpenCL commands queued to a command-queue. If an OpenCL memory object created from a Direct3D 10 resource is used while it is not currently acquired by OpenCL, the call attempting to use that OpenCL memory object will return CL_D3D10_RESOURCE_NOT_ACQUIRED_KHR. If CL_CONTEXT_INTEROP_USER_SYNC is not specified as CL_TRUE during context creation, clEnqueueAcquireD3D10ObjectsKHR provides the synchronization guarantee that any Direct3D 10 calls involving the interop device(s) used in the OpenCL context made before clEnqueueAcquireD3D10ObjectsKHR is called will complete executing before event reports completion and before the execution of any subsequent OpenCL work issued in command_queue begins. If the context was created with properties specifying CL_CONTEXT_INTEROP_USER_SYNC as CL_TRUE, the user is responsible for guaranteeing that any Direct3D 10 calls involving the interop device(s) used in the OpenCL context made before clEnqueueAcquireD3D10ObjectsKHR is called have completed before calling clEnqueueAcquireD3D10ObjectsKHR. &sharingD3D10Inc; Errors Returns CL_SUCCESS returns CL_SUCCESS if the function is executed successfully. If num_objects is 0 and mem_objects is NULL then the function does nothing and returns CL_SUCCESS. Otherwise it returns one of the following errors: CL_INVALID_VALUE if num_objects is zero and mem_objects is not a NULL value or if num_objects > 0 and mem_objects is NULL. CL_INVALID_MEM_OBJECT if memory objects in mem_objects are not valid OpenCL memory objects or if memory objects in mem_objects have not been created from Direct3D 10 resources. CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_CONTEXT if context associated with command_queue was not created from an Direct3D 10 context. CL_D3D10_RESOURCE_ALREADY_ACQUIRED_KHR if memory objects in mem_objects is not have previously been acquired using clEnqueueAcquireD3D10ObjectsKHR but have not been released using clEnqueueReleaseD3D10ObjectsKHR. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_event_in_wait_list > 0, or event_wait_list is not NULL and num_event_in_wait_list is 0, or if event objects in event_wait_list are not valid events.

The built-in math functions are not affected by the prevailing rounding mode in the calling environment, and always return the same value as they would if called with the round to nearest even rounding mode. The built-in math functions take scalar or vector arguments. The generic type name gentype is used to indicate that the function can take float, float2, float3, float4, float8, or float16 as the type for the arguments. For any specific use of these function, the actual type has to be the same for all arguments and the return type.

For a 2D image and image array, the image width must be ≤ CL_DEVICE_IMAGE2D_MAX_WIDTH. For a 3D image, the image width must be ≤ CL_DEVICE_IMAGE3D_MAX_WIDTH. For a 1D image buffer, the image width must be ≤ CL_DEVICE_IMAGE_MAX_BUFFER_SIZE. For a 1D image and 1D image array, the image width must be ≤ CL_DEVICE_IMAGE2D_MAX_WIDTH. image_height The height of the image in pixels. This is only used if the image is a 2D, 3D or 2D image array. For a 2D image or image array, the image height must be ≤ CL_DEVICE_IMAGE2D_MAX_HEIGHT. For a 3D image, the image height must be ≤ CL_DEVICE_IMAGE3D_MAX_HEIGHT. image_depth The depth of the image in pixels. This is only used if the image is a 3D image and must be a value ≥ 1 and ≤ CL_DEVICE_IMAGE3D_MAX_DEPTH. image_array_size The number of images in the image array. This is only used if the image is a 1D or 2D image array. The values for image_array_size, if specified, must be a value ≥ 1 and ≤ CL_DEVICE_IMAGE_MAX_ARRAY_SIZE. Note that reading and writing 2D image arrays from a kernel with image_array_size = 1 may be lower performance than 2D images. image_row_pitch The scan-line pitch in bytes. This must be 0 if host_ptr is NULL and can be either 0 or ≥ image_width * size of element in bytes if host_ptr is not NULL. If host_ptr is not NULL and image_row_pitch = 0, image_row_pitch is calculated as image_width * size of element in bytes. If image_row_pitch is not 0, it must be a multiple of the image element size in bytes. image_slice_pitch The size in bytes of each 2D slice in the 3D image or the size in bytes of each image in a 1D or 2D image array. This must be 0 if host_ptr is NULL. If host_ptr is not NULL, image_slice_pitch can be either 0 or ≥ image_row_pitch * image_height for a 2D image array or 3D image and can be either 0 or ≥ image_row_pitch for a 1D image array. If host_ptr is not NULL and image_slice_pitch = 0, image_slice_pitch is calculated as image_row_pitch * image_height for a 2D image array or 3D image and image_row_pitch for a 1D image array. If image_slice_pitch is not 0, it must be a multiple of the image_row_pitch. num_mip_level, num_samples Must be 0. buffer Refers to a valid buffer memory object if image_type is CL_MEM_OBJECT_IMAGE1D_BUFFER. Otherwise it must be NULL. For a 1D image buffer object, the image pixels are taken from the buffer object's data store. When the contents of a buffer object's data store are modified, those changes are reflected in the contents of the 1D image buffer object and vice-versa at corresponding sychronization points. The image_width * size of element in bytes must be ≤ size of buffer object data store. Note Concurrent reading from, writing to and copying between both a buffer object and 1D image buffer object associated with the buffer object is undefined. Only reading from both a buffer object and 1D image buffer object associated with the buffer object is defined.

The contents of the region of a memory object and associated memory objects (sub-buffer objects or 1D image buffer objects that overlap this region) mapped for writing (i.e. CL_MAP_WRITE or CL_MAP_WRITE_INVALIDATE_REGION is set in map_flags argument to clEnqueueMapBuffer or clEnqueueMapImage) are considered to be undefined until this region is unmapped. Multiple commands in command-queues can map a region or overlapping regions of a memory object and associated memory objects (sub-buffer objects or 1D image buffer objects that overlap this region) for reading (i.e. map_flags = CL_MAP_READ). The contents of the regions of a memory object mapped for reading can also be read by kernels and other OpenCL commands (such as clEnqueueCopyBuffer) executing on a device(s). Mapping (and unmapping) overlapped regions in a memory object and/or associated memory objects (sub-buffer objects or 1D image buffer objects that overlap this region) for writing is an error and will result in CL_INVALID_OPERATION error returned by clEnqueueMapBuffer or clEnqueueMapImage. If a memory object is currently mapped for writing, the application must ensure that the memory object is unmapped before any enqueued kernels or commands that read from or write to this memory object or any of its associated memory objects (sub-buffer or 1D image buffer objects) or its parent object (if the memory object is a sub-buffer or 1D image buffer object) begin execution; otherwise the behavior is undefined. If a memory object is currently mapped for reading, the application must ensure that the memory object is unmapped before any enqueued kernels or commands that write to this memory object or any of its associated memory objects (sub-buffer or 1D image buffer objects) or its parent object (if the memory object is a sub-buffer or 1D image buffer object) begin execution; otherwise the behavior is undefined. Accessing the contents of the memory region referred to by the mapped pointer that has been unmapped is undefined. The mapped pointer returned by clEnqueueMapBuffer or clEnqueueMapImage can be used as ptr argument value to clEnqueueReadBuffer, clEnqueueWriteBuffer, clEnqueueReadBufferRect, clEnqueueWriteBufferRect, clEnqueueReadImage, and clEnqueueWriteImage, provided the rules described above are adhered to. khronos-opencl-man-1.0~svn22836/as_typen.xml0000644000175000017500000002174311660441607020650 0ustar mathieumathieu Reinterpreting Types, as_typen(), as_type() Reinterpreting Types Using as_type() and as_typen() 2007-2011 The Khronos Group Inc.

When the operand and result type contain the same number of elements, the bits in the operand shall be returned directly without modification as the new type. The usual type promotion for function arguments shall not be performed. For example, as_float(0x3f800000) returns 1.0f, which is the value that the bit pattern 0x3f800000 has if viewed as an IEEE-754 single precision value. When the operand and result type contain a different number of elements, the result shall be implementation-defined except if the operand is a 4-component vector and the result is a 3-component vector. In this case, the bits in the operand shall be returned directly without modification as the new type. That is, a conforming implementation shall explicitly define a behavior, but two conforming implementations need not have the same behavior when the number of elements in the result and operand types does not match. The implementation may define the result to contain all, some or none of the original bits in whatever order it chooses. It is an error to use the as_type() or as_typen() operators to reinterpret data to a type of a different number of bytes. Notes While the union is intended to reflect the organization of data in memory, the as_type() and as_typen() constructs are intended to reflect the organization of data in register. The as_type() and as_typen() constructs are intended to compile to no instructions on devices that use a shared register file designed to operate on both the operand and result types. Note that while differences in memory organization are expected to largely be limited to those arising from endianness, the register based representation may also differ due to size of the element in register. (For example, an architecture may load a char into a 32-bit register, or a char vector into a SIMD vector register with fixed 32-bit element size.) If the element count does not match, then the implementation should pick a data representation that most closely matches what would happen if an appropriate result type operator was applied to a register containing data of the source type. If the number of elements matches, then the as_typen() should faithfully reproduce the behavior expected from a similar data type reinterpretation using memory/unions. So, for example if an implementation stores all single precision data as double in register, it should implement as_int( float ) by first downconverting the double to single precision and then (if necessary) moving the single precision bits to a register suitable for operating on integer data. If data stored in different address spaces do not have the same endianness, then the "dominant endianness" of the device should prevail. Example float f = 1.0f; uint u = as_uint(f); // Legal. Contains: 0x3f800000 float4 f = (float4)(1.0f, 2.0f, 3.0f, 4.0f); // Legal. Contains: (int4) // (0x3f800000, 0x40000000, 0x40400000, 0x40800000) int4 i = as_int4(f); float4 f, g; int4 is_less = f < g; // Legal. f[i] = f[i] < g[i] ? f[i] : 0.0f f = as_float4(as_int4(f) & is_less); int i; // Legal.

The size of each element in the mask must match the size of each element in the result. For shuffle, only the ilogb(2m-1) least significant bits of each mask element are considered. For shuffle2, only the ilogb(2m-1)+1 least significant bits of each mask element are considered. Other bits in the mask shall be ignored. The elements of the input vectors are numbered from left to right across one or both of the vectors. For this purpose, the number of elements in a vector is given by vec_step(gentypem). The shuffle mask operand specifies, for each element of the result vector, which element of the one or two input vectors the result element gets. We use the generic type name gentypen (or gentypem) to indicate the built-in data types char{2|4|8|16}, uchar{2|4|8|16}, short{2|4|8|16}, ushort{2|4|8|16}, int{2|4|8|16}, uint{2|4|8|16}, long{2|4|8|16}, ulong{2|4|8|16}, or float{2|4|8|16} as the type for the arguments unless otherwise stated. We use the generic name ugentypen to indicate the built-in unsigned integer data types. If the double is supported, then gentypen (or gentypem) also indicate the built-in data types double{2|4|8|16}.

The pointer returned by clEnqueueMapBuffer or clEnqueueMapImage is guaranteed to contain the latest bits in the region being mapped when the clEnqueueMapBuffer or clEnqueueMapImage command has completed CL_MAP_WRITE This flag specifies that the region being mapped in the memory object is being mapped for writing. The pointer returned by clEnqueueMapBuffer or clEnqueueMapImage is guaranteed to contain the latest bits in the region being mapped when the clEnqueueMapBuffer or clEnqueueMapImage command has completed. CL_MAP_WRITE_INVALIDATE_REGION This flag specifies that the region being mapped in the memory object is being mapped for writing. The contents of the region being mapped are to be discarded. This is typically the case when the region being mapped is overwritten by the host. This flag allows the implementation to no longer guarantee that the pointer returned by clEnqueueMapBuffer or clEnqueueMapImage contains the latest bits in the region being mapped which can be a significant performance enhancement. CL_MAP_READ or CL_MAP_WRITE and CL_MAP_WRITE_INVALIDATE_REGION are mutually exclusive. origin Defines the (x, y, z) offset in pixels in the 1D, 2D or 3D image, the (x, y) offset and the image index in the 2D image array or the (x) offset and the image index in the 1D image array. If image is a 2D image object, origin[2] must be 0. If image is a 1D image or 1D image buffer object, origin[1] and origin[2] must be 0. If image is a 1D image array object, origin[2] must be 0. If image is a 1D image array object, origin[1] describes the image index in the 1D image array. If image is a 2D image array object, origin[2] describes the image index in the 2D image array. region Defines the (width, height, depth) in pixels of the 1D, 2D or 3D rectangle, the (width, height) in pixels of the 2D rectangle and the number of images of a 2D image array or the (width) in pixels of the 1D rectangle and the number of images of a 1D image array. If image is a 2D image object, region[2] must be 1. If image is a 1D image or 1D image buffer object, region[1] and region[2] must be 1. If image is a 1D image array object, region[2] must be 1. image_row_pitch Returns the scan-line pitch in bytes for the mapped region. This must be a non-NULL value. image_slice_pitch Returns the size in bytes of each 2D slice of a 3D image or the size of each 1D or 2D image in a 1D or 2D image array for the mapped region. For a 1D and 2D image, zero is returned if this argument is not NULL. For a 3D image, 1D, and 2D image array, image_slice_pitch must be a non-NULL value. event_wait_list , num_events_in_wait_list Specify events that need to complete before clEnqueueMapImage can be executed. If event_wait_list is NULL, then clEnqueueMapImage does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. event Returns an event object that identifies this particular copy command and can be used to query or queue a wait for this particular command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. If the event_wait_list and the event arguments are not NULL, the event argument should not refer to an element of the event_wait_list array. errcode_ret Returns an appropriate error code. If errcode_ret is NULL, no error code is returned. Notes The pointer returned maps a 1D, 2D or 3D region starting at origin and is at least region[0] pixels in size for a 1D image, 1D image buffer or 1D image array, (image_row_pitch * region[1]) pixels in size for a 2D image or 2D image array, and (image_slice_pitch * region[2]) pixels in size for a 3D image. The result of a memory access outside this region is undefined. If the image object is created with CL_MEM_USE_HOST_PTR set in mem_flags, the following will be true: The host_ptr specified in clCreateImage is guaranteed to contain the latest bits in the region being mapped when the clEnqueueMapImage command has completed. The pointer value returned by clEnqueueMapImage will be derived from the host_ptr specified when the image object is created. Mapped image objects are unmapped using clEnqueueUnmapMemObject. clEnqueueMapBuffer and clEnqueueMapImage increment the mapped count of the memory object. The initial mapped count value of a memory object is zero. Multiple calls to clEnqueueMapBuffer or clEnqueueMapImage on the same memory object will increment this mapped count by appropriate number of calls. clEnqueueUnmapMemObject decrements the mapped count of the memory object. clEnqueueMapBuffer and clEnqueueMapImage act as synchronization points for a region of the buffer object being mapped. Errors clEnqueueMapImage will return a pointer to the mapped region if the function is executed successfully. The errcode_ret is set to CL_SUCCESS. A NULL pointer is returned otherwise with one of the following error values returned in errcode_ret: CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_CONTEXT if the context associated with command_queue and image are not the same or if the context associated with command_queue and events in event_wait_list are not the same. CL_INVALID_MEM_OBJECT if image is not a valid image object. CL_INVALID_VALUE if region being mapped given by (origin, origin+region) is out of bounds or if values specified in map_flags are not valid. CL_INVALID_VALUE if values in origin and region do not follow rules described in the argument description for origin and region. CL_INVALID_VALUE if image_row_pitch is NULL. CL_INVALID_VALUE if image is a 3D image, 1D or 2D image array object and image_slice_pitch is NULL. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list > 0, or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects in event_wait_list are not valid events. CL_INVALID_IMAGE_SIZE if image dimensions (image width, height, specified or compute row and/or slice pitch) for image are not supported by device associated with queue. CL_INVALID_IMAGE_FORMAT if image format (image channel order and data type) for image are not supported by device associated with queue. CL_MAP_FAILURE if there is a failure to map the requested region into the host address space. This error cannot occur for image objects created with CL_MEM_USE_HOST_PTR or CL_MEM_ALLOC_HOST_PTR. CL_EXEC_STATUS_ERROR_FOR_EVENTS_IN_WAIT_LIST if the map operation is blocking and the execution status of any of the events in event_wait_list is a negative integer value. CL_MEM_OBJECT_ALLOCATION_FAILURE if there is a failure to allocate memory for data store associated with buffer. CL_INVALID_OPERATION if the device associated with command_queue does not support images (i.e. CL_DEVICE_IMAGE_SUPPORT specified in the table of OpenCL Device Queries for clGetDeviceInfo is CL_FALSE. CL_INVALID_OPERATION if image has been created with CL_MEM_HOST_WRITE_ONLY or CL_MEM_HOST_NO_ACCESS and CL_MAP_READ is set in map_flags or if image has been created with CL_MEM_HOST_READ_ONLY or CL_MEM_HOST_NO_ACCESS and CL_MAP_WRITE or CL_MAP_WRITE_INVALIDATE_REGION is set in map_flags. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

Failure to provide such synchronization may result in race conditions and other undefined behavior including non-portability between implementations. Prior to calling clEnqueueAcquireGLObjects, the application must ensure that any pending GL operations which access the objects specified in mem_objects have completed. This may be accomplished portably by issuing and waiting for completion of a glFinish command on all GL contexts with pending references to these objects. Implementations may offer more efficient synchronization methods; for example on some platforms calling glFlush may be sufficient, or synchronization may be implicit within a thread, or there may be vendor-specific extensions that enable placing a fence in the GL command stream and waiting for completion of that fence in the CL command queue. Note that no synchronization methods other than glFinish are portable between OpenGL implementations at this time. Similarly, after calling clEnqueueReleaseGLObjects, the application is responsible for ensuring that any pending OpenCL operations which access the objects specified in mem_objects have completed prior to executing subsequent GL commands which reference these objects. This may be accomplished portably by calling clWaitForEvents with the event object returned by clEnqueueReleaseGLObjects, or by calling clFinish. As above, some implementations may offer more efficient methods. The application is responsible for maintaining the proper order of operations if the CL and GL contexts are in separate threads. If a GL context is bound to a thread other than the one in which clEnqueueReleaseGLObjects is called, changes to any of the objects in mem_objects may not be visible to that context without additional steps being taken by the application. For an OpenGL 3.1 (or later) context, the requirements are described in Appendix D ("Shared Objects and Multiple Contexts") of the OpenGL 3.1 Specification. For prior versions of OpenGL, the requirements are implementation-dependent. Attempting to access the data store of an OpenGL object after it has been acquired by OpenCL and before it has been released will result in undefined behavior. Similarly, attempting to access a shared CL/GL object from OpenCL before it has been acquired by the OpenCL command queue, or after it has been released, will result in undefined behavior. If the cl_khr_gl_event extension is supported, then the OpenCL implementation will ensure that any such pending OpenGL operations are complete for an OpenGL context bound to the same thread as the OpenCL context. This is referred to as implicit synchronization. khronos-opencl-man-1.0~svn22836/cl_khr_fp16.xml0000644000175000017500000003163011660441607021120 0ustar mathieumathieu cl_khr_fp16 cl_khr_fp16 2007-2011 The Khronos Group Inc.

The list of built-in scalar and vector data types are extended to include the types in the table below. The built-in vector data types for halfn are also declared as appropriate types in the OpenCL API (and header files) that can be used by an application. The following table describes the built-in vector data types for halfn as defined in the OpenCL C programming language and the corresponding data type available to the application: Type in OpenCL Language Description API type for application half2 2-component half-precision floating-point vector cl_half2 half3 3-component half-precision floating-point vector cl_half3 half4 4-component half-precision floating-point vector cl_half4 half8 8-component half-precision floating-point vector cl_half8 half16 16-component half-precision floating-point vector cl_half16 The relational, equality, logical and logical unary operators can be used with half scalar and halfn vector types and shall produce a scalar int and vector shortn result respectively. The OpenCL compiler accepts an h and H suffix on floating point literals, indicating the literal is typed as a half. The macro names given in the following list must use the values specified. These constant expressions are suitable for use in #if preprocessing directives. The following table also describes the corresponding macro names available to the application.

If this extension is supported, "cl_khr_gl_sharing" will be returned for CL_DEVICE_EXTENSIONS using clGetDeviceInfo. The OpenCL specification in section 9.7 defines how to share data with texture and buffer objects in a parallel OpenGL implementation, but does not define how the association between an OpenCL context and an OpenGL context or share group is established. This extension defines optional attributes to OpenCL context creation routines which associate a GL context or share group object with a newly created OpenCL context. If this extension is supported by an implementation, the string cl_khr_gl_sharing will be present in the CL_PLATFORM_EXTENSIONS or CL_DEVICE_EXTENSIONS string described in the table of allowed values for param_name for clGetDeviceInfo An OpenGL implementation supporting buffer objects and sharing of texture and buffer object images with OpenCL is required by this extension. This section discusses OpenCL functions that allow applications to use OpenGL buffer, texture, and renderbuffer objects as OpenCL memory objects. This allows efficient sharing of data between OpenCL and OpenGL. The OpenCL API may be used to execute kernels that read and/or write memory objects that are also OpenGL objects. An OpenCL image object may be created from an OpenGL texture or renderbuffer object. An OpenCL buffer object may be created from an OpenGL buffer object. OpenCL memory objects may be created from OpenGL objects if and only if the OpenCL context has been created from an OpenGL share group object or context. OpenGL share groups and contexts are created using platform specific APIs such as EGL, CGL, WGL, and GLX. On MacOS X, an OpenCL context may be created from an OpenGL share group object using the OpenCL platform extension cl_apple_gl_sharing. On other platforms including Microsoft Windows, Linux/Unix and others, an OpenCL context may be created from an OpenGL context using the Khronos platform extension cl_khr_gl_sharing. Refer to the platform documentation for your OpenCL implementation, or visit the Khronos Registry at http://www.khronos.org/registry/cl/ for more information. Any supported OpenGL object defined within the GL share group object, or the share group associated with the GL context from which the CL context is created, may be shared, with the exception of the default OpenGL objects (i.e. objects named zero), which may not be shared. &gl_formatsInc; &gl_syncInc; &gl_lifetimeInc; OpenCL Functions That Allow Sharing Click an item in the table for details about that function. clGetGLContextInfoKHR Query the device. clCreateFromGLBuffer Creates an OpenCL buffer object from an OpenGL buffer object. clCreateFromGLTexture Creates an OpenCL image object, image array object, or image buffer object from an OpenGL texture object, texture array object, texture buffer object, or a single face of an OpenGL cubemap texture object. clCreateFromGLRenderbuffer Creates an OpenCL 2D image object from an OpenGL renderbuffer object. clGetGLObjectInfo Query an OpenGL memory object used to create an OpenCL memory object. clGetGLTextureInfo Get additional information about the GL texture object associated with a memory object. clEnqueueAcquireGLObjects Acquire OpenCL memory objects that have been created from OpenGL objects. clEnqueueReleaseGLObjects Release OpenCL memory objects that have been created from OpenGL objects.

A buffer memory object can be declared as a pointer to a scalar, vector or user-defined struct. This allows the kernel to read and/or write any location in the buffer. The actual size of the array memory object is determined when the memory object is allocated via appropriate API calls in the host code. If an image object is attached to an argument declared with this qualifier, the argument must be declared as type image2d_t for a 2D image object, as type image3d_t for a 3D image object, as type image2d_array_t for a 2D image array object, as type image1d_t for a 1D image object, as type image1d_buffer_t for a 1D image buffer object, and as type image1d_array_t for a 1D image array object. The elements of an image object cannot be directly accessed. Built-in functions to read from and write to an image object are provided. The const qualifier can also be used with the __global qualifier to specify a read-only buffer memory object. Examples &qualifierExampleInc; __global float4 *color; // An array of float4 elements typedef struct { float a[3]; int b[2]; } foo_t; __global foo_t *my_info; // An array of foo_t elements.

If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event returns an event object that identifies this particular command and can be used to query or queue a wait for this particular command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. If the event_wait_list and the event arguments are not NULL, the event argument should not refer to an element of the event_wait_list array. Notes The Direct3D 10 objects are released by the OpenCL context associated with command_queue. OpenCL memory objects created from Direct3D 10 resources which have been acquired by OpenCL must be released by OpenCL before they may be accessed by Direct3D 10. Accessing a Direct3D 10 resource while its corresponding OpenCL memory object is acquired is in error and will result in undefined behavior, including but not limited to possible OpenCL errors, data corruption, and program termination. If CL_CONTEXT_INTEROP_USER_SYNC is not specified as CL_TRUE during context creation, clEnqueueReleaseD3D10ObjectsKHR provides the synchronization guarantee that any calls to Direct3D 10 calls involving the interop device(s) used in the OpenCL context made after the call to clEnqueueReleaseD3D10ObjectsKHR will not start executing until after all events in event_wait_list are complete and all work already submitted to command_queue completes execution. If the context was created with properties specifying CL_CONTEXT_INTEROP_USER_SYNC as CL_TRUE, the user is responsible for guaranteeing that any Direct3D 10 calls involving the interop device(s) used in the OpenCL context made after clEnqueueReleaseD3D10ObjectsKHR will not start executing until after event returned by clEnqueueReleaseD3D10ObjectsKHR reports completion. &sharingD3D10Inc; Errors Returns CL_SUCCESS returns CL_SUCCESS if the function is executed successfully.

CL_INVALID_MEM_OBJECT if memory objects in mem_objects are not valid OpenCL memory objects or if memory objects in mem_objects have not been created from Direct3D 10 resources. CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_CONTEXT if context associated with command_queue was not created from an Direct3D 10 context.

These implementation allocated samplers will count against the maximum sampler values supported by the device and given by CL_DEVICE_MAX_SAMPLERS. Enqueuing a kernel that requires more samplers than the implementation can support will result in a CL_OUT_OF_RESOURCES error being returned.

If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. If event_wait_list is NULL, then this particular command waits until all previous enqueued commands to command_queue have completed. event Returns an event object that identifies this particular command. Event objects are unique and can be used to identify this marker command later on. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. If the event_wait_list and the event arguments are not NULL, the event argument should not refer to an element of the event_wait_list array. Description Enqueues a marker command which waits for either a list of events to complete, or if the list is empty it waits for all commands previously enqueued in command_queue to complete before it completes. This command returns an event which can be waited on, i.e. this event can be waited on to insure that all events either in the event_wait_list or all previously enqueued commands, queued before this command to command_queue, have completed. Errors Returns CL_SUCCESS if the function executed successfully, or one of the errors below: CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list > 0, or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects in event_wait_list are not valid events.

For the forms that take an image3d_array_t, use coord.xy to do an element lookup in the 2D image identified by coord.z in the 2D image array specified by image. The samplerless read image functions behave exactly as the corresponding read image functions that take integer coordinates and a sampler with filter mode set to CLK_FILTER_NEAREST, normalized coordinates set to CLK_NORMALIZED_COORDS_FALSE and addressing mode to CLK_ADDRESS_NONE. read_imagef returns floating-point values in the range [0.0... 1.0] for image objects created with image_channel_data_type set to one of the predefined packed formats or CL_UNORM_INT8 or CL_UNORM_INT16. read_imagef returns floating-point values in the range [-1.0... 1.0] for image objects created with image_channel_data_type set to CL_SNORM_INT8, or CL_SNORM_INT16. read_imagef returns floating-point values for image objects created with image_channel_data_type set to CL_HALF_FLOAT or CL_FLOAT. The read_imagef calls that take integer coordinates must use a sampler with filter mode set to CLK_FILTER_NEAREST, normalized coordinates set to CLK_NORMALIZED_COORDS_FALSE and addressing mode set to CLK_ADDRESS_CLAMP_TO_EDGE, CLK_ADDRESS_CLAMP or CLK_ADDRESS_NONE; otherwise the values returned are undefined. Values returned by read_imagef for image objects with image_channel_data_type values not specified in the description above are undefined.

If the GL object is deleted through the GL API (e.g. glDeleteBuffers, glDeleteTextures, or glDeleteRenderbuffers), subsequent use of the CL buffer or image object will result in undefined behavior, including but not limited to possible CL errors and data corruption, but may not result in program termination. The CL context and corresponding command-queues are dependent on the existence of the GL share group object, or the share group associated with the GL context from which the CL context is created. If the GL share group object or all GL contexts in the share group are destroyed, any use of the CL context or command-queue(s) will result in undefined behavior, which may include program termination. Applications should destroy the CL command-queue(s) and CL context before destroying the corresponding GL share group or contexts. khronos-opencl-man-1.0~svn22836/ceil.xml0000644000175000017500000000775311660441607017747 0ustar mathieumathieu ]> ceil ceil 2007-2011 The Khronos Group Inc.

If param_value is NULL, it is ignored. param_value_size Specifies the size in bytes of memory pointed to by param_value. This size must be ≥ size of the return type as described in the table below. param_value_size_ret Returns the actual size in bytes of data copied to param_value. If param_value_size_ret is NULL, it is ignored. param_name Specifies the information to query. The list of supported param_name types and the information returned in param_value by clGetEventInfo is described in the table below: cl_event_info Return Type Information returned in param_value CL_EVENT_COMMAND_QUEUE cl_command_queue Return the command-queue associated with event. For user event objects, a NULL value is returned. CL_EVENT_CONTEXT cl_context Return the context associated with event. CL_EVENT_COMMAND_TYPE cl_command_type Return the command associated with event.

The valid values are: CL_QUEUED (command has been enqueued in the command-queue), CL_SUBMITTED (enqueued command has been submitted by the host to the device associated with the command-queue), CL_RUNNING (device is currently executing this command), CL_COMPLETE (the command has completed), or Error code given by a negative integer value. (command was abnormally terminated – this may be caused by a bad memory access etc.) These error codes come from the same set of error codes that are returned from the platform or runtime API calls as return values or errcode_ret values. The error code values are negative, and event state values are positive. The event state values are ordered from the largest value (CL_QUEUED) for the first or initial state to the smallest value (CL_COMPLETE or negative integer value) for the last or complete state. The value of CL_COMPLETE and CL_SUCCESS are the same. CL_EVENT_REFERENCE_COUNT cl_uint Return the event reference count. The reference count returned should be considered immediately stale. It is unsuitable for general use in applications. This feature is provided for identifying memory leaks. Notes Using clGetEventInfo to determine if a command identified by event has finished execution (i.e. CL_EVENT_COMMAND_EXECUTION_STATUS returns CL_COMPLETE) is not a synchronization point. There are no guarantees that the memory objects being modified by command associated with event will be visible to other enqueued commands. Errors Returns CL_SUCCESS if the function executed successfully, or one of the errors below: CL_INVALID_VALUE if param_name is not valid, or if size in bytes specified by param_value_size is < size of return type as described in the table above and param_value is not NULL. CL_INVALID_VALUE if information to query given in param_name cannot be queried for event. CL_INVALID_EVENT if event is not a valid event object. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

Description These are the data types available in the OpenCL C programming language used to create kernels that are executed on OpenCL device(s). The OpenCL C programming language (also referred to as OpenCL C) is based on the ISO/IEC 9899:1999 C language specification (a.k.a. C99 specification) with specific extensions and restrictions. Please refer to the ISO/IEC 9899:1999 specification for a detailed description of the language grammar. This section describes modifications and restrictions to ISO/IEC 9899:1999 supported in OpenCL C. Most built-in scalar data types are also declared as appropriate types in the OpenCL API (and header files) that can be used by an application. The following table describes the built-in scalar data type in the OpenCL C programming language and the corresponding data type available to the application: Type in OpenCL C Language Description API type for application bool A conditional data type which is either true or false. The value true expands to the integer constant 1 and the value false expands to the integer constant 0. When any scalar value is converted to bool, the result is 0 if the value compares equal to 0; otherwise, the result is 1. n/a char A signed two's complement 8-bit integer. cl_char unsigned char, uchar An unsigned 8-bit integer. cl_uchar short A signed two's complement 16-bit integer. cl_short unsigned short, ushort An unsigned 16-bit integer. cl_ushort int A signed two's complement 32-bit integer. cl_int unsigned int, uint An unsigned 32-bit integer. cl_uint long A signed two's complement 64-bit integer. cl_long unsigned long, ulong An unsigned 64-bit integer. cl_ulong float A 32-bit floating point. The float data type must conform to the IEEE 754 single precision storage format. cl_float double A 64-bit floating point. The double data type must conform to the IEEE 754 double precision storage format. The double scalar type is an optional type that is supported if CL_DEVICE_DOUBLE_FP_CONFIG for a device is not zero. See the table for param_name for clGetDeviceInfo for details. cl_double half A 16-bit float. The half data type must conform to the IEEE 754-2008 half precision storage format. cl_half size_t The unsigned integer type of the result of the sizeof operator. This is a 32-bit unsigned integer if CL_DEVICE_ADDRESS_BITS defined in clGetDeviceInfo is 32-bits and is a 64-bit unsigned integer if CL_DEVICE_ADDRESS_BITS is 64-bits. n/a ptrdiff_t A signed integer type that is the result of subtracting two pointers. This is a 32-bit signed integer if CL_DEVICE_ADDRESS_BITS defined in clGetDeviceInfo is 32-bits and is a 64-bit signed integer if CL_DEVICE_ADDRESS_BITS is 64-bits. n/a intptr_t A signed integer type with the property that any valid pointer to void can be converted to this type, then converted back to pointer to void, and the result will compare equal to the original pointer. This is a 32-bit signed integer if CL_DEVICE_ADDRESS_BITS defined in table 4.3 is 32-bits and is a 64-bit signed integer if CL_DEVICE_ADDRESS_BITS is 64-bits. n/a uintptr_t An unsigned integer type with the property that any valid pointer to void can be converted to this type, then converted back to pointer to void, and the result will compare equal to the original pointer. This is a 32-bit signed integer if CL_DEVICE_ADDRESS_BITS defined in table 4.3 is 32-bits and is a 64-bit signed integer if CL_DEVICE_ADDRESS_BITS is 64-bits. n/a void The void type comprises an empty set of values; it is an incomplete type that cannot be completed. void Optional Half Floating Point The half floating-point is supported as an optional extension. An application that wants to use half and halfn will need to include the #pragma OPENCL EXTENSION cl_khr_fp16 : enable directive. This will extended the list of built-in vector and scalar data types to include the following: Type in OpenCL Language Description API type for application half2 A 2-component half-precision floating-point vector. cl_half2 half3 A 3-component half-precision floating-point vector. cl_half3 half4 A 4-component half-precision floating-point vector. cl_half4 half8 An 8-component half-precision floating-point vector. cl_half8 half16 A 16-component half-precision floating-point vector. cl_half16 The relational, equality, logical and logical unary operators can be used with half scalar and halfn vector types and shall produce a scalar int and vector shortn result respectively. The OpenCL compiler accepts an h and H suffix on floating point literals, indicating the literal is typed as a half.

It can either be in the list of devices specified when context is created using clCreateContext or have the same device type as the device type specified when the context is created using clCreateContextFromType. properties Specifies a list of properties for the command-queue. This is a bit-field described in the table below. Only command-queue properties specified in the table below can be set in properties; otherwise the value specified in properties is considered to be not valid. Command-Queue Properties Description CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE Determines whether the commands queued in the command-queue are executed in-order or out-of-order. If set, the commands in the command-queue are executed out-of-order. Otherwise, commands are executed in-order. See note below for more information. CL_QUEUE_PROFILING_ENABLE Enable or disable profiling of commands in the command-queue. If set, the profiling of commands is enabled. Otherwise profiling of commands is disabled. See clGetEventProfilingInfo for more information. errcode_ret Returns an appropriate error code. If errcode_ret is NULL, no error code is returned. Notes OpenCL objects such as memory, program and kernel objects are created using a context. Operations on these objects are performed using a command-queue. The command-queue can be used to queue a set of operations (referred to as commands) in order. Having multiple command-queues allows applications to queue multiple independent commands without requiring synchronization. Note that this should work as long as these objects are not being shared. Sharing of objects across multiple command-queues will require the application to perform appropriate synchronization. This is described in Appendix A of the specification. Out-of-order Execution of Kernels and Memory Object Commands The OpenCL functions that are submitted to a command-queue are enqueued in the order the calls are made but can be configured to execute in-order or out-of-order. The properties argument in clCreateCommandQueue can be used to specify the execution order. If the CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE property of a command-queue is not set, the commands enqueued to a command-queue execute in order. For example, if an application calls clEnqueueNDRangeKernel to execute kernel A followed by a clEnqueueNDRangeKernel to execute kernel B, the application can assume that kernel A finishes first and then kernel B is executed. If the memory objects output by kernel A are inputs to kernel B then kernel B will see the correct data in memory objects produced by execution of kernel A. If the CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE property of a commandqueue is set, then there is no guarantee that kernel A will finish before kernel B starts execution. Applications can configure the commands enqueued to a command-queue to execute out-of-order by setting the CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE property of the command-queue. This can be specified when the command-queue is created. In out-of-order execution mode there is no guarantee that the enqueued commands will finish execution in the order they were queued. As there is no guarantee that kernels will be executed in order, that is based on when the clEnqueueNDRangeKernel calls are made within a command-queue, it is therefore possible that an earlier clEnqueueNDRangeKernel call to execute kernel A identified by event A may execute and/or finish later than a clEnqueueNDRangeKernel call to execute kernel B which was called by the application at a later point in time. To guarantee a specific order of execution of kernels, a wait on a particular event (in this case event A) can be used. The wait for event A can be specified in the event_wait_list argument to clEnqueueNDRangeKernel for kernel B. In addition, a wait for events (clEnqueueMarkerWithWaitList) or a barrier (clEnqueueBarrierWithWaitList) command can be enqueued to the command-queue. The wait for events command ensures that previously enqueued commands identified by the list of events to wait for have finished before the next batch of commands is executed. The barrier command ensures that all previously enqueued commands in a command-queue have finished execution before the next batch of commands is executed. Similarly, commands to read, write, copy or map memory objects that are enqueued after clEnqueueNDRangeKernel, clEnqueueTask or clEnqueueNativeKernel commands are not guaranteed to wait for kernels scheduled for execution to have completed (if the CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE property is set). To ensure correct ordering of commands, the event object returned by clEnqueueNDRangeKernel, clEnqueueTask or clEnqueueNativeKernel can be used to enqueue a wait for event or a barrier command can be enqueued that must complete before reads or writes to the memory object(s) occur. Errors clCreateCommandQueue returns a valid non-zero command-queue and errcode_ret is set to CL_SUCCESS if the command-queue is created successfully. Otherwise, it returns a NULL value with one of the following error values returned in errcode_ret: CL_INVALID_CONTEXT if context is not a valid context. CL_INVALID_DEVICE if device is not a valid device or is not associated with context. CL_INVALID_VALUE if values specified in properties are not valid. CL_INVALID_QUEUE_PROPERTIES if values specified in properties are valid but are not supported by the device. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

The list of supported properties is described in the table below. properties can also be NULL in which case the platform that is selected is implementation-defined. If the cl_khr_gl_sharing extension is supported, properties points to an attribute list whose format and valid contents are identical to the properties argument of clCreateContext which is: properties specifies a list of context property names and their corresponding values. Each property name is immediately followed by the corresponding desired value. The list is terminated with 0. The list of supported properties is described in the table below. properties can be NULL in which case the platform that is selected is implementation-defined. cl_context_properties enum Property value Description CL_CONTEXT_PLATFORM cl_platform_id Specifies the platform to use. CL_CONTEXT_INTEROP_USER_SYNC cl_bool Specifies whether the user is responsible for synchronization between OpenCL and other APIs. Please refer to the specific sections in the OpenCL 1.2 extension specification that describe sharing with other APIs for restrictions on using this flag. If CL_CONTEXT_INTEROP_USER_SYNC is not specified, a default of CL_FALSE is assumed. CL_CONTEXT_D3D10_DEVICE_KHR ID3D10Device * Specifies the ID3D10Device * to use for Direct3D 10 interoperability.

The default value is NULL * (applies if the cl_khr_d3d11_sharing extension is supported) device_type A bit-field that identifies the type of device and is described in the table below. cl_device_type Description CL_DEVICE_TYPE_CPU An OpenCL device that is the host processor. The host processor runs the OpenCL implementations and is a single or multi-core CPU. CL_DEVICE_TYPE_GPU An OpenCL device that is a GPU. By this we mean that the device can also be used to accelerate a 3D API such as OpenGL or DirectX. CL_DEVICE_TYPE_ACCELERATOR Dedicated OpenCL accelerators (for example the IBM CELL Blade). These devices communicate with the host processor using a peripheral interconnect such as PCIe. CL_DEVICE_TYPE_CUSTOM Dedicated accelerators that do not support programs written in OpenCL C. CL_DEVICE_TYPE_DEFAULT The default OpenCL device in the system. The default device cannot be a CL_DEVICE_TYPE_CUSTOM device. CL_DEVICE_TYPE_ALL All OpenCL devices available in the system except CL_DEVICE_TYPE_CUSTOM devices. pfn_notify A callback function that can be registered by the application. This callback function will be used by the OpenCL implementation to report information on errors that occur in this context. This callback function may be called asynchronously by the OpenCL implementation. It is the application's responsibility to ensure that the callback function is thread-safe. If pfn_notify is NULL, no callback function is registered. The parameters to this callback function are: errinfo is a pointer to an error string. private_info and cb represent a pointer to binary data that is returned by the OpenCL implementation that can be used to log additional information helpful in debugging the error. user_data is a pointer to user supplied data. There are a number of cases where error notifications need to be delivered due to an error that occurs outside a context. Such notifications may not be delivered through the pfn_notify callback. Where these notifications go is implementation-defined. user_data Passed as the user_data argument when pfn_notify is called. user_data can be NULL. errcode_ret Return an appropriate error code. If errcode_ret is NULL, no error code is returned. Description Only devices that are returned by clGetDeviceIDs for device_type are used to create the context. The context does not reference any sub-devices that may have been created from these devices. Notes clCreateContextFromType may return all or a subset of the actual physical devices present in the platform and that match device_type. clCreateContextFromType and clCreateContext perform an implicit retain. This is very helpful for 3rd party libraries, which typically get a context passed to them by the application. However, it is possible that the application may delete the context without informing the library. Allowing functions to attach to (i.e. retain) and release a context solves the problem of a context being used by a library no longer being valid. Errors clCreateContextFromType returns a valid non-zero context and errcode_ret is set to CL_SUCCESS if the context is created successfully. Otherwise, it returns a NULL value with the following error vlaues returned in errcode_ret: CL_INVALID_PLATFORM if properties is NULL and no platform could be selected or if platform value specified in properties is not a valid platform. If the cl_khr_gl_sharing extension is supported, this error is replaced (or not) by CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR and possibly CL_INVALID_OPERATION (see below and section 9.6.4 of the spec for clarification). CL_INVALID_PROPERTY if context property name in properties is not a supported property name, or if the value specified for a supported property name is not valid, or if the same property name is specified more than once. CL_INVALID_VALUE if pfn_notify is NULL but user_data is not NULL. CL_INVALID_DEVICE_TYPE if device_type is not a valid value. CL_DEVICE_NOT_AVAILABLE if no devices that match device_type and property values specified in properties are currently available. CL_DEVICE_NOT_FOUND if no devices that match device_type and property values specified in properties were found. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host. CL_INVALID_D3D10_DEVICE_KHR if the Direct3D 10 device specified for interoperability is not compatible with the devices against which the context is to be created (if the cl_khr_d3d10_sharing extension is enabled). CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR when an invalid OpenGL context or share group object handle is specified in properties if the cl_khr_gl_sharing extension is enabled. CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR: If no OpenGL or OpenGL ES context or share group is specified in the attribute list, then memory objects may not be shared, and calling any of the commands in section 9.7 will result in this error (if the cl_khr_gl_sharing extension is enabled). CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR if the cl_khr_gl_sharing extension is enabled and if a context was specified by any of the following means: Context specified for an EGL-based OpenGL ES or OpenGL implementation by setting the attributes CL_GL_CONTEXT_KHR and CL_EGL_DISPLAY_KHR. Context was specified for a GLX-based OpenGL implementation by setting the attributes CL_GL_CONTEXT_KHR and CL_GLX_DISPLAY_KHR. Context was specified for a WGL-based OpenGL implementation by setting the attributes CL_GL_CONTEXT_KHR and CL_WGL_HDC_KHR. and any of the following conditions hold: The specified display and context attributes do not identify a valid OpenGL or OpenGL ES context. The specified context does not support buffer and renderbuffer objects. The specified context is not compatible with the OpenCL context being created (for example, it exists in a physically distinct address space, such as another hardware device, or does not support sharing data with OpenCL due to implementation restrictions). CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR if a share group was specified for a CGL-based OpenGL implementation by setting the attribute CL_CGL_SHAREGROUP_KHR, and the specified share group does not identify a valid CGL share group object (only if the cl_khr_gl_sharing extension is enabled). CL_INVALID_DX9_MEDIA_ADAPTER_KHR if the media adapter specified for interoperability is not compatible with the devices against which the context is to be created (only if the cl_khr_dx9_media_sharing extension is supported). CL_INVALID_ADAPTER_KHR if any of the values of the properties CL_CONTEXT_ADAPTER_D3D9_KHR, CL_CONTEXT_ADAPTER_D3D9EX_KHR or CL_CONTEXT_ADAPTER_DXVA_KHR is non-NULL and does not specify a valid media adapter with which the cl_device_ids against which this context is to be created may interoperate. (only if the cl_khr_dx9_media_sharing extension is supported). CL_INVALID_OPERATION if interoperability is specified by setting CL_CONTEXT_ADAPTER_D3D9_KHR, CL_CONTEXT_ADAPTER_D3D9EX_KHR or CL_CONTEXT_ADAPTER_DXVA_KHR to a non-NULL value, and interoperability with another graphics API is also specified. (only if the cl_khr_dx9_media_sharing extension is supported). CL_INVALID_D3D11_DEVICE_KHR if the Direct3D 11 device specified for interoperability is not compatible with the devices against which the context is to be created (only if the cl_khr_d3d11_sharing extension is supported). CL_INVALID_OPERATION if Direct3D 11 interoperability is specified by setting CL_INVALID_D3D11_DEVICE_KHR to a non-NULL value, and interoperability with another graphics API is also specified. (only if the cl_khr_d3d11_sharing extension is supported). CL_INVALID_D3D11_DEVICE_KHR if the value of the property CL_CONTEXT_D3D11_DEVICE_KHR is non-NULL and does not specify a valid Direct3D 11 device with which the cl_device_ids against which this context is to be created may interoperate. (only if the cl_khr_d3d11_sharing extension is supported).

Only CL_MEM_READ_ONLY, CL_MEM_WRITE_ONLY, and CL_MEM_READ_WRITE values specified in the table at clCreateBuffer can be used. renderbuffer The name of a GL renderbuffer object. The renderbuffer storage must be specified before the image object can be created. The renderbuffer format and dimensions defined by OpenGL will be used to create the 2D image object. Only GL renderbuffers with internal formats that map to appropriate image channel order and data type specified in the table of supported Image Channel Order Values and the table of supported Image Channel Data Types for cl_image_format can be used to create the 2D image object. errcode_ret Returns an appropriate error code as described below. If errcode_ret is NULL, no error code is returned. Description If the state of a GL renderbuffer object is modified through the GL API (i.e. changes to the dimensions or format used to represent pixels of the GL renderbuffer using appropriate GL API calls such as glRenderbufferStorage) while there exists a corresponding CL image object, subsequent use of the CL image object will result in undefined behavior. The clRetainMemObject and clReleaseMemObject functions can be used to retain and release the image objects. &gl_formatsInc; Errors Returns a valid non-zero OpenCL image object and errcode_ret is set to CL_SUCCESS if the image object is created successfully.

The OpenCL context associated with command_queue, src_buffer, and dst_buffer must be the same. src_origin The (x, y, z) offset in the memory region associated with src_buffer. For a 2D rectangle region, the z value given by src_origin[2] should be 0. The offset in bytes is computed as src_origin[2] * src_slice_pitch + src_origin[1] * src_row_pitch + src_origin[0]. dst_origin The (x, y, z) offset in the memory region associated with dst_buffer. For a 2D rectangle region, the z value given by dst_origin[2] should be 0. The offset in bytes is computed as dst_origin[2] * dst_slice_pitch + dst_origin[1] * dst_row_pitch + dst_origin[0]. region The (width, height, depth) in bytes of the 2D or 3D rectangle being copied. For a 2D rectangle, the depth value given by region[2] should be 1. src_row_pitch The length of each row in bytes to be used for the memory region associated with src_buffer. If src_row_pitch is 0, src_row_pitch is computed as region[0]. src_slice_pitch The length of each 2D slice in bytes to be used for the memory region associated with src_buffer. If src_slice_pitch is 0, src_slice_pitch is computed as region[1] * src_row_pitch. dst_row_pitch The length of each row in bytes to be used for the memory region associated with dst_buffer. If dst_row_pitch is 0, dst_row_pitch is computed as region[0]. dst_slice_pitch The length of each 2D slice in bytes to be used for the memory region associated with dst_buffer. If dst_slice_pitch is 0, dst_slice_pitch is computed as region[1] * dst_row_pitch. event_wait_list num_events_in_wait_list Specify events that need to complete before this particular command can be executed. If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. event Returns an event object that identifies this particular copy command and can be used to query or queue a wait for this particular command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. clEnqueueBarrierWithWaitList can be used instead. If the event_wait_list and the event arguments are not NULL, the event argument should not refer to an element of the event_wait_list array. Notes clEnqueueCopyBufferRectenqueues a command to copy a 2D or 3D rectangular region from the buffer object identified by src_buffer to a 2D or 3D region in the buffer object identified by dst_buffer. Copying begins at the source offset and destination offset which are computed as described in the description for src_origin and dst_origin. Each byte of the region's width is copied from the source offset to the destination offset. After copying each width, the source and destination offsets are incremented by their respective source and destination row pitches. After copying each 2D rectangle, the source and destination offsets are incremented by their respective source and destination slice pitches. NOTE: If src_buffer and dst_buffer are the same buffer object, src_row_pitch must equal dst_row_pitch and src_slice_pitch must equal dst_slice_pitch. Errors Returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors: CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_CONTEXT if the context associated with command_queue, src_buffer, and dst_buffer are not the same or if the context associated with command_queue and events in event_wait_list are not the same. CL_INVALID_MEM_OBJECT if src_buffer and dst_buffer are not valid buffer objects. CL_INVALID_VALUE if (src_offset, region) or (dst_offset, region) require accessing elements outside the src_buffer and dst_buffer objects respectively. CL_INVALID_VALUE if any region array element is 0. CL_INVALID_VALUE if src_row_pitch is not 0 and is less than region[0]. CL_INVALID_VALUE if dst_row_pitch is not 0 and is less than region[0]. CL_INVALID_VALUE if src_slice_pitch is not 0 and is less than region[1] * src_row_pitch or if src_slice_pitch is not 0 and is not a multiple of src_row_pitch. CL_INVALID_VALUE if dst_slice_pitch is not 0 and is less than region[1] * dst_row_pitch or if dst_slice_pitch is not 0 and is not a multiple of dst_row_pitch. CL_INVALID_VALUE if src_buffer and dst_buffer are the same buffer object and src_slice_pitch is not equal to dst_slice_pitch and src_row_pitch is not equal to dst_row_pitch. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list is > 0, or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects in event_wait_list are not valid events. CL_MEM_COPY_OVERLAP if src_buffer and dst_buffer are the same buffer object and the source and destination regions overlap or if src_buffer and dst_buffer are different sub-buffers of the same associated buffer object and they overlap. Refer to Appendix E in the OpenCL specification for details on how to determine if source and destination regions overlap. CL_MISALIGNED_SUB_BUFFER_OFFSET if src_buffer is a sub-buffer object and offset specified when the sub-buffer object is created is not aligned to CL_DEVICE_MEM_BASE_ADDR_ALIGN value for device associated with queue. CL_MISALIGNED_SUB_BUFFER_OFFSET if dst_buffer is a sub-buffer object and offset specified when the sub-buffer object is created is not aligned to CL_DEVICE_MEM_BASE_ADDR_ALIGN value for device associated with queue. CL_MEM_OBJECT_ALLOCATION_FAILURE if there is a failure to allocate memory for data store associated with src_buffer or dst_buffer. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

For forms that take an image1d_array_t, Use coord.x to do an element lookup in the 1D image identified by coord.y in the 1D image array specified by image. The samplerless read image functions behave exactly as the corresponding read image functions that take integer coordinates and a sampler with filter mode set to CLK_FILTER_NEAREST, normalized coordinates set to CLK_NORMALIZED_COORDS_FALSE and addressing mode to CLK_ADDRESS_NONE. read_imageh returns half floating-point values in the range [0.0... 1.0] for image objects created with image_channel_data_type set to one of the predefined packed formats or CL_UNORM_INT8 or CL_UNORM_INT16. read_imageh returns half floating-point values in the range [-1.0... 1.0] for image objects created with image_channel_data_type set to CL_SNORM_INT8, or CL_SNORM_INT16. read_imageh returns half floating-point values for image objects created with image_channel_data_type set to CL_HALF_FLOAT. The read_imageh calls that take integer coordinates must use a sampler with filter mode set to CLK_FILTER_NEAREST, normalized coordinates set to CLK_NORMALIZED_COORDS_FALSE and addressing mode set to CLK_ADDRESS_CLAMP_TO_EDGE, CLK_ADDRESS_CLAMP or CLK_ADDRESS_NONE; otherwise the values returned are undefined.

If the event_wait_list and the event arguments are not NULL, the event argument should not refer to an element of the event_wait_list array. Notes Enqueues a barrier command which waits for either a list of events to complete, or if the list is empty it waits for all commands previously enqueued in command_queue to complete before it completes. This command blocks command execution, that is, any following commands enqueued after it do not execute until it completes. This command returns an event which can be waited on, i.e. this event can be waited on to insure that all events either in the event_wait_list or all previously enqueued commands, queued before this command to command_queue, have completed. Errors Returns CL_SUCCESS if the function was successfully executed. Otherwise, it returns one of the following errors: CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list > 0, or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects in event_wait_list are not valid events. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0.

The kernel will be queued for execution on the device associated with command_queue. kernel A valid kernel object. The OpenCL context associated with kernel and command_queue must be the same. work_dim The number of dimensions used to specify the global work-items and work-items in the work-group. work_dim must be greater than zero and less than or equal to CL_DEVICE_MAX_WORK_ITEM_DIMENSIONS. global_work_offset global_work_offset can be used to specify an array of work_dim unsigned values that describe the offset used to calculate the global ID of a work-item. If global_work_offset is NULL, the global IDs start at offset (0, 0, ... 0). global_work_size Points to an array of work_dim unsigned values that describe the number of global work-items in work_dim dimensions that will execute the kernel function. The total number of global work-items is computed as global_work_size[0] *...* global_work_size[work_dim - 1]. local_work_size Points to an array of work_dim unsigned values that describe the number of work-items that make up a work-group (also referred to as the size of the work-group) that will execute the kernel specified by kernel. The total number of work-items in a work-group is computed as local_work_size[0] *... * local_work_size[work_dim - 1]. The total number of work-items in the work-group must be less than or equal to the CL_DEVICE_MAX_WORK_GROUP_SIZE value specified in table of OpenCL Device Queries for clGetDeviceInfo and the number of work-items specified in local_work_size[0],... local_work_size[work_dim - 1] must be less than or equal to the corresponding values specified by CL_DEVICE_MAX_WORK_ITEM_SIZES[0],.... CL_DEVICE_MAX_WORK_ITEM_SIZES[work_dim - 1]. The explicitly specified local_work_size will be used to determine how to break the global work-items specified by global_work_size into appropriate work-group instances. If local_work_size is specified, the values specified in global_work_size[0],... global_work_size[work_dim - 1] must be evenly divisible by the corresponding values specified in local_work_size[0],... local_work_size[work_dim - 1]. local_work_size can also be a NULL value in which case the OpenCL implementation will determine how to be break the global work-items into appropriate work-group instances. event_wait_list and num_events_in_wait_list Specify events that need to complete before this particular command can be executed. If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. event Returns an event object that identifies this particular kernel execution instance. Event objects are unique and can be used to identify a particular kernel execution instance later on. If event is NULL, no event will be created for this kernel execution instance and therefore it will not be possible for the application to query or queue a wait for this particular kernel execution instance. Notes The work-group size to be used for kernel can also be specified in the program source using the __attribute__ ((reqd_work_group_size(X, Y, Z))) qualifier. In this case the size of work group specified by local_work_size must match the value specified by the reqd_work_group_size __attribute__ qualifier. These work-group instances are executed in parallel across multiple compute units or concurrently on the same compute unit. Each work-item is uniquely identified by a global identifier. The global ID, which can be read inside the kernel, is computed using the value given by global_work_size and global_work_offset. In addition, a work-item is also identified within a work-group by a unique local ID. The local ID, which can also be read by the kernel, is computed using the value given by local_work_size. The starting local ID is always (0, 0, ... 0). Errors Returns CL_SUCCESS if the kernel execution was successfully queued. Otherwise, it returns one of the following errors: CL_INVALID_PROGRAM_EXECUTABLE if there is no successfully built program executable available for device associated with command_queue. CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_KERNEL if kernel is not a valid kernel object. CL_INVALID_CONTEXT if context associated with command_queue and kernel is not the same or if the context associated with command_queue and events in event_wait_list are not the same. CL_INVALID_KERNEL_ARGS if the kernel argument values have not been specified. CL_INVALID_WORK_DIMENSION if work_dim is not a valid value (i.e. a value between 1 and 3). CL_INVALID_GLOBAL_WORK_SIZE if global_work_size is NULL, or if any of the values specified in global_work_size[0], ...global_work_size [work_dim - 1] are 0 or exceed the range given by the sizeof(size_t) for the device on which the kernel execution will be enqueued. CL_INVALID_GLOBAL_OFFSET if the value specified in global_work_size + the corresponding values in global_work_offset for any dimensions is greater than the sizeof(size_t) for the device on which the kernel execution will be enqueued. CL_INVALID_WORK_GROUP_SIZE if local_work_size is specified and number of work-items specified by global_work_size is not evenly divisable by size of work-group given by local_work_size or does not match the work-group size specified for kernel using the __attribute__ ((reqd_work_group_size(X, Y, Z))) qualifier in program source. CL_INVALID_WORK_GROUP_SIZE if local_work_size is specified and the total number of work-items in the work-group computed as local_work_size[0] *... local_work_size[work_dim - 1] is greater than the value specified by CL_DEVICE_MAX_WORK_GROUP_SIZE in the table of OpenCL Device Queries for clGetDeviceInfo. CL_INVALID_WORK_GROUP_SIZE if local_work_size is NULL and the __attribute__ ((reqd_work_group_size(X, Y, Z))) qualifier is used to declare the work-group size for kernel in the program source. CL_INVALID_WORK_ITEM_SIZE if the number of work-items specified in any of local_work_size[0], ... local_work_size[work_dim - 1] is greater than the corresponding values specified by CL_DEVICE_MAX_WORK_ITEM_SIZES[0], .... CL_DEVICE_MAX_WORK_ITEM_SIZES[work_dim - 1]. CL_MISALIGNED_SUB_BUFFER_OFFSET if a sub-buffer object is specified as the value for an argument that is a buffer object and the offset specified when the sub-buffer object is created is not aligned to CL_DEVICE_MEM_BASE_ADDR_ALIGN value for device associated with queue. CL_INVALID_IMAGE_SIZE if an image object is specified as an argument value and the image dimensions (image width, height, specified or compute row and/or slice pitch) are not supported by device associated with queue. CL_INVALID_IMAGE_FORMAT if an image object is specified as an argument value and the image format (image channel order and data type) is not supported by device associated with queue. CL_OUT_OF_RESOURCES if there is a failure to queue the execution instance of kernel on the command-queue because of insufficient resources needed to execute the kernel. For example, the explicitly specified local_work_size causes a failure to execute the kernel because of insufficient resources such as registers or local memory. Another example would be the number of read-only image args used in kernel exceed the CL_DEVICE_MAX_READ_IMAGE_ARGS value for device or the number of write-only image args used in kernel exceed the CL_DEVICE_MAX_WRITE_IMAGE_ARGS value for device or the number of samplers used in kernel exceed CL_DEVICE_MAX_SAMPLERS for device. CL_MEM_OBJECT_ALLOCATION_FAILURE if there is a failure to allocate memory for data store associated with image or buffer objects specified as arguments to kernel. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list > 0, or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects in event_wait_list are not valid events.

Each partition name is immediately followed by the corresponding desired value. The list is terminated with 0. The list of supported partitioning schemes is described in the table below. Only one of the listed partitioning schemes can be specified in properties. cl_device_partition_ property enum (Partition value) Description CL_DEVICE_PARTITION_EQUALLY (unsigned int) Split the aggregate device into as many smaller aggregate devices as can be created, each containing n compute units. The value n is passed as the value accompanying this property. If n does not divide evenly into CL_DEVICE_PARTITION_MAX_COMPUTE_UNITS, then the remaining compute units are not used. CL_DEVICE_PARTITION_BY_COUNTS (unsigned int) This property is followed by a CL_DEVICE_PARTITION_BY_COUNTS_LIST_END terminated list of compute unit counts. For each nonzero count m in the list, a sub-device is created with m compute units in it. CL_DEVICE_PARTITION_BY_COUNTS_LIST_END is defined to be 0. The number of non-zero count entries in the list may not exceed CL_DEVICE_PARTITION_MAX_SUB_DEVICES. The total number of compute units specified may not exceed CL_DEVICE_PARTITION_MAX_COMPUTE_UNITS. CL_DEVICE_PARTITION_BY_- AFFINITY_DOMAIN (cl_device_affinity_domain) Split the device into smaller aggregate devices containing one or more compute units that all share part of a cache hierarchy. The value accompanying this property may be drawn from the following list: CL_DEVICE_AFFINITY_DOMAIN_NUMA - Split the device into sub-devices comprised of compute units that share a NUMA node. CL_DEVICE_AFFINITY_DOMAIN_L4_CACHE - Split the device into sub-devices comprised of compute units that share a level 4 data cache. CL_DEVICE_AFFINITY_DOMAIN_L3_CACHE - Split the device into sub-devices comprised of compute units that share a level 3 data cache. CL_DEVICE_AFFINITY_DOMAIN_L2_CACHE - Split the device into sub-devices comprised of compute units that share a level 2 data cache. CL_DEVICE_AFFINITY_DOMAIN_L1_CACHE - Split the device into sub-devices comprised of compute units that share a level 1 data cache. CL_DEVICE_AFFINITY_DOMAIN_NEXT_PARTITIONABLE - Split the device along the next partitionable affinity domain. The implementation shall find the first level along which the device or sub-device may be further subdivided in the order NUMA, L4, L3, L2, L1, and partition the device into sub-devices comprised of compute units that share memory subsystems at this level. The user may determine what happened by calling clGetDeviceInfo (CL_DEVICE_PARTITION_TYPE) on the sub-devices. num_devices Size of memory pointed to by out_devices specified as the number of cl_device_id entries. out_devices The buffer where the OpenCL sub-devices will be returned. If out_devices is NULL, this argument is ignored. If out_devices is not NULL, num_devices must be greater than or equal to the number of sub-devices that device may be partitioned into according to the partitioning scheme specified in properties. num_devices_ret Returns the number of sub-devices that device may be partitioned into according to the partitioning scheme specified in properties. If num_devices_ret is NULL, it is ignored. Notes Creates an array of sub-devices that each reference a non-intersecting set of compute units within in_device, according to a partition scheme given by properties. The output sub-devices may be used in every way that the root (or parent) device can be used, including creating contexts, building programs, further calls to clCreateSubDevices and creating command-queues. When a command-queue is created against a sub-device, the commands enqueued on the queue are executed only on the sub-device. Errors Returns CL_SUCCESS if the partition is created successfully. Otherwise, it returns a null value with the following error values returned in errcode_ret: CL_INVALID_DEVICE if in_device is not valid. CL_INVALID_VALUE if values specified in properties are not valid or if values specified in properties are valid but not supported by the device.

This size must be greater than or equal to the size of the return type described in the table below. param_value A pointer to memory where the result of the query is returned as described in the table below. If param_value is NULL, it is ignored. param_value_size_ret Returns the actual size in bytes of data being queried by param_value. If param_value_size_ret is NULL, it is ignored. param_name Return Type Information returned in param_value CL_CURRENT_DEVICE_FOR_GL_CONTEXT_KHR cl_device_id Return the CL device currently associated with the specified OpenGL context. CL_DEVICES_FOR_GL_CONTEXT_KHR cl_device_id[] List of all CL devices which may be associated with the specified OpenGL context. Description The OpenGL object used to create the OpenCL memory object and information about the object type i.e. whether it is a texture, renderbuffer, or buffer object can be queried using this function. Notes The OpenCL specification in section 9.7 defines how to share data with texture and buffer objects in a parallel OpenGL implementation, but does not define how the association between an OpenCL context and an OpenGL context or share group is established. This extension defines optional attributes to OpenCL context creation routines which associate a GL context or share group object with a newly created OpenCL context. If this extension is supported by an implementation, the string "cl_khr_gl_sharing" will be present in the CL_PLATFORM_EXTENSIONS or CL_DEVICE_EXTENSIONS string described in the table of allowed values for param_name for clGetDeviceInfo. An OpenGL implementation supporting buffer objects and sharing of texture and buffer object images with OpenCL is required by this extension. OpenCL device(s) corresponding to an OpenGL context may be queried. Such a device may not always exist (for example, if an OpenGL context is specified on a GPU not supporting OpenCL command queues, but which does support shared CL/GL objects), and if it does exist, may change over time. When such a device does exist, acquiring and releasing shared CL/GL objects may be faster on a command queue corresponding to this device than on command queues corresponding to other devices available to an OpenCL context. Errors Returns CL_SUCCESS if the function is executed successfully. If no device(s) exist corresponding to param_name, the call will not fail, but the value of param_value_size_ret will be zero. Otherwise returns one of the following: CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR when an invalid OpenGL context or share group object handle is specified in properties. CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR if a context was specified by any of the following means: A context was specified for an EGL-based OpenGL ES or OpenGL implementation by setting the attributes CL_GL_CONTEXT_KHR and CL_EGL_DISPLAY_KHR A context was specified for a GLX-based OpenGL implementation by setting the attributes CL_GL_CONTEXT_KHR and CL_GLX_DISPLAY_KHR A context was specified for a WGL-based OpenGL implementation by setting the attributes CL_GL_CONTEXT_KHR and CL_WGL_HDC_KHR and any of the following conditions hold: The specified display and context attributes do not identify a valid OpenGL or OpenGL ES context. The specified context does not support buffer and renderbuffer objects. The specified context is not compatible with the OpenCL context being created (for example, it exists in a physically distinct address space, such as another hardware device; or it does not support sharing data with OpenCL due to implementation restrictions). CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR if a share group was specified for a CGL-based OpenGL implementation by setting the attribute CL_CGL_SHAREGROUP_KHR, and the specified share group does not identify a valid CGL share group object. CL_INVALID_OPERATION if a context was specified as described above and any of the following conditions hold: A context or share group object was specified for one of CGL, EGL, GLX, or WGL and the OpenGL implementation does not support that window-system binding API. More than one of the attributes CL_CGL_SHAREGROUP_KHR, CL_EGL_DISPLAY_KHR, CL_GLX_DISPLAY_KHR, and CL_WGL_HDC_KHR is set to a non-default value. Both of the attributes CL_CGL_SHAREGROUP_KHR and CL_GL_CONTEXT_KHR are set to non-default values. Any of the devices specified in the devices argument cannot support OpenCL objects which share the data store of an OpenGL object. CL_INVALID_VALUE if an attribute name other than those specified in the table of supported properties for clCreateContext is specified in properties. CL_INVALID_VALUE if param_name is not CL_CURRENT_DEVICE_FOR_GL_CONTEXT_KHR or CL_DEVICES_FOR_GL_CONTEXT_KHR; or if the size in bytes specified by param_value_size is less than the size of the return type shown above for CL_CURRENT_DEVICE_FOR_GL_CONTEXT_KHR or CL_DEVICES_FOR_GL_CONTEXT_KHR; and param_value is not a NULL value. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

Notes Waits on the host thread for commands identified by event objects in event_list to complete. A command is considered complete if its execution status is CL_COMPLETE or a negative value. The events specified in event_list act as synchronization points. If the cl_khr_gl_event extension is enabled, event objects can also be used to reflect the status of an OpenGL sync object. The sync object in turn refers to a fence command executing in an OpenGL command stream. This provides another method of coordinating sharing of buffers and images between OpenGL and OpenCL. Errors Returns CL_SUCCESS if the execution status of all events in event_list is CL_COMPLETE. Otherwise, it returns one of the following errors: CL_INVALID_VALUE if num_events is zero or event_list is NULL.. CL_INVALID_CONTEXT if events specified in event_list do not belong to the same context. CL_INVALID_EVENT if event objects specified in event_list are not valid event objects. CL_EXEC_STATUS_ERROR_FOR_EVENTS_IN_WAIT_LIST if the execution status of any of the events in event_list is a negative integer value.

Copy a 1D image object to a scanline of a 2D image object and vice-versa. Copy a 1D image object to a scanline of a 2D slice of a 3D image object and vice-versa. Copy a 1D image object to a scanline of a specific image index of a 1D or 2D image array object and vice-versa. Copy a 2D image object to a 2D image object. Copy a 2D image object to a 2D slice of a 3D image object and vice-versa. Copy a 2D image object to a specific image index of a 2D image array object and vice versa. Copy images from a 1D image array object to a 1D image array object. Copy images from a 2D image array object to a 2D image array object. Copy a 3D image object to a 3D image object. src_origin Defines the (x, y, z) offset in pixels in the 1D, 2D or 3D image, the (x, y) offset and the image index in the 2D image array or the (x) offset and the image index in the 1D image array. If image is a 2D image object, src_origin[2] must be 0. If src_image is a 1D image object, src_origin[1] and src_origin[2] must be 0. If src_image is a 1D image array object, src_origin[2] must be 0. If src_image is a 1D image array object, src_origin[1] describes the image index in the 1D image array. If src_image is a 2D image array object, src_origin[2] describes the image index in the 2D image array. dst_origin Defines the (x, y, z) offset in pixels in the 1D, 2D or 3D image, the (x, y) offset and the image index in the 2D image array or the (x) offset and the image index in the 1D image array. If dst_image is a 2D image object, dst_origin[2] must be 0. If dst_image is a 1D image or 1D image buffer object, dst_origin[1] and dst_origin[2] must be 0. If dst_image is a 1D image array object, dst_origin[2] must be 0. If dst_image is a 1D image array object, dst_origin[1] describes the image index in the 1D image array.

If src_image or dst_image is a 1D image array object, region[2] must be 1. event_wait_list , num_events_in_wait_list Specify events that need to complete before this particular command can be executed. If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. event Returns an event object that identifies this particular copy command and can be used to query or queue a wait for this particular command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. clEnqueueBarrierWithWaitList can be used instead. If the event_wait_list and the event arguments are not NULL, the event argument should not refer to an element of the event_wait_list array. Notes It is currently a requirement that the src_image and dst_image image memory objects for clEnqueueCopyImage must have the exact same image format (i.e. the cl_image_format descriptor specified when src_image and dst_image are created must match).

This extension allows creating OpenCL event objects linked to OpenGL fence sync objects, potentially improving efficiency of sharing images and buffers between the two APIs. The companion GL_ARB_cl_event OpenGL extension provides the complementary functionality of creating an OpenGL sync object from an OpenCL event object. In addition, this extension modifies the behavior of clEnqueueAcquireGLObjects and clEnqueueReleaseGLObjects to implicitly guarantee synchronization with an OpenGL context bound in the same thread as the OpenCL context. If this extension is supported by an implementation, the string cl_khr_gl_event will be present in the CL_PLATFORM_EXTENSIONS or CL_DEVICE_EXTENSIONS string described in the table of param_name values for clGetDeviceInfo. Notes Event objects can also be used to reflect the status of an OpenGL sync object. The sync object in turn refers to a fence command executing in an OpenGL command stream. This provides another method of coordinating sharing of buffers and images between OpenGL and OpenCL (see section 9.7.6.1). If the cl_khr_gl_event extension is supported, then the OpenCL implementation will ensure that any such pending OpenGL operations are complete for an OpenGL context bound to the same thread as the OpenCL context. This is referred to as implicit synchronization. If the cl_khr_gl_event extension is supported and the OpenGL context in question supports fence sync objects, completion of OpenGL commands may also be determined by placing a GL fence command after those commands using glFenceSync, creating an event from the resulting GL sync object using clCreateEventFromGLsyncKHR, and determining completion of that event object via clEnqueueAcquireGLObjects. This method may be considerably more efficient than calling glFinish, and is referred to as explicit synchronization. Explicit synchronization is most useful when an OpenGL context bound to another thread is accessing the memory objects. If the cl_khr_gl_event extension is not supported, completion of OpenGL commands may be determined by issuing and waiting for completion of a glFinish command on all OpenGL contexts with pending references to these objects. Some implementations may offer other efficient synchronization methods. If such methods exist they will be described in platform-specific documentation. Note that no synchronization method other than glFinish is portable between all OpenGL implementations and all OpenCL implementations. While this is the only way to ensure completion that is portable to all platforms, glFinish is an expensive operation and its use should be avoided if the cl_khr_gl_event extension is supported on a platform.

These readonly variables can be accessed by all (global) work-items of the kernel during its execution. Pointers to the __constant address space are allowed as arguments to functions (including kernel functions) and for variables declared inside functions. All string literal storage shall be in the __constant address space. NOTE: Each argument to a kernel that is a pointer to the __constant address space is counted separately towards the maximum number of such arguments, defined as CL_DEVICE_MAX_CONSTANT_ARGS are described in the table for clGetDeviceInfo. Variables in the program scope or the outermost scope of kernel functions can be declared in the __constant address space. These variables are required to be initialized and the values used to initialize these variables must be a compile time constant. Writing to such a variable results in a compile-time error. Implementations are not required to aggregate these declarations into the fewest number of constant arguments. This behavior is implementation defined. Thus portable code must conservatively assume that each variable declared inside a function or in program scope allocated in the __constant address space counts as a separate constant argument.

Description The floatn (or doublen if optional double is supported) value igiven by data is converted to a halfn value using the appropriate rounding mode. For n = 1, 2, 4, 8 and 16, the halfn value is written to the address computed as (p + (offset * n)). The address computed as (p + (offset * n)) must be aligned to sizeof (halfn) bytes. For n = 3, the half3 value is written to the address computed as (p + (offset * 4)). The address computed as (p + (offset * 4)) must be aligned to sizeof (half) * 4 bytes. vstorea_halfn uses the default rounding mode. The default rounding mode is round to the nearest even. An application that wants to use half and halfn types will need to include the #pragma OPENCL EXTENSION cl_khr_fp16 : enable directive.

The following table describes the mapping of the number of channels of an image element to the appropriate components in the float4, int4 or uint4 vector data type for the color values returned by read_image{f|i|ui} or supplied to write_image{f|i|ui}. The unmapped components will be set to 0.0 for red, green and blue channels and will be set to 1.0 for the alpha channel.

If the same sampler is used with multiple images called via read_image{f|i|ui}, then it is possible that an implementation may need to allocate an additional sampler to handle the different border color values that may be needed depending on the image formats being used. These implementation allocated samplers will count against the maximum sampler values supported by the device and given by CL_DEVICE_MAX_SAMPLERS. Enqueuing a kernel that requires more samplers than the implementation can support will result in a CL_OUT_OF_RESOURCES error being returned.

A # pragma directive where the preprocessing token OPENCL (used instead of STDC) does not immediately follow pragma in the directive (prior to any macro replacement) causes the implementation to behave in an implementation-defined manner. The behavior might cause translation to fail or cause the translator or the resulting program to behave in a non-conforming manner. Any such pragma that is not recognized by the implementation is ignored. If the preprocessing token OPENCL does immediately follow pragma in the directive (prior to any macro replacement), then no macro replacement is performed on the directive, and the directive shall have one of the following forms whose meanings are described elsewhere: #pragma OPENCL FP_CONTRACT on-off-switch on-off-switch: one of ON OFF DEFAULT #pragma OPENCL EXTENSION extensionname : behavior #pragma OPENCL EXTENSION all : behavior The following predefined macro names are available. __FILE__ The presumed name of the current source file (a character string literal). __LINE__ The presumed line number (within the current source file) of the current source line (an integer constant). __OPENCL_VERSION__ substitutes an integer reflecting the version number of the OpenCL supported by the OpenCL device. The version of OpenCL described in this document will have __OPENCL_VERSION__ substitute the integer 120. CL_VERSION_1_0 substitutes the integer 100 reflecting the OpenCL 1.0 version. CL_VERSION_1_1 substitutes the integer 110 reflecting the OpenCL 1.1 version. CL_VERSION_1_2 substitutes the integer 120 reflecting the OpenCL 1.2 version. __OPENCL_C_VERSION__ substitutes an integer reflecting the OpenCL C version specified by the -cl-std build option to clBuildProgram or clCompileProgram. If the -cl-std build option is not specified, the OpenCL C version supported by the compiler for this OpenCL device will be used. The version of OpenCL C described in this document will have __OPENCL_C_VERSION__ substitute the integer 120. __ENDIAN_LITTLE__ is used to determine if the OpenCL device is a little endian architecture or a big endian architecture (an integer constant of 1 if device is little endian and is undefined otherwise). Also refer to CL_DEVICE_ENDIAN_LITTLE specified in the table of OpenCL Device Queries for clGetDeviceInfo. __kernel_exec(X, typen) (and kernel_exec(X, typen)) is defined as follows: __kernel __attribute__((work_group_size_hint(X, 1, 1))) \ __attribute__((vec_type_hint(typen))) __IMAGE_SUPPORT__ is used to determine if the OpenCL device supports images. This is an integer constant of 1 if images are supported and is undefined otherwise. Also refer to CL_DEVICE_IMAGE_SUPPORT specified in the table of OpenCL Device Queries for clGetDeviceInfo. __FAST_RELAXED_MATH__ is used to determine if the cl-fast-relaxed-math optimization option is specified in build options given to clBuildProgram or clCompileProgram. This is an integer constant of 1 if the cl-fast-relaxed-math build option is specified and is undefined otherwise. The macro names defined by the C99 specification but not currently supported by OpenCL are reserved for future use. __EMBEDDED_PROFILE__ will be the integer constant 1 for OpenCL devices that implement the embedded profile and is undefined otherwise. CL_PLATFORM_PROFILE defined in table 4.1 (see clGetPlatformInfo) will return the string EMBEDDED_PROFILE if the OpenCL implementation supports the embedded profile only.

The sampler can be passed as an argument to the kernel using clSetKernelArg, or can be declared in the outermost scope of kernel functions, or it can be a constant variable of type sampler_t declared in the program source. Sampler variables in a program are declared to be of type sampler_t. A variable of sampler_t type declared in the program source must be initialized with a 32-bit unsigned integer constant, which is interpreted as a bit-field specifiying the following properties: Addressing Mode Filter Mode Normalized Coordinates These properties control how elements of an image object are read by read_image{f|i|ui}. Samplers can also be declared as global constants in the program source using the syntax shown at the top of this page. The sampler fields are described in the table below: Sampler State Description <normalized coords> Specifies whether the x, y and z coordinates are passed in as normalized or unnormalized values. This must be a literal value and can be one of the following predefined enums: CLK_NORMALIZED_COORDS_TRUE or CLK_NORMALIZED_COORDS_FALSE. The samplers used with an image in multiple calls to read_image{f|i|ui} declared in a kernel must use the same value for <normalized coords>. <addressing mode> Specifies the image addressing-mode i.e. how out-of-range image coordinates are handled. This must be a literal value and can be one of the following predefined enums: CLK_ADDRESS_MIRRORED_REPEAT - Flip the image coordinate at every integer junction. This addressing mode can only be used with normalized coordinates. If normalized coordinates are not used, this addressing mode may generate image coordinates that are undefined. CLK_ADDRESS_REPEAT - out-of-range image coordinates are wrapped to the valid range. This address mode can only be used with normalized coordinates. If normalized coordinates are not used, this addressing mode may generate image coordinates that are undefined. CLK_ADDRESS_CLAMP_TO_EDGE - out-of-range image coordinates are clamped to the extent. CLK_ADDRESS_CLAMP - out-of-range image coordinates will return a border color. This is similar to the GL_ADDRESS_CLAMP_TO_BORDER addressing mode. CLK_ADDRESS_NONE - for this addressing mode the programmer guarantees that the image coordinates used to sample elements of the image refer to a location inside the image; otherwise the results are undefined. For 1D and 2D image arrays, the addressing mode applies only to the x and (x, y) coordinates. The addressing mode for the coordinate which specifies the array index is always CLK_ADDRESS_CLAMP_TO_EDGE <filter mode> Specifies the filtering mode to use. This must be a literal value and can be one of the following predefined enums: CLK_FILTER_NEAREST or CLK_FILTER_LINEAR. Refer to section 8.2 for a description of these filter modes. Notes Note that samplers declared using the constant qualifier are not counted towards the maximum number of arguments pointing to the constant address space or the maximum size of the constant address space allowed per device (i.e. CL_DEVICE_MAX_CONSTANT_ARGS and CL_DEVICE_MAX_CONSTANT_BUFFER_SIZE as described in table 4.3). The maximum number of samplers that can be declared in a kernel can be queried using the CL_DEVICE_MAX_SAMPLERS token in clGetDeviceInfo. If <addressing mode> in sampler is CLK_ADDRESS_CLAMP, then out-of-range image coordinates return the border color. The border color selected depends on the image channel order and can be one of the following values: If the image channel order is CL_A, CL_INTENSITY, CL_Rx, CL_RA, CL_RGx, CL_RGBx, CL_ARGB, CL_BGRA, or CL_RGBA, the border color is (0.0f, 0.0f,0.0f, 0.0f). If the image channel order is CL_R, CL_RG, CL_RGB, or CL_LUMINANCE, the border color is (0.0f, 0.0f, 0.0f, 1.0f) A kernel that uses a sampler with the CL_ADDRESS_CLAMP addressing mode with multiple images may result in additional samplers being used internally by an implementation. If the same sampler is used with multiple images called via read_image{f|i|ui}, then it is possible that an implementation may need to allocate an additional sampler to handle the different border color values that may be needed depending on the image formats being used. These implementation allocated samplers will count against the maximum sampler values supported by the device and given by CL_DEVICE_MAX_SAMPLERS. Enqueuing a kernel that requires more samplers than the implementation can support will result in a CL_OUT_OF_RESOURCES error being returned. Example const sampler_t samplerA = CLK_NORMALIZED_COORDS_TRUE | CLK_ADDRESS_REPEAT | CLK_FILTER_NEAREST; samplerA specifies a sampler that uses normalized coordinates, the repeat addressing mode and a nearest filter.

This function must be encountered by all work-items in a work-group executing the kernel. If barrier is inside a conditional statement, then all work-items must enter the conditional if any work-item enters the conditional statement and executes the barrier. If barrier is inside a loop, all work-items must execute the barrier for each iteration of the loop before any are allowed to continue execution beyond the barrier. The barrier function also queues a memory fence (reads and writes) to ensure correct ordering of memory operations to local or global memory. The flags argument specifies the memory address space and can be set to a combination of the following literal values. CLK_LOCAL_MEM_FENCE - The barrier function will either flush any variables stored in local memory or queue a memory fence to ensure correct ordering of memory operations to local memory. CLK_GLOBAL_MEM_FENCE - The barrier function will queue a memory fence to ensure correct ordering of memory operations to global memory. This can be useful when work-items, for example, write to buffer or image objects and then want to read the updated data.

If device is not a custom device or kernel is not a built-in kernel, clGetKernelArgInfo returns the error CL_INVALID_VALUE. CL_KERNEL_WORK_GROUP_SIZE size_t This provides a mechanism for the application to query the maximum work-group size that can be used to execute a kernel on a specific device given by device.

CL_KERNEL_COMPILE_- WORK_GROUP_SIZE size_t[3] Returns the work-group size specified by the __attribute__((reqd_work_group_size(X, Y, Z))) qualifier. See Function Qualifiers. If the work-group size is not specified using the above attribute qualifier (0, 0, 0) is returned. CL_KERNEL_LOCAL_MEM_SIZE cl_ulong Returns the amount of local memory in bytes being used by a kernel. This includes local memory that may be needed by an implementation to execute the kernel, variables declared inside the kernel with the __local address qualifier and local memory to be allocated for arguments to the kernel declared as pointers with the __local address qualifier and whose size is specified with clSetKernelArg. If the local memory size, for any pointer argument to the kernel declared with the __local address qualifier, is not specified, its size is assumed to be 0. CL_KERNEL_PREFERRED_WORK_- GROUP_SIZE_MULTIPLE size_t Returns the preferred multiple of workgroup size for launch. This is a performance hint. Specifying a workgroup size that is not a multiple of the value returned by this query as the value of the local work size argument to clEnqueueNDRangeKernelwill not fail to enqueue the kernel for execution unless the work-group size specified is larger than the device maximum. CL_KERNEL_PRIVATE_MEM_SIZE cl_ulong Returns the minimum amount of private memory, in bytes, used by each workitem in the kernel. This value may include any private memory needed by an implementation to execute the kernel, including that used by the language built-ins and variable declared inside the kernel with the __private qualifier. param_value_size_ret Returns the actual size in bytes of data copied to param_value. If param_value_size_ret is NULL, it is ignored. Errors Returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors: CL_INVALID_DEVICE if device is not in the list of devices associated with kernel or if device is NULL but there is more than one device associated with kernel. CL_INVALID_VALUE if param_name is not valid, or if size in bytes specified by param_value_size is < size of return type as described in the table above and param_value is not NULL. CL_INVALID_VALUE if param_name is CL_KERNEL_GLOBAL_WORK_SIZE and device is not a custom device or kernel is not a built-in kernel. CL_INVALID_KERNEL if kernel is a not a valid kernel object. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

This callback function may be called asynchronously by the OpenCL implementation. It is the application's responsibility to ensure that the callback function is thread-safe. The parameters to this callback function are: memobj: the memory object being deleted. When the user callback is called by the implementation, this memory object is no longer valid. memobj is only provided for reference purposes. user_data: a pointer to user supplied data. user_data Data which will be passed as the user_data argument when pfn_notify is called. user_data can be NULL. Notes Each call to clSetMemObjectDestructorCallback registers the specified user callback function on a callback stack associated with memobj. The registered user callback functions are called in the reverse order in which they were registered. The user callback functions are called and then the memory object's resources are freed and the memory object is deleted. This provides a mechanism for the application (and libraries) using memobj to be notified when the memory referenced by host_ptr, specified when the memory object is created and used as the storage bits for the memory object, can be reused or freed. When the user callback function is called by the implementation, the contents of the memory region pointed to by host_ptr (if the memory object is created with CL_MEM_USE_HOST_PTR) are undefined. The callback function is typically used by the application to either free or reuse the memory region pointed to by host_ptr. The behavior of calling expensive system routines, OpenCL API calls to create contexts or command-queues, or blocking OpenCL operations from the following list below, in a callback is undefined. clFinish clWaitForEvents blocking calls to clEnqueueReadBuffer, clEnqueueReadBufferRect, clEnqueueWriteBuffer, clEnqueueWriteBufferRect blocking calls to clEnqueueReadImage and clEnqueueWriteImage blocking calls to clEnqueueMapBuffer and clEnqueueMapImage blocking calls to clBuildProgram, clCompileProgram, or clLinkProgram If an application needs to wait for completion of a routine from the above list in a callback, please use the non-blocking form of the function, and assign a completion callback to it to do the remainder of your work. Note that when a callback (or other code) enqueues commands to a command-queue, the commands are not required to begin execution until the queue is flushed. In standard usage, blocking enqueue calls serve this role by implicitly flushing the queue. Since blocking calls are not permitted in callbacks, those callbacks that enqueue commands on a command queue should either call clFlush on the queue before returning or arrange for clFlush to be called later on another thread. The user callback function may not call OpenCL APIs with the memory object for which the callback function is invoked and for such cases the behavior of OpenCL APIs is considered to be undefined. Errors Returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors: CL_INVALID_MEM_OBJECT if memobj is not a valid memory object. CL_INVALID_VALUE if pfn_notify is NULL. CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device. CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.

Description An event object may be created by linking to an OpenGL sync object. Completion of such an event object is equivalent to waiting for completion of the fence command associated with the linked GL sync object. Notes The parameters of an event object linked to a GL sync object will return the following values when queried with clGetEventInfo: The CL_EVENT_COMMAND_QUEUE of a linked event is NULL, because the event is not associated with any OpenCL command queue. The CL_EVENT_COMMAND_TYPE of a linked event is CL_COMMAND_GL_FENCE_SYNC_OBJECT_KHR, indicating that the event is associated with a GL sync object, rather than an OpenCL command. The CL_EVENT_COMMAND_EXECUTION_STATUS of a linked event is either CL_SUBMITTED, indicating that the fence command associated with the sync object has not yet completed, or CL_COMPLETE, indicating that the fence command has completed. clCreateEventFromGLsyncKHR performs an implicit clRetainEvent on the returned event object. Creating a linked event object also places a reference on the linked GL sync object. When the event object is deleted, the reference will be removed from the GL sync object. Events returned from clCreateEventFromGLsyncKHR may only be consumed by clEnqueueAcquireGLObjects. Passing such events to any other CL API will generate a CL_INVALID_EVENT error. Errors Returns a valid OpenCL event object and errcode_ret is set to CL_SUCCESS if the event object is created successfully. Otherwise, it returns a NULL value with one of the following error values returned in errcode_ret: CL_INVALID_CONTEXT if context is not a valid context or was not created from a GL context. CL_INVALID_GL_OBJECT if sync is not the name of a sync object in the GL share group associated with context.

Perform an async gather of num_gentypes gentype elements from src to dst. The src_stride is the stride in elements for each gentype element read from src. The dst_stride is the stride in elements for each gentype element written to dst. The async gather is performed by all work-items in a work-group. This built-in function must therefore be encountered by all work-items in a work-group executing the kernel with the same argument values; otherwise the results are undefined. Returns an event object that can be used by wait_group_events to wait for the async copy to finish. The event argument can also be used to associate the async_work_group_strided_copy with a previous async copy allowing an event to be shared by multiple async copies; otherwise event should be zero. If event argument is non-zero, the event object supplied in event argument will be returned. This function does not perform any implicit synchronization of source data such as using a barrier before performing the copy. The behavior of async_work_group_strided_copy is undefined if src_stride or dst_stride is 0, or if the src_stride or dst_stride values cause the src or dst pointers to exceed the upper bounds of the address space during the copy. Notes The generic type name gentype indicates the built-in data types char, char{2|3|4|8|16}, uchar, uchar{2|3|4|8|16}, short, short{2|3|4|8|16}, ushort, ushort{2|3|4|8|16}, int, int{2|3|4|8|16}, uint, uint{2|3|4|8|16}, long, long{2|3|4|8|16}, ulong, ulong{2|3|4|8|16} or float, float{2|3|4|8|16} as the type for the arguments unless otherwise stated.

If blocking_write is CL_TRUE, the OpenCL implementation copies the data referred to by ptr and enqueues the write operation in the command-queue. The memory pointed to by ptr can be reused by the application after the clEnqueueWriteBufferRect call returns. If blocking_write is CL_FALSE, the OpenCL implementation will use ptr to perform a nonblocking write. As the write is non-blocking the implementation can return immediately. The memory pointed to by ptr cannot be reused by the application after the call returns. The event argument returns an event object which can be used to query the execution status of the write command. When the write command has completed, the memory pointed to by ptr can then be reused by the application. buffer_origin The (x, y, z) offset in the memory region associated with buffer. For a 2D rectangle region, the z value given by buffer_origin[2] should be 0. The offset in bytes is computed as buffer_origin[2] * buffer_slice_pitch + buffer_origin[1] * buffer_row_pitch + buffer_origin[0]. host_origin The (x, y, z) offset in the memory region pointed to by ptr. For a 2D rectangle region, the z value given by host_origin[2] should be 0. The offset in bytes is computed as host_origin[2] * host_slice_pitch + host_origin[1] * host_row_pitch + host_origin[0]. region The (width, height, depth) in bytes of the 2D or 3D rectangle being read or written. For a 2D rectangle copy, the depth value given by region[2] should be 1. buffer_row_pitch The length of each row in bytes to be used for the memory region associated with buffer. If buffer_row_pitch is 0, buffer_row_pitch is computed as region[0]. buffer_slice_pitch The length of each 2D slice in bytes to be used for the memory region associated with buffer. If buffer_slice_pitch is 0, buffer_slice_pitch is computed as region[1] * buffer_row_pitch. host_row_pitch The length of each row in bytes to be used for the memory region pointed to by ptr. If host_row_pitch is 0, host_row_pitch is computed as region[0]. host_slice_pitch The length of each 2D slice in bytes to be used for the memory region pointed to by ptr. If host_slice_pitch is 0, host_slice_pitch is computed as region[1] * host_row_pitch. ptr The pointer to buffer in host memory where data is to be written from. event_wait_list num_events_in_wait_list event_wait_list and num_events_in_wait_list specify events that need to complete before this particular command can be executed. If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. event Returns an event object that identifies this particular write command and can be used to query or queue a wait for this particular command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. Notes Calling clEnqueueWriteBufferRect to update the latest bits in a region of the buffer object with the ptr argument value set to host_ptr and host_origin, buffer_origin values are the same, where host_ptr is a pointer to the memory region specified when the buffer object being written is created with CL_MEM_USE_HOST_PTR, must meet the following requirements in order to avoid undefined behavior: The host memory region given by (buffer_origin region) contains the latest bits when the enqueued write command begins execution. The buffer object or memory objects created from this buffer object are not mapped. The buffer object or memory objects created from this buffer object are not used by any command-queue until the write command has finished execution. Errors clEnqueueWriteBufferRect returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors: CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_CONTEXT if the context associated with command_queue and buffer are not the same or if the context associated with command_queue and events in event_wait_list are not the same. CL_INVALID_MEM_OBJECT if buffer is not a valid buffer object. CL_INVALID_VALUE if the region being read specified by (buffer_origin, region, buffer_row_pitch, buffer_slice_pitch) is out of bounds. CL_INVALID_VALUE if ptr is a NULL value. CL_INVALID_VALUE if any region array element is 0. CL_INVALID_VALUE if buffer_row_pitch is not 0 and is less than region[0].

CL_INVALID_VALUE if buffer_slice_pitch is not 0 and is less than region[1] * buffer_row_pitch and not a multiple of buffer_row_pitch. CL_INVALID_VALUE if host_slice_pitch is not 0 and is less than region[1] * host_row_pitch and not a multiple of host_row_pitch. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list > 0, or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects in event_wait_list are not valid events. CL_MISALIGNED_SUB_BUFFER_OFFSET if buffer is a sub-buffer object and offset specified when the sub-buffer object is created is not aligned to CL_DEVICE_MEM_BASE_ADDR_ALIGN value for device associated with queue. CL_EXEC_STATUS_ERROR_FOR_EVENTS_IN_WAIT_LIST if the read and write operations are blocking and the execution status of any of the events in event_wait_list is a negative integer value.

This is designed to function analogously to the OpenGL interoperability as defined in sections 9.7 and 9.8. If this extension is supported by an implementation, the string "cl_khr_d3d11_sharing" will be present in the CL_PLATFORM_EXTENSIONS or CL_DEVICE_EXTENSIONS string described in the table of allowed values for param_name for clGetDeviceInfo. The interfaces for this extension are provided in the header file cl_d3d11.h. If the cl_khr_d3d11_sharing extension is supported, then the following functions are enabled: clGetDeviceIDsFromD3D11KHR clCreateFromD3D11BufferKHR clCreateFromD3D11Texture2DKHR clCreateFromD3D11Texture3DKHR clEnqueueAcquireD3D11ObjectsKHR clEnqueueReleaseD3D11ObjectsKHR The OpenCL functions enabled by the cl_khr_d3d11_sharing extension allow applications to use Direct3D 11 resources as OpenCL memory objects. This allows efficient sharing of data between OpenCL and Direct3D 11. The OpenCL API may be used to execute kernels that read and/or write memory objects that are also Direct3D 11 resources. An OpenCL image object may be created from a Direct3D 11 texture resource. An OpenCL buffer object may be created from a Direct3D 11 buffer resource.

This allows efficient sharing of data between OpenCL and selected adapter APIs (only DX9 for now). If this extension is supported, an OpenCL image object can be created from a media surface and the OpenCL API can be used to execute kernels that read and/or write memory objects that are media surfaces. Note that OpenCL memory objects may be created from the adapter media surface if and only if the OpenCL context has been created from that adapter. If this extension is supported by an implementation, the string "cl_khr_media_sharing" will be present in the CL_PLATFORM_EXTENSIONS or CL_DEVICE_EXTENSIONS string described in the table of allowed values for param_name for clGetDeviceInfo. As currently proposed the interfaces for this extension would be provided in cl_dx9_media_sharing.h. This section includes the D3D surface formats that are supported when the adapter type is one of the Direct 3D lineage . Using a D3D surface format not listed here is an error. To extend the use of this extension to support media adapters beyond DirectX9 tables similar to the ones in this section will need to be defined for the surface formats supported by the new media adapter. All implementations that support this extension are required to support the NV12 surface format, the other surface formats supported are the same surface formats that the adapter you are sharing with supports as long as they are listed in the two tables below.

Description The char, unsigned char, short, unsigned short, integer, unsigned integer, long, unsigned long, and float vector data types are supported. The vector data type is defined with the type name i.e. char, uchar, short, ushort, int, uint, float, long, or ulong followed by a literal value n that defines the number of elements in the vector. Supported values of n are 2, 3, 4, 8, and 16 for all vector data types. The built-in vector data types are also declared as appropriate types in the OpenCL API (and header files) that can be used by an application. The following table describes the built-in vector data type in the OpenCL C programming language and the corresponding data type available to the application: Type in OpenCL Language Description API type for application charn A vector of n 8-bit signed two's complement integer values. cl_charn ucharn A vector of n 8-bit unsigned integer values. cl_ucharn shortn A vector of n 16-bit signed two's complement integer values. cl_shortn ushortn A vector of n 16-bit unsigned integer values. cl_ushortn intn A vector of n 32-bit signed two's complement integer values. cl_intn uintn A vector of n 32-bit unsigned integer values. cl_uintn longn A vector of n 64-bit signed two's complement integer values. cl_longn ulongn A vector of n 64-bit unsigned integer values. cl_ulongn floatn A vector of n 32-bit floating-point values. cl_floatn doublen A vector of n 64-bit floating-point values. cl_doublen Notes Built-in vector data types are supported by the OpenCL implementation even if the underlying compute device does not support any or all of the vector data types. These are to be converted by the device compiler to appropriate instructions that use underlying built-in types supported natively by the compute device. The double vector type is an optional type that is supported if CL_DEVICE_DOUBLE_FP_CONFIG for a device is not zero. See clGetDeviceInfo. Optional Half Floating Point The half floating-point is supported as an optional extension. An application that wants to use half and halfn will need to include the #pragma OPENCL EXTENSION cl_khr_fp16 : enable directive. This will extended the list of built-in vector and scalar data types to include the following: Type in OpenCL Language Description API type for application half2 A 2-component half-precision floating-point vector. cl_half2 half3 A 3-component half-precision floating-point vector. cl_half3 half4 A 4-component half-precision floating-point vector. cl_half4 half8 An 8-component half-precision floating-point vector. cl_half8 half16 A 16-component half-precision floating-point vector. cl_half16 The relational, equality, logical and logical unary operators can be used with half scalar and halfn vector types and shall produce a scalar int and vector shortn result respectively. The OpenCL compiler accepts an h and H suffix on floating point literals, indicating the literal is typed as a half.

If blocking_read is CL_TRUE i.e. the read command is blocking, clEnqueueReadImage does not return until the buffer data has been read and copied into memory pointed to by ptr. If blocking_read is CL_FALSE i.e. map operation is non-blocking, clEnqueueReadImage queues a non-blocking read command and returns. The contents of the buffer that ptr points to cannot be used until the read command has completed. The event argument returns an event object which can be used to query the execution status of the read command. When the read command has completed, the contents of the buffer that ptr points to can be used by the application. origin Defines the (x, y, z) offset in pixels in the 1D, 2D, or 3D image, the (x, y) offset and the image index in the image array or the (x) offset and the image index in the 1D image array. If image is a 2D image object, origin[2] must be 0. If image is a 1D image or 1D image buffer object, origin[1] and origin[2] must be 0. If image is a 1D image array object, origin[2] must be 0. If image is a 1D image array object, origin[1] describes the image index in the 1D image array. If image is a 2D image array object, origin[2] describes the image index in the 2D image array. region Defines the (width, height, depth) in pixels of the 1D, 2D or 3D rectangle, the (width, height) in pixels of the 2D rectangle and the number of images of a 2D image array or the (width) in pixels of the 1D rectangle and the number of images of a 1D image array. If image is a 2D image object, region[2] must be 1. If image is a 1D image or 1D image buffer object, region[1] and region[2] must be 1. If image is a 1D image array object, region[2] must be 1. row_pitch The length of each row in bytes. This value must be greater than or equal to the element size in bytes * width. If row_pitch is set to 0, the appropriate row pitch is calculated based on the size of each element in bytes multiplied by width. slice_pitch Size in bytes of the 2D slice of the 3D region of a 3D image or each image of a 1D or 2D image array being read. This must be 0 if image is a 1D or 2D image. This value must be greater than or equal to row_pitch * height. If slice_pitch is set to 0, the appropriate slice pitch is calculated based on the row_pitch * height. ptr The pointer to a buffer in host memory where image data is to be read from. event_wait_list , num_events_in_wait_list Specify events that need to complete before this particular command can be executed. If event_wait_list is NULL, then this particular command does not wait on any event to complete. If event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater than 0. The events specified in event_wait_list act as synchronization points. The context associated with events in event_wait_list and command_queue must be the same. The memory associated with event_wait_list can be reused or freed after the function returns. event Returns an event object that identifies this particular read command and can be used to query or queue a wait for this particular command to complete. event can be NULL in which case it will not be possible for the application to query the status of this command or queue a wait for this command to complete. If the event_wait_list and the event arguments are not NULL, the event argument should not refer to an element of the event_wait_list array. Notes Calling clEnqueueReadImage to read a region of the image with the ptr argument value set to host_ptr + (origin[2] * image slice pitch + origin[1] * image row pitch + origin[0] * bytes per pixel), where host_ptr is a pointer to the memory region specified when the image being read is created with CL_MEM_USE_HOST_PTR, must meet the following requirements in order to avoid undefined behavior: All commands that use this image object have finished execution before the read command begins execution. The row_pitch and slice_pitch argument values in clEnqueueReadImage must be set to the image row pitch and slice pitch. The image object is not mapped. The image object is not used by any command-queue until the read command has finished execution. Errors clEnqueueReadImage returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors. CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue. CL_INVALID_CONTEXT if the context associated with command_queue and image are not the same or if the context associated with command_queue and events in event_wait_list are not the same. CL_INVALID_MEM_OBJECT if image is not a valid image object. CL_INVALID_VALUE if the region being read specified by origin and region is out of bounds or if ptr is a NULL value. CL_INVALID_VALUE if values in origin and region do not follow rules described in the argument description for origin and region. CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list > 0, or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects in event_wait_list are not valid events. CL_INVALID_IMAGE_SIZE if image dimensions (image width, height, specified or compute row and/or slice pitch) for image are not supported by device associated with queue. CL_INVALID_IMAGE_FORMAT if image format (image channel order and data type) for image are not supported by device associated with queue. CL_MEM_OBJECT_ALLOCATION_FAILURE if there is a failure to allocate memory for data store associated with image. CL_INVALID_OPERATION if the device associated with command_queue does not support images (i.e. CL_DEVICE_IMAGE_SUPPORT specified in the table of allowed values for param_name for clGetDeviceInfo is CL_FALSE). CL_INVALID_OPERATION if clEnqueueReadImage is called on image which has been created with CL_MEM_HOST_WRITE_ONLY or CL_MEM_HOST_NO_ACCESS CL_EXEC_STATUS_ERROR_FOR_EVENTS_IN_WAIT_LIST if the read and write operations are blocking and the execution status of any of the events in event_wait_list is a negative integer value.
