WebIf 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. WebCategory: OpenCL™ Tools: Intel® FPGA SDK for OpenCL™ device:-During kernel execution, printf data is stored in a global printf buffer that is automatically allocated by the Intel FPGA SDK for OpenCL™ Offline Compiler. The size of this buffer is 64 KB, so the total size of the data arguments in the printf call should not exceed this size.

WebMapping buffer objects. OpenCL provides a mechanism to map a region of a buffer directly into host memory instead of using the clEnqueue [Read Write]Buffer functions. These mapped regions can be returned to the application. The application can use this mapped memory region based on the cl_map_flags flag value which is set during mapping. http://man.opencl.org/clEnqueueMapBuffer.html

WebApplying Shared Local Memory. Intel® Graphics device supports the Shared Local Memory (SLM), attributed with __local in OpenCL™. This type of memory is well-suited for scatter operations that otherwise are directed to global memory. Copy small table buffers or any buffer data, which is frequently reused, to SLM.
