Opencl local memory大小
Web__local Memory Local memory can be used to avoid multiple redundant reads from and writes to global memory. But it is important to note that the SLM (which is used to implement local memory), occupies the same place in the architecture as the L3 cache. So the performance of local memory accesses is often similar to that of a cache hit. You then set the kernelargument with a value of NULL and a size equal to the size you want to allocate for the argument (in byte). Therefore it should be: clSetKernelArg (kernel, 2, length * sizeof (cl_float), NULL); clSetKernelArg (kernel, 3, height* sizeof (cl_float), NULL); local memory is always shared by the workgroup (as opposed to ...

WebWork-Group Size Recommendations Summary. If your kernel uses local memory and/or barriers, the actual number of work-groups that can run simultaneously on one of the Intel® Graphics sub-slice is limited by the following key factors: There are 16 barrier registers per sub-slice, so no more than 16 work-groups can be executed simultaneously.

In the figure above, each workgroup size is 8×4 comprising a total of 32 work-items. Work-items in a workgroup can synchronize with one another and share data using local memory (to be explained in a later article). OpenCL execution on the PowerVR Rogue architecture
WebSchool of Computing ANU School of Computing WebIntel® 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.
