__local Memory - Intel

WebTo see how the work-group dimensions can affect memory bandwidth, consider the following code segment: __global int* myArray = ...; uint myIndex = get_global_id (0) + get_global_id (1) * width; int i = myArray [ myIndex ]; This is a typical memory access pattern for a two-dimensional array. Consider three possible work-group dimensions, … WebAssuming that global memory latency is hidden by running enough work-items per multiprocessor, the next optimization to focus on is maximizing the kernel’s overall memory throughput. This is done by maximizing the use of high bandwidth memory (OpenCL local and constant memory, Section 3.3 of OpenCL specification) and by using the proper notes for jewish songs https://roofkingsoflafayette.com
