Cuda thread grid diagram

WebJul 11, 2024 · Conventional wisdom is that the number of threads in the grid for a grid-stride loop should be sized to roughly match the thread-carrying capacity of the GPU in question. The reason for this is to maximize the exposed parallelism, which is one of the 2 most important objectives for any CUDA programmer. WebEvery thread in CUDA is associated with a particular index so that it can calculate and access memory locations in an array. Consider an example in which there is an array of …
