WebNvidia's CUDA (Compute United Device Architecture) platform provides a scalable programming model for GPU computation, where tens of thousands of concurrent threads offered by a modern GPU are organized in a hierarchy of thread groups. The top-level is called Grid, which is composed of many equal-sized (i.e., the same number of threads) … 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.

WebThe CUDA analogs of threadid and nthreads are called threadIdx and blockDim, respectively; one difference is that these return a 3-dimensional structure with fields x, y, and z to simplify cartesian indexing for up to 3-dimensional arrays. Consequently we can assign unique work in the following way: WebOnce a kernel is launched, the CUDA runtime system generates the corresponding grid of threads. As discussed in the previous section, these threads are assigned to execution resources on a block-by-block basis. In the current generation of hardware, the execution resources are organized into Streaming Multiprocessors (SMs).
