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). 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) … cherubim with wheels
