WebShared memory is a CUDA memory space that is shared by all threads in a thread block. In this case shared means that all threads in a thread block can write and read to block-allocated shared memory, and all changes to this memory will be eventually available to all threads in the block. WebNov 10, 2024 · You can define blocks which map threads to Stream Processors (the 128 Cuda Cores per SM). One warp is always formed by 32 threads and all threads of a warp are executed simulaneously. To use the full possible power of a GPU you need much more threads per SM than the SM has SPs.
