CUDA Shuffle Instruction (Warp-level intra register exchange)

WebAn NVIDIA 8 Series GPU executes warps of 32 threads in parallel. Because not all threads run simultaneously for arrays larger than the warp size, Algorithm 1 will not work, because it performs the scan in place on the array. The results of one warp will be overwritten by threads in another warp. WebNov 22, 2024 · Thereafter the warp shuffle proceeds for the current state of the warp. There is no other implied behavior.
