WebOct 6, 2024 · I see this issue for old cuda versions, but haven't seen a clear answer for that. 推荐答案. Warp shuffle intrinsics are only defined (only supported on) compute capability (cc) 3.0 architectures and higher. After CUDA 8.0, those were the only GPUs supported by nvcc, so even if you compile for default architecture (3.0) it will compile ... WebMay 13, 2024 · On Wednesday, May 13, 2024, NVIDIA will present part 5 of a 9-part CUDA Training Series titled “Atomics, Reductions, and Warp Shuffle”.

WebJan 27, 2024 · You can reduce the pressure on shared memory here, by converting the reduction to use a similar warp-shuffle based reduction methodology. Because this involves multiple warps in this second phase of your kernel activity, the code is a two-stage warp-shuffle reduction.

WebFeb 3, 2014 · The typical way to do this in CUDA programming is to use shared memory. But the NVIDIA Kepler GPU architecture introduced a way to directly share data between threads that are part of the same warp. On Kepler, threads of a warp can read each others’ registers by using a new instruction called SHFL, or “shuffle”.
