WebFeb 8, 2016 · CUDA warp shuffleは,kepler世代のcc3.x以上から使える, shared memoryを用いずに, warp 内のthread間で値を交換することができる機能です. GPGPU では,shared memoryをいじるのが当然なのですが,それをせずにさらに高速化することができるということで,使えるようになっておきたい機能です. 関数は4つ用意されて … 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.
