Cuda shuffle reduce

WebStarting with the Kepler GPU architecture, CUDA provides shuffle (shfl) instruction and fast device memory atomic operations that make reductions even faster. Reduction kernels that the GPU Coder creates use the shfl_down instruction to reduce across a warp (32 threads) of threads. Then, the first thread of each warp uses the atomic operation ...
