Webcub::BLOCK_STORE_WARP_TRANSPOSE_TIMESLICED. A blocked arrangement is locally transposed into a warp-striped arrangement which is then written to memory. To reduce the shared memory requireent, only one warp's worth of shared memory is provisioned and is subsequently time-sliced among warps. More...

WebAug 26, 2015 · I wrote a warpReduce kernel that has the block size of 32, which allows it to do the whole reduction using shuffle xor. For a 128x100000 for 100 iterations the first version that used 64 blocks per grid (and 32 threads per block) took 0.5s. For the the CUB row reduce it took 0.25s.

WebJul 30, 2015 · 1. If I understood correctly, you want to reduce Object1.lower.x to one result, Object1.lower.y to another result and so on. For any given object there are four arrays to be reduced, all of equal length (for the object). There are many possible approaches to this, one influencing factor would be the total number of objects in your system. how to save snipping tool image as pdfWebcub::WarpReduce< T, LOGICAL_WARP_THREADS, PTX_ARCH > Member List This is the complete list of members for cub::WarpReduce< T, LOGICAL_WARP_THREADS, PTX_ARCH > , including all inherited members.
