Detailed Description

template<typename Shape_, int Threads, typename WarpThreadArrangement_, int ElementsPerAccess = 1> struct cutlass::transform::PitchLinearWarpStripedThreadMap< Shape_, Threads, WarpThreadArrangement_, ElementsPerAccess >

Policy defining a warp-striped arrangement. This partitions a tile into vectorized memory accesses performed by each warp then distributes warps across them. Warps are striped in the strided dimension and raked across the contiguous dimension.
