Detailed Description

template<typename Shape_, typename Count_, int Threads, int ElementsPerAccess, int ElementSize> struct cutlass::epilogue::threadblock::OutputTileOptimalThreadMap< Shape_, Count_, Threads, ElementsPerAccess, ElementSize >

Template metaprogram for partitioning a 4D space across warps to achieve several performance objectives:

• coalesced memory accesses in units of 128 Byte lines
• minimal address arithmetic
• minimal predicate calculations
