[QST] thread num assert in sm70_epilogue_vectorized

[mammoth831]

Hi, @thakkarV

cutlass/include/cutlass/epilogue/collective/sm70_epilogue_vectorized.hpp

Line 237 in 47a3ebb

CUTE_STATIC_ASSERT(typename TiledCopyS2R::TiledNumThr{} == size<0>(typename TiledMma::AtomLayoutC_TV{}));

Strangely, it requires TiledCopyS2R's threads equal to the MMA AtomC's threads. I think here we describe how each thread does LDS and therefore it should be:

CUTE_STATIC_ASSERT(typename TiledCopyS2R::TiledNumThr{} == thr_size(typename TiledMma{}));
