\brief
|
|
Default kernel-level GEMM definitions combine threadblock-scoped matrix multiply-add with
|
|
the appropriate threadblock-scoped epilogue.
|
|
|
|
Note, CUTLASS epilogues universally target row-major outputs. Column-major outputs are
|
|
accommodated by exchanging A and B operands and assuming transposed layouts. Partial
|
|
specializations here choose 'device::GemmTransposed' to implement this functionality.
