/*
* Stateless universal device GEMM kernel type that treats GEMM as
* a composition of a collective mainloop and a collective epilogue.
*
* Supports both the 2.x and 3.x APIs based on whether the first type is
* a cute::tuple<> or not.
* 2.x API implementation: cutlass/gemm/kernel/gemm_universal.h
* 3.x API implementation: cutlass/gemm/kernel/gemm_*.hpp
*
* In the following declaration, the name preceding the 'Or' refers to
* 3.x API type argument order, and the name succeeding the 'Or' refers to
* 2.x API type argument order. Template arguments without two names
* belong to the 3.x API only.
