Description

Hi:
I'd like to test FP8 in RTX 4090. I can find some BF16 functions like SM80_16x8x8_F32BF16BF16F32_TN in cutlass/include/cute/arch/mma_sm80.hpp, however, I can't find some FP8 functions like SM80_16x8x8_F32E4M3E4M3FP32_TN. So, how to implement SM80_16x8x8_F32E4M3E4M3FP32_TN?
Thank you~

Research direction

Start by reading cutlass/include/cute/arch/mma_sm80.hpp and comparing the existing SM80 BF16 function with the requested FP8 function. Check how FP8 support maps to the RTX 4090's Ada Lovelace architecture; done means establishing whether the requested operation is supported and documenting or implementing the appropriate path.
