Summary: This Diff improves FP8 tensorwise GEMM performance with scalar scale broadcasting along with EVT - **FP8 CUTLASS tensorwise is 15% faster than FP8 CUTLASS rowwise GEMM on average (up to 2.7x faster)** - Before this Diff, FP8 tensorwise CUTLASS GEMM is similar to FP8 rowwise - FP8 tensorwise would be useful in models that are not very sensitive to numeric variance, while require latency/throughput boost (e.g., LLM with 7B, LDM, etc) - More data can be found in [this data sheet](https://docs.google.com/spreadsheets/d/1SYSjYqWeESasl9LII-qHLHMvaNAXlV5wmCV9BWIrKBc/edit?usp=sharing) {F1636238658} TODO 1. Merge two FP8 tensorwise GEMMs into one 2. Support e5m2 for bwd and bias Differential Revision: D57263833
