Hello!
In Cutlass 3.5.1 OpMultiplyAdd substitutions for s8/s4 types were removed, only OpMultiplyAddSaturate stay.

3.5.0 version
3.5.1 version

Cases seems identical (use same mma instructions), but this change:

  1. Breaks backward compatibility
  2. Makes coding more confusing - you are not expecting to use OpMultiplyAddSaturate when do int4/int8 GEMM's.

Is it bug or intended decision, which will not be fixed?

Thanks
