Description
Hi,
I tested this file examples/55_hopper_mixed_dtype_gemm/55_hopper_int4_fp8_gemm.cu,
and it shows about a 10%-20% performance improvement under some input sizes.
Is there a plan for supporting Scale with zero-point mode?
Thank you.

Research direction
Start with examples/55_hopper_mixed_dtype_gemm/55_hopper_int4_fp8_gemm.cu and review how the example currently handles Scale. Investigate the requested zero-point mode and its support requirements across the relevant GEMM implementation and tests. Done means establishing and implementing support for Scale with zero-point mode, with coverage demonstrating it works.
