Motivation
Add MXFP4 data generator for Tensile
Technical Details
Integrate Hipblaslt’s MXFP4 data generator into TensilteLite.
The goal is to decrease the amount of zero-valued data so that it better resembles production workloads, thereby improving real‑time performance accuracy.
After integration, zero frequency drops by 0.5%, and stays in the range of ~12.5%-13%.
Note: Upgrades to C++20 as mxDataGenerator requires it.
Test Plan
MXDataGen_test.cpp - verify the integration works & that the zero frequency is below a fixed threshold.
Test Result
TBD
