What happened
Summary: Pull Request resolved: #200788 This diff adds opt-in round-to-nearest-even preprocessing for native FP32 GEMMs on AMD gfx942 so MI300 TF32 input conversion tracks NVIDIA TF32 semantics. The path is private and controlled by TORCH_GFX942_ENABLE_RN=1 ; unset or 0 preserves current behavior. Context: T16 NVIDIA-to-AMD parity validation found a significant dpa_product_cvr_model NE increase only on MI300 with TF…
