What problem does it solve?
Two-stage pipeline optimizations to hide global memory latency and LDS read latency in Gluon GEMM kernels on CDNA3 (gfx942) and CDNA4 (gfx950) GPUs, enabling higher MFMA throughput and better occupancy.
Core Features & Use Cases
- Stage 1: Global prefetch with double buffering to overlap data loads with compute across CDNA3/CDNA4 variants.
- Stage 2: Local prefetch to overlap ds_read with MFMA, architecture-agnostic.
- Use Case: Optimizing a Gluon GEMM kernel on MI300X/MI350 class GPUs to reduce vmcnt/lgkmcnt stalls and improve MFMA efficiency.
Quick Start
Apply Stage 1 to your kernel, verify correctness, then consider Stage 2 to further hide remaining stalls.
