What problem does it solve?
Optimizes memory access patterns in a Gluon GEMM kernel across CDNA3/4 GPUs by replacing global loads with AMD-native memory instructions and enabling an LDS-based DMA path on CDNA4 to unlock prefetching.
Core Features & Use Cases
- Step A: Replace gl.load/gl.store with gl.amd.cdna3.buffer_load/buffer_store to reduce branches and address pressure.
- Step B: For CDNA4 gfx950, introduce shared memory (LDS) and use gl.amd.cdna4.async_copy.buffer_load_to_shared to establish a streaming DMA path.
- Use Case: Optimizes large GEMM kernels (e.g., MI300X/MI350) to improve MFMA throughput and reduce latency.
Quick Start
Run gluon-mm-inst-opt to apply Step A and, if on CDNA4 GPUs, Step B to establish an async DMA path from global memory to LDS.
