Attention Decode on AMD MI450 GPUs: A Gluon Kernel Optimization Guide
Summary
A ROCm blog post analyzing attention decode workloads on AMD MI450 GPUs and presenting a Gluon-based kernel optimization guide. It covers MI450 hardware features (including TDM, larger LDS and registers, and workgroup clusters), four optimization areas (tensor layout, data loading, latency-hiding pipelines, and Split-k), and reports bandwidth-driven performance results up to 85% of peak HBM bandwidth on MI450.
