March 2026 performance summary focused on expanding CDNA3 benchmark coverage, stabilizing critical paths, and strengthening CI and tooling to deliver measurable business value across MGPSim and Akita. Key work included expanding CDNA3 support for BFS/NW, FFT, SPMV, and N-body benchmarks, plus substantial fixes to CDNA3 struct layouts, FLAT offset decoding, and HSACO integration. Stencil2D CDNA3 page fault and kernel descriptor metadata were resolved, with acceptance tests added to validate end-to-end correctness. The N-body CDNA3 fix used a safer GCN3 kernel path to eliminate data races and simplify usage. In Ares, we introduced -bytes flag support, CLI flag for FFT benchmarking, FFT sub-MB sizes, and timing model sync for M2.1 benchmarks, along with a DRAM modeling update via simplebankedmemory and CI/linter improvements, increasing reliability and throughput of benchmarks. MI300A calibration achieved 16.4% WMAPE accuracy across 206 matched points, signaling improved timing and memory behavior models. Cross-repo, Akita upgraded the SQLite driver to glebarez/go-sqlite (pure Go) for better compatibility and performance. Overall impact: broader hardware coverage, higher correctness, faster feedback loops, and improved stability that directly supports faster decision-making and more reliable performance projections.
