ndarray v0.2.3 (go-ndarray/ndarray#20) adds VSX SIMD kernels on ppc64le. - performance.md: re-synced verbatim from docs/perf.md at v0.2.3 (new section 'ppc64le: VSX kernels (2026-10-04)' and the SIMD coverage update); the summary is now 'Where it stands at v0.2.3', names amd64, arm64 and ppc64le and gives the POWER9 GEMM figures from that section. - index.md: SIMD on amd64, arm64 and ppc64le, worded as the ndarray README at v0.2.3 (max/min SIMD on amd64 only, VSX 8x8 micro-kernel). - roadmap.md: the 'Today (v0.2.1)' sentence and the 'other four targets' clause no longer leave ppc64le on scalar code.

go-ndarray/ndarray v0.2.3 (go-ndarray/ndarray#20) adds VSX SIMD kernels on ppc64le (sum, dot, sqrt, add/sub/mul/div, an 8x8 GEMM micro-kernel; max/min stay scalar).
docs/perf.mdat v0.2.3 (adds ppc64le: VSX kernels (2026-10-04) and the SIMD-coverage update). The summary block now reads Where it stands at v0.2.3, says SIMD kernels exist on amd64, arm64 and ppc64le, and quotes the POWER9 figures from that section (serial GEMM 7.9 → 15.8 GFLOP/s, 0.69× OpenBLAS 0.3.34 serial, 0.56× for MatMul 1024² on 32 threads).docs/plan-ndarray.md(it carries docs-only passages from earlier syncs);plan-ndarray.mdat v0.2.3 did not change and still says the other four targets, which is stale upstream.mkdocs build --strictpasses locally.🤖 Generated with Claude Code
