BenchmarkTools suite covering the HPTT/TTC reference cases, small sizes (including the strided-rs cases), and non-SIMD-aligned sizes, over element types and thread counts, configurable via ArgParse. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Cases (and per-group sampling parameters) now live in benchmark/cases.toml; an alternative file can be passed with --cases. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…trided views Cases now fix a shape (dimension ratios) and permutation and sweep a list of total lengths, so each can be normalized against a same-length memory copy (auto-generated `copy` group) for a machine-independent efficiency. Adds a `strided` group whose inputs/outputs are genuinely non-contiguous strided views (non-unit leading and second-leading strides), replacing the explicit-size hptt/small/unaligned groups. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Adds a BenchmarkTools.jl suite at
benchmark/benchmarks.jl(definingSUITE) for trackingpermutedims!performance across revisions with AirSpeedVelocity.jl.Each case fixes a shape (dimension ratios) and a permutation and is swept over a list of total lengths, so its time can be divided by that of a same-length memory copy (the auto-generated
copygroup) for a machine-independent efficiency (≥ 1, approaching1when bandwidth-bound).
