Pure Rust FFT and the rustfft replacement. OxiFFT 0.4.0 adds distributed real (r2c/c2r) MPI transforms, wires wisdom-based auto-tuning into MEASURE/PATIENT/EXHAUSTIVE planning so it really compares candidate algorithms, corrects the MSRV to 1.87, and ships a breaking cleanup of dead planner code plus a v2 wisdom binary format.
Pure Rust FFT and the rustfft replacement. OxiFFT 0.3.2 completes multi-rank MPI execution for the 3D pencil decomposition, gates AVX-512 codelets behind a default-off feature so the build stays clean on rustc 1.95 stable, hardens ND-plan error handling, and refreshes the OxiCUDA GPU backend.
Pure Rust FFT and the rustfft replacement. OxiFFT 0.3.0 lands an FFT-based Makhoul DCT (~4× flop reduction), a 7-gate FFTW parity harness, GPU batch FFT with auto-chunking, 3D pencil MPI, a cache-oblivious 4-step transform, and real WASM SIMD v128 — 1360 tests passing, default build still 100% Rust.
