OxiCUDA 0.5.4 adds WarpVec/WarpMask, a SIMD-flavored warp-vector layer for oxicuda-ptx's builder DSL, six new IR instructions for warp shuffle/vote, and a foreign-compiler PTX interop test proving the driver/launch stack hosts upstream rustc-generated PTX too. 38,689 tests, ~1.30M SLoC, 74 crates.
OxiCUDA 0.5.2 fixes a class of PTX portability bugs that CUDA 11.x silently tolerated and CUDA 12.9+ toolchains reject outright (non-ASCII bytes in generated comments), closes several Windows-specific test and lock-contention bugs, and fixes a numerical-correctness bug in the tensor-network DMRG excited-states solver. 38,675 tests, ~1.30M SLoC, 74 crates.
OxiCUDA 0.5.1 adds oxicuda-nvrtc, a pure-Rust runtime loader for NVIDIA's NVRTC CUDA-C-to-PTX JIT compiler, completing the zero-SDK-dependency story alongside oxicuda-driver. Graceful degradation, process-wide caching, and direct PTX handoff to oxicuda-driver. 38,646 tests, ~1.30M SLoC, 74 crates.
OxiCUDA 0.5.0, the sovereign GPU-compute layer for the COOLJAPAN ecosystem, fixes F64-precision PTX codegen bugs that made ptxas reject elementwise and reduction kernels, closes a mixed-precision GEMM accumulator bug, and hits zero unwrap()/expect() in library code. 38,622 tests, ~1.30M SLoC, 73 crates.
OxiCUDA 0.4.0 is an on-device validation pass: for the first time, hand-written PTX across 60+ crates was JIT-compiled and run on real NVIDIA hardware (RTX A4000, sm_86, CUDA 12.4) instead of only checked for CPU-logic parity — catching register-shadowing bugs, base-2/base-e math errors, invalid PTX, and literal stub kernels. 38,093 tests passing, ~1.27M SLoC, 73 crates.
Pure-Rust replacement for the entire NVIDIA CUDA Toolkit. 0.1.7 adds a SYR2K Tensor Core kernel (fused A×Bᵀ + B×Aᵀ rank-2k update) to oxicuda-blas, cross-subsystem CUDA kernel enhancements, and Multi-Operation Scheduling improvements. No CUDA SDK, no nvcc, no C/C++ toolchain.
Pure-Rust replacement for the NVIDIA CUDA Toolkit. OxiCUDA 0.1.6 adds a Tensor Core fast path for SYRK in oxicuda-blas and sixteen new ML crates (adversarial, SSL, continual, multimodal, 3D geometry, PINN, ANN, anomaly, causal, meta, MoE, NeRF, quantum, recsys, RLHF, tabular). No CUDA SDK, no nvcc.
Complete, type-safe, memory-safe rewrite of the entire NVIDIA CUDA Toolkit in pure Rust. cuBLAS/cuDNN/cuFFT/cuSPARSE/cuSOLVER/cuRAND and more — all in 253k SLoC across 28 crates. Only runtime dependency is the NVIDIA driver. PTX codegen + autotuner, 7 GPU backends (Metal/Vulkan/WebGPU/ROCm/LevelZero). ≥90–95% of native CUDA performance. The sovereign GPU computing layer for SciRS2 and the entire COOLJAPAN ecosystem (now 21M+ SLoC total).
OxiCUDA 0.1.0 is a pure-Rust, type-safe, memory-safe replacement for the entire NVIDIA CUDA Toolkit software stack — cuBLAS, cuDNN, cuFFT, cuSPARSE, cuSOLVER, cuRAND and more in ~239K lines across 28 crates. The only runtime dependency is the NVIDIA driver. PTX code generation plus a built-in autotuner, all from safe Rust.
