Nvidia announces native GPU programming in Rust
NVIDIA released CUDA‑Rust, letting you write GPU kernels directly in Rust and compile to PTX. Two programming models are supported: the traditional SIMT model via the `cuda-oxide` backend (nightly Rust, custom codegen) and the newer Tile model via `cutile‑rs` (stable Rust, JIT‑compiled Tile IR). Both provide Rust‑typed safety guarantees (e.g., `DisjointSlice`, tensor partitioning) and simple Carg…

The paper introduces mutation analysis as a quantitative adequacy metric for GPU‑kernel benchmark oracles. By injecting 10,303 deterministic faults into 188 verified CUDA kernels (7,384 with a known kill witness), they show the official KernelBench checker misses 16.9% of faults—especially 78.6% of precision‑related faults. Their analysis quantifies the impact of existing patches (e.g., KernelBen…
