Nvidia brings Rust to GPU kernel programming with CUDA Rust

Nvidia announced CUDA Rust, backed by two open-source NVlabs projects: cuda-oxide, which compiles SIMT kernels from Rust MIR through Pliron and LLVM to PTX, and cutile-rs, which JIT-compiles Tile kernels through CUDA Tile IR on stable Rust 1.89+.

Why it matters: Rust's compile-time memory safety guarantees could eliminate a class of GPU kernel bugs that are costly to debug at scale, and legitimizing Rust as a first-class CUDA language may draw more systems programmers into GPU/AI infrastructure work currently dominated by C++.
