NVIDIA Releases cuda-oxide: Experimental Rust-to-CUDA Compiler

NVlabs released cuda-oxide v0.1.0 on May 9, 2026, an experimental Rust-to-CUDA compiler backend that compiles GPU kernels directly to PTX. The custom rustc codegen backend uses a Rust → Stable MIR → Pliron IR → LLVM IR → PTX compilation pipeline to transform #[kernel]-annotated Rust functions into SIMT GPU kernels. The tool enables single-source host and device compilation from a single cargo oxide build command.
