GoKawiilNvidia adds native Rust support for writing CUDA GPU kernels
Nvidia announced it is extending CUDA to support GPU kernels written natively in Rust, compiled directly to PTX rather than wrapped around another language. The move covers both the existing SIMT model used in CUDA C++ and Python, and the newer Tile programming model, with development continuing into 2027.
GoKawiil's interpretation of the reporting above, not reported fact.
Rust has already spread through AI infrastructure—drivers, serving systems, and runtimes—because it catches memory and concurrency bugs at compile time without sacrificing speed, but GPU kernels remained one of the last holdouts written in other languages. By closing that gap, Nvidia lets developers build safer, fully Rust-based GPU software stacks without needing interop hacks or rewrites in C++ or Python.
- Nvidia is building native Rust kernel compilation directly to PTX for CUDA.
- Both SIMT and the newer Tile programming models will be supported in Rust.
- Nvidia plans cross-language interop so Rust adoption won't lock out C++ or Python users.
NVIDIA GeForce RTX 4070 GPU — If you're diving into CUDA Rust and native GPU kernel programming, having a capable CUDA-enabled GPU on your desk makes local development and testing far smoother. The RTX 4070 offers solid CUDA core counts and memory for experimenting with SIMT and Tile programming models without needing cloud compute. It's a great entry point for developers wanting hands-on experience with NVIDIA's evolving Rust toolchain.
