NVIDIA AI Just Released cuda-oxide: An Experimental Rust-to-CUDA Compiler Backend that Compiles SIMT GPU Kernels Directly to PTX

Based on the provided documentation, here's a summary of key points for setting up and using CUDA-OXIDE:

Prerequisites

1. Rust Toolchain:

   • Install Rust nightly with rustup install nightly.
   • Ensure you have rust-src and rustc-dev components installed.

2. LLVM 21+:

   • Install LLVM 21 or later.
   • Verify NVPTX backend is present using llc-21 --version.

3. Clang 21:

   • Install full Clang package (clang-21 or libclang-common-21-dev) to provide necessary headers.

4. CUDA Toolkit: Ensure CUDA toolkit is installed and accessible.

5. cargo-oxide:

   • Clone the CUDA-OXIDE repository.
   • Run cargo install --git https://github.com/NVlabs/cuda-oxide.git cargo-oxide outside of the repo, or use cargo oxide run vecadd inside the repo to test setup.

Running Examples

1. vecadd Example:

   bash
    
   1cargo oxide run vecadd

   This will build
