A demo showcases a unified Rust codebase that can run on various GPU platforms, including CUDA, SPIR-V, Metal, DirectX 12, and WebGPU, without relying on specialized shader or kernel languages. This achievement is made possible through collaborative projects like Rust GPU, Rust CUDA, and Naga, enabling seamless cross-platform GPU compute. While still in development, this milestone demonstrates Rust's potential for GPU programming and enhances developer experience by simplifying the coding process.

The article introduces Cuq, a framework that translates Rust's Mid-level Intermediate Representation (MIR) into Coq, aiming to establish formal semantics for Rust GPU kernels compiled to NVIDIA's PTX. It addresses the lack of verified mapping from Rust's compiler IR to PTX while focusing on memory model soundness and offers a prototype for automating this translation and verification process. Future developments may include integrating Rust's ownership and lifetime reasoning into the framework.
