I've built a demo of a single shared Rust codebase that runs on every major GPU platform:

• CUDA for NVIDIA GPUs
• SPIR-V for Vulkan-compatible GPUs from AMD, Intel, NVIDIA, and Android devices
• Metal for Apple devices
• DirectX 12 for Windows
• WebGPU for browsers
• CPU fallback for non-GPU systems

The same compute logic runs on all targets, written entirely in regular Rust. No shader or kernel languages are used.

I used AI to port virtually all of the shaders from Sascha Willems' popular Vulkan sample repo over to Rust using Rust GPU. This demonstrates Rust GPU is ready for production use.

With AI handling most of the codegen and me reviewing and tweaking the results, the port took about four days of part-time work—a 30x speedup compared to Sascha's manual port to Slang.

Rust CUDA enables you to write and run CUDA kernels in Rust, executing directly on NVIDIA GPUs using NVVM IR.

Work is ongoing in the project and we wanted to share an update.

We ported a few popular Shadertoy shaders over to Rust using Rust GPU. The process was straightforward and we want to share some highlights.

The Rust CUDA project has been rebooted after being dormant for 3+ years.

Rust CUDA enables you to write and run CUDA kernels in Rust, executing directly on NVIDIA GPUs using NVVM IR.

Much has happened since the reboot announcement and we wanted to give an update.

We're excited to announce the reboot of the Rust CUDA project. Rust CUDA enables you to write and run CUDA kernels in Rust, executing directly on NVIDIA GPUs using NVVM IR.

Our immediate focus is on modernizing the project and integrating with other GPU-related efforts in the Rust ecosystem.

I read the excellent post Optimizing a WebGPU Matmul Kernel for 1TFLOP+ Performance by Zach Nussbaum and thought it might be fun to reimplement it with Rust GPU.

We'll follow Zach's original post closely, comparing and contrasting using Rust vs the WGSL and Typescript from his post.

At the end, I'll show some unique benefits of using Rust on the GPU.

We’re thrilled to introduce two new maintainers for the Rust GPU project: Schell Scivally and Firestar99.

Both bring experience in graphics programming, a deep understanding of Rust, and a passion for advancing GPU computing.

We are excited to announce that as of today the Rust GPU project will be transitioning from Embark Studios to community ownership under the Rust GPU GitHub organization. This move marks the beginning of a broader strategy aimed at revitalizing, unifying, and standardizing GPU programming in Rust. We are eager to share more details in the near future but in the meantime if you are a maintainer of a GPU-related Rust project, please reach out!
