Rust on Every GPU

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

CUDA for NVIDIA GPUs

for NVIDIA GPUs SPIR-V for Vulkan-compatible GPUs from AMD, Intel, NVIDIA, and Android devices

for Vulkan-compatible GPUs from AMD, Intel, NVIDIA, and Android devices Metal for Apple devices

for Apple devices DirectX 12 for Windows

for Windows WebGPU for browsers

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.

The code is available on GitHub.

GPUs are typically programmed using specialized languages like WGSL, GLSL, MSL, HLSL, Slang, or Triton. These languages are GPU-specific and separate from the host application's language and tooling, increasing complexity and duplicating logic across CPU and GPU code.
