deno_webgpu

This op crate implements the WebGPU API as defined in https://gpuweb.github.io/gpuweb/ in Deno. The implementation targets the spec draft as of March 31, 2024. The spec is still very much in flux. This extension tries to stay up to date with the spec, but is constrained by the features implemented in our GPU backend library wgpu.

The spec is still very bare bones, and is still missing many details. As the spec becomes more concrete, we will implement to follow the spec more closely.

In addition, setting the DENO_WEBGPU_TRACE environmental variable will output a wgpu trace to the specified directory.

This op crate is tested primarily by running the WebGPU conformance test suite using wgpu's cts_runner. cts_runner also has a few directed tests to fill in missing coverage.

GPU availability in GitHub CI is limited, so some configurations rely on software like DX WARP & Vulkan lavapipe.
