Comment on Gpu.cpp: A lightweight library for portable low-level GPU computationparent

Comments

I know you said elsewhere in this thread that you want to focus on a single WebGPU runtime for the moment, but I just want to plug how easy it is to build wgpu even as a submodule of a C++ project. I had a demo integrated into my project in less than an hour of tinkering with CMake.

Yes wgpu is a much lighter build and has a lot going for it.

The situation has gotten a lot better for both dawn and wgpu integration in C++ with:

Getting a shared library build was a revelation though, credit to:

https://github.com/jspanchu/webgpu-dawn-binaries

because the FetchContent cache invalidations would still periodically lead to recompiling which gets quite annoying. When it's just a matter of linking you get few-second builds consistently. The cost is we'll have a bit of hardening around potential ABI bugs but it's ultimately worth it.

We'll work towards wgpu support. There's some sharp edges in the non-overlap w/ dawn which seem most pronounced with the async handling (which is pretty critical), but I don't think anything is a hard blocker.

WebGPU-distribution is news to me; thanks for the link!
