gpgpu-rs VS naga

If you don't mind using a pure rust "alternative" you could use wgpu or a wrapper like gpgpu-rs, or any other of the projects mentioned in the other comments.

gpgpu-rs is a wgpu helper lib

You could try gpgpu-rs, a compute-focused framework I'm writing. It has some nice integrations with image and ndarray (tho the latter still needs some work) I'll definitely love some feedback :)

Would be really nice to have an actual cross platform GPGPU library. It's really holding every kind of progress back to have only vendor lock-in.

Maybe WebCPU will be capable of compute to the extend that CUDA isn't necessary. https://github.com/UpsettingBoy/gpgpu-rs

gpgpu-rs it is then! 🙂

I'm working on a compute framework (gpgpu-rs) based on wgpu, if you wanna check out.

My recommendation is to stick with WGSL for wgpu. I have some simple compute shaders examples if you wanna check out.

That wouldn't have been all that different from WGSL though, the most important thing is that whatever WebGPU uses for its shaders can be translated to and from SPRIV (and WGSL does that too (e.g. via https://dawn.googlesource.com/tint and https://github.com/gfx-rs/naga).

Hey all, wanted to put this link in here, where I'm proposing changing the API for errors in naga, so Naga can take ownership of error presentation and actually Make Shader Compilation Messages Comfy™: https://github.com/gfx-rs/naga/issues/2317

EDIT: There is also naga but it does not take HLSL as input: https://github.com/gfx-rs/naga but you can use DirectXShaderCompiler to compile to SpirV, then use naga to compile to Metal.

And it seems that naga https://github.com/gfx-rs/naga Already has a working front/backend for wgsl.

This is basically Ray Tracing support in Blade. So far, only ray queries are supported. Unlike prior work on ray tracing in Rust, this is original due to all shader code being WGSL, see the Naga PR.

There's a compiler that can translate from WGSL to SPIR-V called naga. Having such a compiler is essential, since WebGPU is planned to use WGSL and browsers are expected to implement rendering via Vulkan (and probably Metal and DX12).

Not sure about on the CPU, but naga is a shading language transpiler you can write custom front/backends for.

The spec docs are actually pretty useful https://www.w3.org/TR/WGSL/ besides that I was using naga's tests for reference https://github.com/gfx-rs/naga/tree/master/tests

For cross-platform support look at WebGPU and Vulkan (e.g,: [0] [1]. Essentially, you would need to write the func in WGSL or GLSL, HLSL or MSL. Each of these can be cross-compiled to SPIR-V (what Vulkan needs) with cross-compilers such as spirv-cross and naga.
