Let's count abstraction layers: 1. Domain specific Rust code 2. Backend abstracting over the cust, ash and wgpu crates 3. wgpu and co. abstracting over platforms, drivers and APIs 4. Vulkan, OpenGL, DX12 and Metal abstracting over platforms and drivers 5. Drivers abstracting over vendor specific hardware (one could argue there are more layers in here) 6. Hardware That's a lot of hidden complexity, better hope one nev…

The demo is admittedly a rube goldberg machine, but that's because this was the first time it is possible. It will get more integrated over time. And just like normal rust code, you can make it as abstract or concrete as you want. But at least you have the tools to do so. That's one of the nice things about the rust ecosystem, you can drill down and do what you want. There is std::arch, which is platform specific, th…

They said the same thing about browser tech. Still not simpler under the hood.

Because folks like to program in Rust, not CUDA

"Folks" as-in Rust stans, whom know very little about CUDA and what makes it nice in the first place, sure, but is there demand for Rust ports amongst actual CUDA programmers? I think not.

What makes cuda nice in the first place?

All the things marked with red cross in the Rust-CUDA compatibility matrix.

FYI, rust-cuda outputs nvvm so it can integrate with the existing cuda ecosystem. We aren't suggesting rewriting everything in Rust. Check the repo for crates that allow using existing stuff like cudnn and cuBLAS.

As far as I understand, there was a similar mess with CPUs some 50 years ago: All computers were different and there was no such thing as portable code. Then problem solvers came up with abstractions like the C programming language, allowing developers to write more or less the same code for different platforms. I suppose GPUs are slowly going through a similar process now that they're useful in many more domains than just graphics. I'm just spitballing.

I applaud the attempt this project and the GPU Working Group are making here. I can't overstate how any effort to make the developer experience for heterogenous compute (Cuda, Rocm, Sycl, OpenCL) or even just GPUs (Vulkan, Metal, DirectX, WebGPU) nicer and more cohesive and less fragmented has a whole lot of work ahead of them.

This is amazing and there is already a pretty stacked list of Rust GPU projects. This seems to be at an even lower level of abstraction than burn[0] which is lower than candle[1]. I gueds whats left is to add backend(s) that leverage naga and others to the above projects? Feeks like everyone is building on different bases here, though I know the naga work is relatively new. [EDIT] Just to note, burn is the one that f…

You can check out https://rust-gpu.github.io/ecosystem/ as well, which mentions CubeCL.
