CUDA is NVIDIA's language for GPU programming, allowing you to mix write CPU and GPU code in C++ in one file. By chaining a few projects that compile CUDA to OpenCL, then Vulkan, then WebGPU, you can experiment with this GPGPU language on any hardware.

I love the idea of this, but sadly I can't get it to work in Firefox, Chrome or Edge on my work pc, probably because I can't find "--enable-features=Vulkan" equivalent in the about:flags and the argument doesn't appear to work on windows. I'm actually a bit more curious about a standalone application that skips the webgpu part and goes straight to Vulkan as I would love to be able to experiment with some Cuda only applications.

I don't currently expose the option to run the compiler if a GPU isn't detected, but on systems that do, it exposes a download option that lets you download the SPIR-V kernel to run with Vulkan.

I got a `Uncaught (in promise) TypeError: WebAssembly compilation aborted: Network error: Response body loading was aborted` error the first time, but after a reload it worked.
