ComputeSharp
A .NET library to run C# code in parallel on the GPU through DX12, D2D1, and dynamically generated HLSL compute and pixel shaders, with the goal of making GPU computing easy to use for all .NET developers! 🚀
> RISC-V
The work is underway: https://github.com/dotnet/runtime/pulls?q=label%3Aarch-riscv
> PTX
https://ilgpu.net/ and even https://github.com/m4rs-mt/ILGPU/blob/c3af8f368445d8e6443f36...
While not PTX, there's also this project: https://github.com/Sergio0694/ComputeSharp which partially overlaps with what ILGPU offers
Arguably, even C++ itself - you are not using "full" C++ but a special subset that works on top of specific abstraction to compile to GPUs, and I was told that CUDA C++ is considered legacy.
The original context of discussion is performance and perceived issue of "having runtime", which is what my reply is targeted at. In that context, C# provides you the tools and a solution other languages in the class of Java, Go, TS and anything else interpreted just don't have. So you could reasonably replace a project written in C++ with C#, and possibly re-apply all the freed-up developer productivity into further optimizations, but you wouldn't be able to do so with the same degree of confidence with most other originally high-level languages. Another upcoming contender is Swift.
