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.

Project mention: PeachPie Compiler: Compile and run PHP on top of .NET runtime | news.ycombinator.com | 2024-10-08
we have attempted to use it for that, but it was really hard and we ended up rewriting from scratch.
The activity graph on GitHub says it is mostly dead. There is some activity, but at best it is in maintenance mode. It used to be sponsored, but not anymore IIRC

I think it's a useful insight for people working on RAG using LLMs.
Devs working on RAG have to decide between parsing PDFs or using computer vision or both.
The author of the blog works on PdfPig, a framework to parse PDFs. It seems to rely on combining computer vision with PDF metadata for its document understanding APIs. https://github.com/UglyToad/PdfPig/wiki/Document-Layout-Anal...
GP's comment says a pure computer vision approach may be more effective in real-world scenarios, which is an interesting insight since many devs would assume that pure computer vision is probably the less capable but also more complex approach.
As for comments suggesting relying on the parsing library itself instead of rasterizing, the reason is that detecting high-level visual objects (like tables , headings, and illustrations) and getting their coordinates using vision models is far easier that trying to infer those structures by examining hundreds of PDF line, text, glyph, and other low-level PDF objects. I feel these commentators have never tried raw PDF parsing. Try it once using PdfBox, Fitz, etc. You'll understand the difficulty. PDF really is a terrible format!
