It really is a tiny subset of the C++ standard library, but I'm happy to see they're continuing to expand it: https://nvidia.github.io/libcudacxx/api.html

Nvidia has had many members on the c++ standards committee for a while.

I'm not sure how making a large contribution to the C++ Standard is a problem?

Yeah, really tiny... At first I thought 'wow this is a game changer', but then I looked at your link and thought 'what's the point?'. Can someone explain what real problems you can solve with just the headers in the link above?

I guess that the point is that when writing CUDA code (which looks like C++), you can use these libraries which are homogenous with CPU code.

Looking at the functions, chrono/barrier etc require CPU level abstractions, so using the STL versions (which are for the CPU) aren't going to work really.

It runs on the GPU?

I would have expected the <algorithm> header, but instead...synchronization primitives? std::chrono? I'm completely baffled about how that would be useful, but that's probably because I know very little about CUDA.

Today, you can use the library with NVCC, and the subset is small. We'll be focusing on expanding that subset over time.

Our end goal is to enable the full C++ Standard Library. The current feature set is just a pit stop on the way there.
