Scale is a cuda implementation running on nvidia or amdgpu. Think nvcc semantics with template diagnostics by clang.

Nvidia including Spectral in their inception programs seems a big deal to me. It bodes well for the future of the cuda ecosystem.

If you'd like to run it, docs and download at https://scale-lang.com/. It's a clang fork with a bunch of libraries packaged. I'm on the dev team and always happy to hear from people.
