Julia has had a great CUDA story for a few years now, and this about 9 days old. Rust rejects buffer aliasing at compile time using Rust's borrow checker, but shared memory in cuda-oxide currently requires unsafe, but then there's HuggingFace's Grout and mistral.rs, so yeah, Rust is picking up ground here on Julia. How is OpenCL's performance these days?

I highly recommend Julia for (scientific) GPU programming but it would be nice if there was a larger community and/or funding behind the GPU side of things. It has very few core devs for what it is.
