https://docs.rs/em contains not only documentation but also comprehensive explanation on effectively using Emu.
I would recommend looking through it first. Of course, if you have questions feel free to ask - https://gitter.im/talk-about-emu/thoughts

- Maybe there is a component of RLSL that could be useful. I have to think more about what I want that component to be.
- I want Emu to support general Rust code but still use stable Rust and provide really nice compile-time errors. Maybe Emu could do AST-level checking to (1) ensure that only legal transpilable-to-SPIR-V subset is used, (2) infer the kernel parameters, (3) infer global work size, local work size and then do MIR-level compilation to OpenCL or SPIR-V?
- At the moment, I want to focus on AST-level compilation because I think many applications (AI, ML, simulations, etc.) can still technically be implemented without a huge subset of Rust.

I've been working on a project with similar goal to RLSL, called Emu. It's a procedural macro that automatically off-loads portions of code to run on a GPU. Here's a quick example...
#[gpu_use]
fn main() {
let mut a = vec![0.2; 1000];
let mut b = vec![0.3; 1000];
let c = vec![0.0; 1000];
gpu_do!(load(a));
gpu_do!(load(b));
gpu_do!(load(c));
gpu_do!(launch());
for i in 0..1000 {
c[i] = a[i] + b[i];
}
gpu_do!(read(c));
println!("{:?}", c);
}
So if you're looking for a way to contribute to single-source GPGPU for Rust, please consider helping expand Emu's supported subset of Rust. The repository is at https://www.github.com/calebwin/emu
I will say that since Emu works at the AST/syntax level, RLSL is of great interest to me because it works instead at the MIR level which allows it to more easily support a large subset of Rust.

Would you mind elaborating on the "compile time reference counting"?
Is this new?
How does it handle cycles?

I really like that graphic for the website and README!
Did you make it?
