Here is a demo of a backend for a Process-In-Memory chip. It is a demonstration of Spiral's ability for heterogeneous programming. I want to do more backends for different kinds of devices, and posting this on HN to gauge the interest in this kind of work. While x86 devices have a ton of good languages, new and niche hardware is likely to have poor language support and tooling, so I am hoping to fill that gap with Spiral. Whether you are a company that has some new kind of hardware or a user of it and you are fatigued of programming it in C, that is what I aim to alleviate. Going from a low level language like C to a high level one like Spiral would significantly boost your productivity.

The backend I am demoing here is for UPMEM, but now that I have it as a template, I could easily make similar backends for other kinds of devices assuming I have access to at least a simulator.
