Yeah, I’ve had to rewrite continuous batching and other scheduling logic. That and multi-GPU inference have been the hardest things to build.
I’ll need to get paged attention working as well, but I think I can launch without it.
We used candle[0], which uses cudarc and the metal crate under the hood. That means we run on nvidia hardware in production and can test locally on macbooks with smaller models.
I would certainly like to use non nvidia hardware but at this point it's not a priority. The subset of tensor operations needed to run the forward pass of LLMs isn't as large as you'd think though.
Just trying to stay focused on launching first (https://docs.mixlayer.com) and keeping early customers happy, but would love to open source some of this work.
It'd probably be a separate crate from candle. If you haven't checked it out yet, mistral.rs implements some of these things (https://github.com/EricLBuehler/mistral.rs). Eric hasn't done multi-GPU inference yet, but I know it's on his roadmap. Not sure if it helped, but I shared an early version of my llama 3.1 implementation with him.
Hey, mixlayer is really cool.
I also have a Rust LLM inference project. The overlap is very high between what mixlayer is doing and what my project is doing. It's actually crazy how we basically have the same features. [1] Right now I'm still using llama.cpp on the backend, but eventually want to move to candle via mistral.rs.
Are you aiming for Nvidia hardware with rust-cuda, or looking to integrate with non-Nvidia hardware?
