 This repository provides an easy-to-use solution to run inference servers on [Slurm](https://slurm.schedmd.com/overview.html)-managed computing clusters using [vLLM](https://docs.vllm.ai/en/latest/). **All scripts in this repository runs natively on the Vector Institute cluster environment**. To adapt to other environments, update the environment variables in [`vec_inf/client/slurm_vars.py`](vec_inf/client/slurm_vars.py), and the model config for cached model weights in [`vec_inf/config/models.yaml`](vec_inf/config/models.yaml) accordingly.
