Summary

Hydra is a framework for configuring complex applications elegantly. It has become popular among researchers and practitioners since its initial release, and now users can scale and launch jobs to the cloud through the new Hydra Ray Launcher. The Hydra Ray Launcher uses Ray, a simple yet powerful Python library for parallel and distributed programming, to enable easy configuration and launching of applications on Ray in three different ways: starting or connecting to an AWS EC2 cluster, connecting to an existing long-running Ray cluster, or starting a local Ray cluster. Users can launch applications by setting the hydra/launcher parameter, configuring clusters with yaml files, and running scripts with command line overrides. The Hydra Ray Launcher is built on top of Ray's cluster launcher CLI and provides a simple way to run applications on AWS EC2 Ray Clusters.
