hydra-submitit-extension 0.0.5

A more flexible hydra submitit launcher

hydra_submitit_extension

A more flexible Hydra Submitit Launcher plugin

This launcher is a extension of Submiti Launcher Plugin.

Features:

• Iterative scheduling of jobs:
  • Max Number for Active and Pending Jobs
  • Automatically Schedule Jobs and Wait depending on Limits

Drawbacks:

• Single Jobs are submitted instead of Job arrays
• Hydra must be active to schedule jobs
• No Naming Scheme for Slurm jobs. This makes manual canceling difficult

Installation

pip install hydra-submitit-extension
