Installation

The Hydra Slurm Rich Launcher can be installed via pip:

pip install hydra-slurm-rich-launcher --upgrade

Alternative installation methods

Locally

```
git clone [email protected]:creinders/hydra-slurm-rich-launcher.git
cd hydra-slurm-rich-launcher
poetry install
```

Quick Start

Define your configuration in config.yaml:

defaults:
  - override hydra/launcher: slurm_rich
hydra:
  launcher:
    partition: <SLURM_PARTITION>

task: 1

Implement your Hydra app in my_app.py:

import hydra

@hydra.main(config_path=".", config_name="config", version_base="1.3")
def my_app(cfg) -> None:
    print(f"Task: {cfg.task}")

if __name__ == "__main__":
    my_app()

Starting the app with task=1,2,4 will launch three jobs with different configurations:

python my_app.py task=1,2,4 --multirun

Please see the Hydra documentation for details regarding the configuration and multi-run.

Scalability

Lots of run? No problem! Hydra Slurm Rich Launcher smartly organizes all of your runs.

Restarts

Easily monitor the status of your jobs and swiftly restart any failed runs.
