cluv

cluv — sync UV-based Python projects across HPC clusters.

Status

In early development. Commands are functional, but expect bugs or missing features.

Requirements

Python >= 3.13
UV
SSH access configured for each cluster in ~/.ssh/config
A GitHub repository with your project

Installation

To add cluv to your project, use uv add or pip install:

uv add cluster-uv

To also include the Cluv Hydra launcher:

uv add cluster-uv[hydra]

Install as a command-line tool in an isolated environment:

uv tool install cluster-uv

If you want the bleeding edge version from GitHub, use:

uv add git+https://github.com/mila-iqia/cluv

Then you can run cluv directly as a command:

cluv init
cluv login mila
cluv sync mila
cluv submit mila job.sh

Documentation

Cluv is documented at https://mila-iqia.github.io/cluv/.
Command line help : Use cluv --help or cluv <command> --help.
Examples : See the examples folder for sample projects using cluv. Each example includes a README with instructions specific to that project.

Quick Start

Initialize your project with:
```
cluv init
```
Establish SSH connections to all configured clusters:
```
cluv login
```
Sync your project to all clusters and run uv sync on each:
```
cluv sync
```

Configuration

Add a [tool.cluv] section to the pyproject.toml of your project to manage the behavior of the tool. The command cluv init will add a default config if it doesn't already exists in the .toml.

See the config at the project root for an example, or refer to the docs.
