Project description

pyslurmutils

SLURM utilities for Python.

Demo

Get an access token on rnice

export SLURM_TOKEN=$(scontrol token lifespan=3600)
export SLURM_URL=...
export SLURM_USER=...

Run any of the example scripts

python3 scripts/examples.py

Run the tests (CI or locally)

python3 -m pytest .

When SLURM_TOKEN, SLURM_URL or SLURM_USER is missing it will mock the SLURM clients.

Execute a python function on SLURM

Execute a function on SLURM with an API similar to python's concurrent.futures

from pyslurmutils.concurrent.futures import SlurmRestExecutor

with SlurmRestExecutor(
    url,
    user_name,
    token,
    log_directory=log_directory,  # for log files
    data_directory=data_directory,  # TCP when not provided
    pre_script="source /etc/profile\nmodule load ewoks",  # load environment
    python_cmd="python",
) as pool:

    future = pool.submit(sum, [1, 1])
    assert future.result() == 2
