Features

slurmutils is a collection of various utilities and APIs to make it easier for you and your friends to interface with the Slurm workload manager, especially if you are orchestrating deployments of new and current Slurm clusters. Gone are the days of seething over incomplete Jinja2 templates. Current utilities and APIs shipped in the slurmutils package include:

from slurmutils.editors import ...

  • slurmconfig: An editor slurm.conf and Include files.
  • slurmdbdconfig: An editor for slurmdbd.conf files.

Installation

Option 1: Install from PyPI

$ python3 -m pip install slurmutils

We use the Poetry packaging and dependency manager to manage this project. It must be installed on your system if installing slurmutils from source.

$ git clone https://github.com/canonical/slurmutils.git
$ cd slurmutils
$ poetry install

Usage

Editors

slurmconfig

This module provides an API for editing both slurm.conf and Include files, and can create new configuration files if they do not exist. Here's some common Slurm lifecycle management operators you can perform using this editor:

Edit a pre-existing slurm.conf configuration file
from slurmutils.editors import slurmconfig

# Open, edit, and save the slurm.conf file located at _/etc/slurm/slurm.conf_.
with slurmconfig.edit("/etc/slurm/slurm.conf") as config:
    del config.inactive_limit
    config.max_job_count = 20000
    config.proctrack_type = "proctrack/linuxproc"
Add a new node to the slurm.conf file
from slurmutils.editors import slurmconfig
from slurmutils.models import Node

with slurmconfig.edit("/etc/slurm/slurm.conf") as config:
    node = Node(
        NodeName="batch-[0-25]", 
        NodeAddr="12.34.56.78", 
        CPUs=1, 
        RealMemory=1000, 
        TmpDisk=10000,
    )
    config.nodes[node.node_name] = node

slurmdbdconfig

This module provides and API for editing slurmdbd.conf files, and can create new slurmdbd.conf files if they do not exist. Here's some operations you can perform on the slurmdbd.conf file using this editor:

Edit a pre-existing slurmdbd.conf configuration file
from slurmutils.editors import slurmdbdconfig

with slurmdbdconfig.edit("/etc/slurm/slurmdbd.conf") as config:
    config.archive_usage = "yes"
    config.log_file = "/var/spool/slurmdbd.log"
    config.debug_flags = ["DB_EVENT", "DB_JOB", "DB_USAGE"]
    del config.auth_alt_types
    del config.auth_alt_parameters
