Slurm Installation

Omnivector Solutions provides a repository for Slurm packages, for both CentOS 7 and Ubuntu 20.04. This is used to ensure the charms install a supported and stable Slurm version. The currently supported Slurm version is 20.11.8 on CentOS 7 and 20.11.7 on Ubuntu Focal.

Omnivector Slurm Distribution allows one to use a custom repository URL to install Slurm from. This is specially useful to allow using a local mirror/cache of packages to speedup installation. This also allows one to specify different repositories for testing new Slurm versions, or upgrading only specific charms.

All of the Slurm charms have a configuration option custom-slurm-repo to specify a different repository URL.

Note

The configuration custom-slurm-repo must be set before deploying the units. Changing this value after deploying the units will not have any effects on the Slurm version.

Changing the repository

To use a custom package repository, set the value of custom-slurm-repo in your bundle file for all slurm-charms, before deploying the system. For Ubuntu units, the URL must be a valid PPA URL. For CentOS 7 units, the URL can contain a $basearch variable. For example:

applications:
  slurmd-centos:
    charm: slurmd
    num_units: 1
    series: centos7
    custom-slurm-repo: https://omnivector-solutions.github.io/repo/centos7/stable/$basearch
  slurmd-ubuntu:
    charm: slurmd
    num_units: 1
    series: focal
    custom-slurm-repo: ppa:omnivector/osd
  ...

Another possibility is to supply the repository URL in the command line when deploying the units:

$ juju deploy slurmd --series centos7 --config custom-slurm-repo='https://omnivector-solutions.github.io/repo/centos7/stable/$basearch'

Note

It is the responsibility of the system administrator to ensure that all Slurm components are running a compatible Slurm version, when using a custom repository. Omnivector Solutions' repository hosts packages that guarantee the compatibility of all components.
