Configure Slurm

A YAML cluster configuration file for a Slurm resource manager on an HPC cluster looks like:

# /etc/ood/config/clusters.d/my_cluster.yml
---
v2:
  metadata:
    title: "My Cluster"
  login:
    host: "my_cluster.my_center.edu"
  job:
    adapter: "slurm"
    cluster: "my_cluster"
    bin: "/path/to/slurm/bin"
    conf: "/path/to/slurm.conf"
    # bin_overrides:
      # sbatch: "/usr/local/bin/sbatch"
      # squeue: ""
      # scontrol: ""
      # scancel: ""

with the following configuration options:

adapter

This is set to slurm.

cluster

The Slurm cluster name. Optional, passed to SLURM as -M <cluster>

bin

The path to the Slurm client installation binaries.

conf

The path to the Slurm configuration file for this cluster. Optional

bin_overrides

Replacements/wrappers for Slurm’s job submission and control clients. Optional

Supports the following clients:

• sbatch

• squeue

• scontrol

• scancel

Note

If you do not have a multi-cluster Slurm setup you can remove the cluster: "my_cluster" line from the above configuration file.

Tip

When installing Slurm ensure that all nodes on your cluster including the node running the Open OnDemand server have the same MUNGE key installed. Read the Slurm Quick Start Administrator Guide for more information on installing and configuring Slurm itself.
