3. Add Cluster Configuration Files

(Optional, but recommended)

The following apps do not require a cluster configuration file:

The following apps do require a cluster configuration file:

  1. Create the default directory that the cluster configuration files reside under:

    $ sudo mkdir -p /etc/ood/config/clusters.d

  2. Create a cluster YAML configuration file for each HPC cluster you want to provide access to. They must have the *.yml extension.

    Note

    It is best to name the file after the HPC cluster it is defining. For example, we added the cluster configuration file /etc/ood/config/clusters.d/oakley.yml for the Oakley cluster here at OSC.

    The simplest cluster configuration file for an HPC cluster with only a login node and no resource manager looks like:

    # /etc/ood/config/clusters.d/my_cluster.yml
---
v2:
  metadata:
    title: "My Cluster"
  login:
    host: "my_cluster.my_center.edu"

    Where host is the SSH server host for the given cluster.

    In production you will also want to add a resource manager. That is because the Active Jobs App and the Job Composer App won’t be able to list or submit jobs without a defined resource manager.
