HPC Cluster

This is the starting point for deploying an HPC Cluster with juju.

Prerequisites

Juju

Install snap:

apt install snapd

Install juju:

snap install juju --channel=3.0/stable

Set up juju (for lxd, "localhost-localhost"):

juju bootstrap
juju add-model default

Charms

• https://github.com/canonical/hpc-node-operators
• https://github.com/canonical/hpc-package-operators
• https://github.com/canonical/openldap-operators

To Monitor

Set up monitor (in separate terminal window):

juju status --watch 5s --relations

Basic Cluster

Note: Initial version of hpc-cluster.yaml is set up to pull local charms from the current directory. This will be updated once the charms are in the charmhub store.

Deploy

Note:

The required charms must be available. At the moment (2022-12-12), they should be in the same directory as the hpc-cluster.yaml file.

Deploy the cluster:

juju deploy ./hpc-cluster.yaml

Scaling

Increase head (from 1 to 2):

juju add-unit -n 1

Increase interactive (from 1 to 4):

juju add-unit interactive -n 3

Increase compute (from 1 to 10):

juju add-unit compute -n 9
