Manage your cluster

Administer a Charmed HPC cluster after initial deployment, from routine compute node operations to cluster-wide changes that require a maintenance window.

Manage compute nodes and partitions

Adjust the configuration and state of individual compute nodes, and change partition capacity as demand on your cluster changes.

• Apply custom configuration to specific compute nodes

• Modify the default state and reason of new compute nodes

• Modify the state of compute nodes

• Scale partitions

Maintain security

Replace the keys that secure internal cluster communication and REST API access.

• Rotate the Slurm authentication key

• Rotate the JWT authentication key

Enable high-availability

• Migrate Slurm controller to high availability
