| = Slurm Controller Daemon (slurmctld) Setup on slurm-master (LXC) =
| |
|
| |
| '''Note:'''
| |
| To access the shell of any Linux container (e.g., slurm-master), run the following command from the infra node:
| |
| <pre> lxc exec <container-name> bash </pre>
| |
|
| |
| Example:
| |
| <pre> lxc exec slurm-master bash </pre>
| |
|
| |
| == 1. Install Required Packages ==
| |
|
| |
| Run the following command inside the slurm-master container:
| |
| <pre> sudo apt install munge slurmctld </pre>
| |
|
| |
| This installs:
| |
|
| |
| * munge – for authentication between Slurm components.
| |
|
| |
| * slurmctld – the Slurm controller daemon.

| = Sample slurm.conf Configuration =
| |
|
| |
| '''Note:'''
| |
| The following is a sample Slurm controller configuration file (slurm.conf). You can use this as a reference template for setting up your cluster.
| |
|
| |
| : Make sure to modify the node names, IP addresses, memory, CPU configuration, and other values according to your actual cluster setup.
| |
|
| |
| == Create slurm.conf File ==
| |
|
| |
| Create the slurm.conf file at the following location on all nodes:
| |
| <pre>
| |
| /etc/slurm/slurm.conf
| |
| </pre>
| |
|
| |
| Paste the below content int
| |
|
| |
| <pre>
| |
| # **Note:** This file needs to have identical contents on all nodes of
| |
| # the cluster. See the `slurm.conf` man page for more information.
| |
| #
| |
|
| |
| # Unique name for identifying this cluster entries in the DB
