Basic Slurm Commands#
On a personal computer, you typically launch an application by double-clicking a desktop icon or entering its name in a terminal. However, performing the same action on a cluster’s login node will execute the application locally on that login node, failing to utilize the cluster’s computational power.
Important
Login nodes have limited resources and are shared by all users. Running resource-intensive applications on a login node should be avoided at all costs, as it can degrade system performance for everyone.
To leverage the massive computational capacity of the cluster and run applications in parallel, you must submit your work through Slurm’s command-line interface (CLI). While Slurm is highly sophisticated, daily usage is straightforward; you only need a handful of core commands to be effective:
