Node Types

On Pathfinder, there are two major types of nodes you will encounter: Login and Compute. While these are similar in terms of hardware, they differ considerably in their intended use.

Node Type Description
Login When you connect to Baseline, you’re placed on a login node. This is the place to write/edit/compile your code, manage data, submit jobs, etc. You should never launch parallel jobs from a login node nor should you run threaded jobs on a login node. Login nodes are shared resources that are in use by many users simultaneously.
Compute Most of the nodes on Baseline are compute nodes. These are where your parallel job executes. They’re accessed via the srun command.
