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. |
