Managing Batch Jobs
This page is under construction! We cannot guarantee completion or accuracy of information herein while in development.
Overview
It may be helpful to get information about queued, running, or past jobs. There are several functionalities within Slurm that can help with this process. Note that all of the following commands are contextual to the current cluster. To view commands on a different cluster, type the name of that cluster, and then run the command.
Queued & Running Jobs
To see jobs that are in the queue or currently running on the current cluster, use squeue --user $USER. Note that this command will not show jobs that have finished via completion, cancellation, or any other reason.
Previous Jobs
Users may want to review details of past jobs, or to study their performance to improve future jobs. The following commands may help:
