Running Interactive Jobs on Roar Collab

Interactive jobs allow a user to use compute resources while running commands and viewing output in real-time.

Note: To prevent performance issues for all users, intensive tasks such as code compilation and workflow troubleshooting should be done within interactive jobs.

To start an interactive job, use the “salloc” command. Using Slurm directives, job resource requirements can be customized. For example, to start a job over 4 cores and lasting 3 hours enter:

$ salloc -N 1 -n 4 --mem-per-cpu=1024 -t 3:00:00
