Welcome to using the cluster from the command line where you can do different things than using Open On Demand.
If you are using data types that may need special considerations be sure to visit the Safe Computing Data Guide
Why use the command line?
Lighthouse
NOTICE: Multi-factor authentication (MFA) with Duo is still required to access the cluster via Open OnDemand. DO NOT delete your Duo application if you wish to continue to use SSH or the terminal in Open OnDemand.If you are new to HPC, please ensure you have a device enrolled in Duo for MFA. Follow the steps in this knowledge article to enroll your device.
Open OnDemand is a way for users to run interactive jobs on Great Lakes, Armis2 and Lighthouse. Start computing immediately. A simple interface makes Open OnDemand easy to learn and use. This includes:
Partition PoliciesSlurm partitions represent collections of nodes for a computational purpose, and are equivalent to Torque queues.Each PI’s standard compute nodes are identified by the PI’s uniqname and have a maximum job walltime of 14 days (can be increased up to 4 weeks at the PI’s request; ARC reserves the right to interrupt jobs for maintenance purposes).
