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
The Lighthouse cluster supports researchers with grants that require the purchase of computing hardware. Lighthouse allows researchers to place their own hardware within the ARC HPC Slurm environment. It utilizes Slurm as its workload manager, enabling users to work interactively or submit batch jobs.To access this cluster, you must have a login and a Slurm account to submit jobs. There are three ways to interact with this cluster:
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).
