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.
Great Lakes
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?
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. For more Great Lakes hardware specifications, see the Configuration page.Partitions:
A per-principal investigator (PI) or per-project root account contains one or more Slurm subaccounts, each with their own users, limits, and shortcode(s). The entire root account has limits for overall cluster and /scratch usage in addition to any limits put on the sub-accounts.
Slurm is a combined batch scheduler, billing, and resource manager that uses slurm accounts to allow users with a login to the High Performance Computing clusters to run their jobs for a fee. For many researchers this fee is paid for by the University of Michigan Research Computing Package account.
