The Nexus is the combined scheduler of resources in UMIACS. Many of our existing computational clusters that are discrete will be folding into this scheduler. The resource manager for this is SLURM and resources will be arranged into partitions of resources where users will be able to schedule computational jobs. Users will be arranged into a number of Slurm accounts based on faculty, lab or center investments.

Accounts

All accounts in UMIACS are required to be sponsored and can be requested in our Requests application. Each faculty will be required to have an account to sponsor their students and collaborators. When a user fills out the form they will list their Principal Investigator/Sponsor. Faculty accounts should list the UMIACS Director of Computing (currently derek) while all other users should list their UMIACS faculty member for this sponsorship.

The submission nodes for the Nexus computational resources are determined by department, center or lab affiliation. Users can log into the UMIACS Directory application and select their Computational Resources (CR). They will find a CR that has the prefix nexus and select it to list their available login nodes.

Note - UMIACS requires multi-factor authentication through our Duo instance. This is completely discrete from both UMD and/or CSD Duo instances and users will need to enroll device(s) to access resources in UMIACS. Users will be prompted when they log into the Directory application the first time.

Access

Once users have identified their submission nodes they will be able to SSH into them.

Partitions

  • Nexus/Tron - This currently the pool of resources available to all UMIACS and CSD faculty and graduate students. It will provide access for undergraduate and graduate teaching resources.
