Nexus/QuICS
The Nexus cluster already has a large pool of compute resources made possible through college-level funding for UMIACS and CSD faculty. Details on common nodes already in the cluster (Tron partition) can be found here.
Please contact staff with any questions or concerns.
Submission Nodes
You can SSH to nexusquics.umiacs.umd.edu to log in to a submission node.
If you store something in a local filesystem directory (/tmp, /scratch0) on one of the two submission nodes, you will need to connect to that same submission node to access it later. The actual submission nodes are:
nexusquics00.umiacs.umd.edunexusquics01.umiacs.umd.edu
Compute Nodes
The compute nodes are named legacy## and quics00.
QoS
QuICS users have access to all of the standard job QoSes in the QuICS partition using the quics account.
The additional jobs QoSes for the QuICS partition specifically are:
highmem: Allows for significantly increased memory to be allocated.huge-long: Allows for longer jobs using higher overall resources.
Please note that the partition has a GrpTRES limit of 100% of the available cores/RAM on the partition-specific nodes in aggregate plus 50% of the available cores/RAM on legacy## nodes in aggregate, so your job may need to wait if all available cores/RAM (or GPUs) are in use.
Jobs
You will need to specify --partition=quics and --account=quics to be able to submit jobs to the QuICS partition.
Storage
QuICS users can request Nexus project allocations.
