New page

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 [[Nexus/Tron | here]].

Please [[HelpDesk | contact staff]] with any questions or concerns.

= Submission Nodes =
You can [[SSH]] to <code>nexusquics.umiacs.umd.edu</code> 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:
* <code>nexusquics00.umiacs.umd.edu</code>
* <code>nexusquics01.umiacs.umd.edu</code>

= Compute Nodes =
The compute nodes are named <code>legacy##</code> and <code>quics00</code>.

= QoS =
QuICS users have access to all of the [[Nexus#Quality_of_Service_.28QoS.29 | standard job QoSes]] in the QuICS partition using the <code>quics</code> account.

The additional jobs QoSes for the QuICS partition specifically are:
* <code>highmem</code>: Allows for significantly increased memory to be allocated.
* <code>huge-long</code>: Allows for longer jobs using higher overall resources.

Please note that the partition has a <code>GrpTRES</code> 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 <code>--partition=quics</code> and <code>--account=quics</code> to be able to submit jobs to the QuICS partition.

= Storage =
QuICS users can request [[Nexus#Project_Allocations | Nexus project allocations]].
