The OpenLAB computing facility is a collection of initial nodes that all our users can use for their basic computer needs. They are backed by our NFShomes home directories. We currently run Red Hat Enterprise Linux 7.

Remote Login Nodes

Please connect to openlab.umiacs.umd.edu as it will connect you one of the two following remote login nodes. These are available via SSH.

  • opensub02.umiacs.umd.edu
  • opensub03.umiacs.umd.edu

The RSA SSH fingerprint for "openlab.umiacs.umd.edu" and all these specific hosts can be verified through the SSH Host Key Fingerprints page on the UMIACS Intranet.

We also have a RHEL8 login node, openrhel8.umiacs.umd.edu, that you can connect to. Please note that it cannot submit to the OpenLAB cluster as of right now. This node is intended to provide a place where you can validate / recompile your software before we eventually begin upgrading our compute resources to RHEL8.

OpenLAB Cluster

These nodes are not explicitly available to login to. They can either be scheduled from the submit/remote login nodes via SLURM.

Notes

  • One node (openlab08) has Dual E5-2690 @ 2.90GHz (8 logical processors each), 128GB of RAM, L1 cache: 512kB, L2 cache: 1024kB, L3 cache: 2042kB, and 2 400GB local scratch disks. Additionally, it has two Tesla K20c GPUs and one Tesla M40 GPU available. It needs to be scheduled with the SLURM partition gpu. To learn how to request GPUs in SLURM please make sure to read the section in the SLURM documentation on requesting GPUs.
