OpenLAB
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.
- opensub00.umiacs.umd.edu
- opensub01.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.
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
- 2 nodes with 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 these each have two Tesla K20c GPUs available in each node and one node has a M40. These nodes need 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
