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 Enterprise Linux 6.

OpenLAB Cluster

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

There are two types of nodes we have:

• 8 Sun Fire X2200 M2 nodes with Dual Operon (2.2ghz) Quad Core Processors (8 logical processors each), 8GB of ram and a local 750GB 7200RPM scratch disk. These will can be scheduled with the basic Torque queue dque.
  • openlab00.umiacs.umd.edu
  • openlab01.umiacs.umd.edu
  • openlab02.umiacs.umd.edu
  • openlab03.umiacs.umd.edu
  • openlab04.umiacs.umd.edu
  • openlab05.umiacs.umd.edu
  • openlab06.umiacs.umd.edu
  • openlab07.umiacs.umd.edu
• 2 nodes with Dual E5-2690 (8 logical processors each), 128GB of ram and 2 400GB local scratch disks. Additionally these each have two Tesla K20c GPUs available in each node. These nodes need to be scheduled with the Torque queue gpu.
  • openlab08.umiacs.umd.edu
