Physical Description

• Nodes

  There are twelve nodes, in total. One node is a submit node, where you develop, compile, and submit your jobs to a job scheduler. This is the node that you will access directly. The other eleven nodes are the compute nodes, where your jobs will actually run. Every node is configured as follows:

  • Two 3.0 GHz Xeon EM64 processors
  • 8GB RAM
  • 2GB of transitory storage in /tmp
  • 60GB of transitory storage in /scratch1
  • 160GB of transitory storage in /scratch2

• Network

  Every node has a connection to a commodity gigabit ethernet network for IP communication. In general, this should only be used as a control connection. For message passing, the compute nodes have a connection to an Infiniband network. You can access the interconnect natively using MPI or you can use IP over infinband through the vnodeNN-ib interface.
