The Cluster in Geological Sciences

Micah is a cluster running ROCKS 5.4.3 and consisting of

  • Master Node: - Opteron 2214, 2.2GHz socket-F dual core processor with 8 Gb of memory
  • Compute Nodes: - 18 nodes, each with 2 Opteron 2214, 2.2GHz socket-F dual core processors. Each of the 18 nodes has 8 Gb of memory.
  • Two Storage Nodes: Intel dual-core Xeon processor 5140 2.4 GHz with 8 Gb of memory
  • RAID System: Each Storage node has a RAID system with 6.8 Tb of available storage area

Connections between the nodes are via Infiniband and gigabit ethernet.

For current Information about the cluster

Run "rocks list host"
