CEWIT Cluster Information (Using Rocks 4.2.1)

Latest Updates

  • You can view the current status of the cluster using the following steps:
    • First log into the host 'cewit.cs.sunysb.edu' using ssh.
    • Start firefox. Go to page http://localhost/wordpress/
    • Click on Cluster Status. Click on 'Physical View' for rackwise list of machines.
  • 156 64bit Compute/PVFS/NFS nodes are operational on Rocks (Racks #2, 3, 4, Racks #6, 7, 8, and Racks #9,10, 11).
  • One 64bit HP Compute node is also operational on Rack 0 (Infrastructure Rack - compute-0-4). The 64bit nodes currently can access 32GB of main memory.

CEWIT Clusters

The CEWIT cluster machine comprises of 20 racks, nearly 300 node, 450 CPU systems. Some racks are dedicated for ongoing CEWIT research in individual labs. These labs are

  • Applied Algorithms Lab
  • Media Networks Lab
  • File Systems and Storage Lab
  • Secure Systems Lab

Rest of the racks are available for CEWIT research for the rest of department. The system staff has been researching possible implementations of the CEWIT clusters administration and management softwares. Specifically, the group looked at OSCAR, ROCKS and a commercial package called MOAB. Current thinking has favored ROCKS.

An initial Cluster installation has been configured using ROCKS for the infrastructure rack (Rack #0). The original documentation for ROCKS software version 4.2.1, is given here. This installation has multiple 'compute' nodes in addition to a file server for home directories. Very recently, we also included 'pvfs2' type of nodes to share storage on various nodes. The user database will be integrated with the CS department Sun machines.

This website will provide updates of the status of the CEWIT configurations and also provide a location to get any client software or user information regarding accessing and using the cluster(s).
