ClusterFsck Reincarnated

Due to a friends' help, clusterfsck is back. Newer, faster, stronger, and so forth.

Machine Info

  • Head node is P3/504, 512MB, dual fast ethernet (internal / external)
  • Compute nodes are all P2/233, 256MB, 4G disk, fast ethernet
  • Cluster switch is a D-Link 5-port, 128k per buffer, non-blocking.
  • Net connection is via Earthlink ADSL, 1.5M/384k
  • All machines have Fibre Channel cards in them, so we can experiment with GFS once there's time.

    Software Info

    Currently, the cluster uses the Beowulf system, based around RH6.2.

    Performance Results

    Linpack (MPI) gives about half a gigaflop. Just like the original, we're a fraction of a current machine:
