Specific directions on accessing and using the Collum-Loring-Abruna-Widom ( CLAW ) cluster

Nodes are not shared between groups, by default

By default, each group can only use their group's compute nodes.

  • This is enforced technically.
    • Command-line: Applies to all groups
    • WebMO (GUI access): Currently applies only to the Collum group (as of 11/4/16).
      • Q: Can WebMO be used by any other group to access only their group's nodes?
  • Faculty members may create social agreements to permit cross-group access of nodes.
    • This increases group member's responsibility not to abuse any nodes they are guests to.
    • Chemistry IT staff are hopeful that the default restrictions can be modified to enable desired sharing.

Groups using this cluster

Groups having invested hardware into the cluster

  • Collum contributing 8 compute nodes. Maybe 1 more (former head node).
  • Loring contributing 5 compute nodes. Oldest nodes on the cluster.
  • Widom contributing 8 computer nodes. All 8 nodes have 12 TB hard drives (2*6T) for each node paid for by Collum.
    • Extra hard drive space of value only to the Collum group.
  • Widom contributing the current head node.

Future addition, hopefully:

  • Abruna (n nodes as some of his 10 nodes might be used for testing CAC setup)

Guest groups using cluster under the auspices of a cluster sponsoring group(s):

  • Song Lin ( 0 nodes )
