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

Loring ( provided x nodes )

...

• nodes might be used for testing CAC setup)

...

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

• Song Lin (
