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 )
