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.

Exceptions so far: Groups sharing nodes

Widom's nodes are available to the Collum group.

Collum group paid to add hard drives to all 7 of Widom's compute nodes. 12TB (= 6TB * 2) hard drive space now available on each of Widom's nodes.
At the time of this writing, the Collum group had no nodes in the cluster.
Recently all Widom nodes were used by Widom researcher. For now, that researcher can saturate only 6 of the 7 nodes.

Widom and Loring share each other's nodes. To clarify:
