The following nodes are restricted to specific groups controlled by the purchasers of the nodes. Requests for access to these nodes will need to be confirmed by the owner of the node before access will be granted. We additionally have a node called burst1 used for lab and training sessions, and as a burst node for extending the capacity of the cluster outside term-time.
