JAMS Reference Manual

1.13 Node Groups

Node Groups are groups of remote nodes which can be treated as a single node. JAMS Node and Node Group Definitions are used to validate the node name entered in a remote job dependency definition. A Node Group is a list of remote nodes which can be referred to by its group name as though it were a node.

In many environments, there is a central VAXcluster with many remote, smaller processing sites. If you wanted to make a Job on the central VAXcluster depend upon the completion of another Job at each of the remote sites, you could add a Job Dependency to the Job on the central VAXcluster for each of the remote sites or create a Node Group which includes all of the remote sites and then create only one Job Dependency which refers to the Node Group.

Group Name

This is the name of the Node Group. You can use this name anywhere JAMS expects a remote node name.
