prm_stat - report status of a PRM system
prm_stat [ -u ] smhost
prm_stat queries the system manager running on host smhost
and displays the status of nodes managed by this system
manager. Also printed is the list of jobs (if any) that
are currently using one or more nodes.
-u Update status. By default, the system manager supplies
stored status information. Specifying the -u option
forces the system manager to update its status informa-
tion by querying each node it manages.
