and monitor the nodes in
your job allocation
“Specifying Nodes for xclus
or xcxclus” (page 79)
Use one of the following commands to start the utility
and specify the nodes you want to monitor:
• xclus|xcxclus -nodes
node_specification...
• xclus|xcxclus -cluster cluster_filename
Where cluster_filename contains the names of
the nodes or systems you want to monitor
Start xclus or xcxclus
and monitor a subset of
the nodes in your job
allocation
“Specifying Nodes for xclus
or xcxclus” (page 79)
Specify the nodes or systems you want to monitor as
described previously and specify the option
-unrestricted-nodes. You must have superuser
capabilities to use this option with xcxclus.
Start xclus or xcxclus
and monitor nodes
outside your job
allocation
“Specifying Nodes for xclus
or xcxclus” (page 79)
You must specify the nodes or systems you want to
monitor. Use one of the following commands:
• xclus -nodes node_specification...
• xclus -cluster cluster_filename
Where cluster_filename contains the names of
the nodes or systems you want to monitor
• xclus
Where the file named cluster in the current
working directory contains the names of the nodes
or systems you want to monitor
