HP XC System Software Release Notes for Version 3.1

The xcxclus utility is a graphic utility that enables you to monitor a number of nodes
simultaneously. The utility displays an array of icons. Each icon represents a node in the job
allocation and provides the following information:
• Ethernet activity
• Core utilization
• Memory utilization
• Interconnect I/O activity (for InfiniBand and Gigabit Ethernet interconnects only)
• Disk I/O activity (for nodes with attached disks)
When you invoke the xcxclus utility from the command line, it determines which nodes your
current jobs are using and opens a window that displays utilization metrics for those nodes. If
you are not running any jobs, the xcxclus utility terminates.
The xcxperf utility provides a graphic display of node performance for a variety of metrics.
You can invoke the xcxperf utility either by entering it on the command line or by selecting a
node icon in the xcxclus display. The xcxperf utility displays a dynamic graph showing the
performance metrics for the node.
User information for both utilities is documented in the HP XC System Software User's Guide.
