The HP Job
Performance Analyzer tool suite delivers the xcxclus and xcxperf monitoring utilities. These utilities
provide real-time, interactive, system-wide monitoring of a user application
and display resource utilization on all cluster components (CPUs,
memory, I/O, and interconnect) simultaneously while an application
is running.
The HP Job Performance Analyzer software is optional
and is not installed by default with the HP XC System Software. The HP XC System Software Administration Guide describes
how to install this optional software from the HP XC DVD.
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:
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.
