Figure 7-2 The xcxclus Utility Display Icon
The following describes the format of the node icons:
1. The node designator is on the upper left of the icon.
2. The left portion of the icon represents the Ethernet connection or connections.
In this illustration, two Ethernet connections are used. The data for eth0 is above the data
for eth1.
As many as 4 Ethernet connections can be displayed.
3. The center portion of the icon displays core usage data for each CPU core in the node.
As many as 4 CPU cores can be displayed.
4. The right portion of the icon displays memory statistics.
5. The arrows at the top of the icon represent Interconnect activity.
6. The arrows at the bottom of the icon represent file I/O activity.
NOTE: The values in the arrows are in terms of MB/s, not a percent of utilization, and
rounded to the nearest integer.
Pointing to the icon with the mouse pointer opens a balloon that displays the purpose of that
portion of the icon. This information is also represented in the status bar at the bottom of the
window.
The xcxclus utility can generate a data file. The data for each monitored node is updated each
second. The clusplot utility uses this data to plot graphs of various node performance statistics.
See “Using the xcxperf Utility to Display Node Performance” (page 77).
When you specify the -o option and a prefix, the xcxclus utility generates a data file for all
allocated nodes. The following example runs the xcxclus utility and stores the output in a file,
named test.xclus:
$ /opt/xtools/bin/xcxclus -o test
