Figure 7-1 The xcxclus Utility Display
The icons show most node utilization statistics as a percentage of the total resource utilization.
For example, Figure 7-1 indicates that the CPU cores are almost fully utilized, at 94 per cent, and
95 per cent of available CPU time. These values are rounded to the nearest integer.
Selecting (that is, clicking on) an icon automatically invokes another utility, xcxperf, described
in “Using the xcxperf Utility to Display Node Performance” (page 77). It displays a graph of the
corresponding node's performance.
Figure 7-2 shows a node from Figure 7-1 with numeric designators for the individual portions.
