Processor Load Balance and Performance Charts
At the foot of the processor performance chart you find summary data for the entire
node, which for the most part are totals of the corresponding values for the CPUs. The
figure for the average processor busy percentage is simply the arithmetic average of the
values for the individual processors.
The tuning window is the amount that the percentage busy time for any processor can
deviate, either up or down, from the average value for the node without being considered
out of balance. The tuning window thus indicates the target utilization for the processor.
The tuning window decreases as the utilization level of the node goes up. At the
maximum recommended utilization level, the tuning window is only plus or minus 1
percent. For \NODEA, the relatively low utilization level of 36.2 percent results in a
relatively large tuning window value of plus or minus 8.0%.
