Processor Load Balance and Performance Charts
From Example 4-13 you can see that on \NODEB, the least utilized processor, CPU 3, is
out of balance. Since the percentage busy times for the other three processors fall within
the target utilization for the system (discussed later in this section), GPA considers these
processors to be in balance.
The next chart in this section of the report identifies each of the processors on the node
with respect to number and type. In addition, the chart shows explicitly how the values
for a number of performance parameters are distributed among each of the processors. It
thus indicates which are the problem processors on the node. Here you can also see
more precisely than in the Processor Load Balance Chart what the percentage busy time
is for each processor.
The Processor Performance Chart also shows how many disk processes (DISK PRIME)
are primaried on each CPU. Notice in our examples how unevenly the primary disk
processes are distributed among the CPUs, which accounts partly for the load imbalance
condition on these nodes. (One GPA function is to determine how such an imbalance
