Node Characteristics
This subsection of the report (Example 3-1) gives general performance figures for the node
GPA has analyzed. For each line item in this subsection, the report shows a measured
value and, where it applies, the maximum value the GPA model expects.

The line items are:
(1)
CPU TYPE: The type of CPU that is being measured.
(2)
CPU COUNT: The total number of processors in the node. The figures in
the illustration show that the node sampled has 4 CPUs and that GPA
can handle up to 16.
(3)
TOTAL MEMORY: The total number of megabytes of memory in the
node. The node illustrated has a total of 32 megabytes of memory.
(4)
VOLUME COUNT: The total number of disk volumes in the node. The
node has 9 volumes.
(5)
STATIC PCBS: The number of static process control blocks on the
node. This figure tells you how many steady-state processes were
active on all CPUs during the measurement period analyzed by GPA.
