Process Move Recommendations

This section of the report (Example 3-14) contains recommendations, based on the GPA

analysis of the node, for improving the performance of the system. It tells what

processes could be moved to other CPUs on the node to achieve a more balanced load

distribution and better utilization of existing memory. You implement the moves that are

appropriate for your particular situation.

As Example 3-14

shows, the report gives: (1) the identification number of each memory-

short or overutilized CPU and (2) the number of pages of memory shortage or, in the

case of an overutilized CPU, the percentage of overutilization (before any process moves

but after the GPA primary path moves for the CPU).

For each processor, the report lists:

(1) DISK PINS: The number of disk subprocesses configured for the volume at the

last SYSGEN.

(2) Net Msg Rate: A measure of the workload handled by each subprocess. (See

the Glossary

for a more exact definition of “net messages.”) Up to eight PINs

can be configured for each logical disk volume.

(3) NET CHNG: The recommended change to the number of disk subprocesses for

the logical volume. This change requires a SYSGEN.

(4) NEW PINS: The new total number of PINS after the net change is applied. This

analysis considers CPU cycle availability, PCB availability, memory availability,

and request traffic. Based on all of these factors, it recommends adding or

deleting disk subprocesses.

(1) CPU: The identification number of each memory-short or overutilized CPU.

(2) SHORT MEMORY BY: The number of pages of memory shortage or, in the

case of an overutilized CPU, the percentage of overutilization (before any

process moves but after the GPA primary path moves for the CPU).

(3) The process identification (CPU number, PIN, and process name).

(4) The program file (volume, subvolume, and filename).

(5) The CPU to which the process is to be moved.
