Process Move Recommendations

In the section of the report shown in Examples 4-24 through 4-26, GPA lists the processes

that you might move or switch to other CPUs to improve the load balance and memory
utilization on the node.

Report Considerations

No report will be produced if no candidates are found. There are no user-supplied runtime

options to initiate these reports; they are STANDARD reports.

The three standard reports are the following:

Process Moves for Memory Imbalance

Process Primary Switches for CPU Imbalance

Process Moves for CPU Imbalance

In the case of \NODEA, for example, GPA has tried to free up some severely needed

memory in CPU 0 by recommending that two processes be moved as shown in
Example 4-24.

Example 4-24. Process Move Recommendations for \NODEA

To correct a processor utilization imbalance on \NODEB (Example 4-25), GPA has

recommended that ten processes running on CPU 1 be moved and distributed as
shown among the other three processors in the system.
