Processor Group
You can restrict the use of physical processors for a group of LPARs by
forming a group of physical processors with one processor at the least. Any
number can be defined as a number of a physical processor group. A
processor with no processor number defined belongs to the processor group
"0". A processor group number can be specified by the core.
Overview
A function which defines a processor core as a group and restricts the range
of a shared processor to being in a group. It is possible to restrict in a group
with effect of load-fluctuating by above mentioned. It is possible to define
group by every user section and charge to an allocated processor
performance.

Change Group Assignment of Processor
Performance of processor group can be changed by changing group
assignment of processors. Definition of processor which changed group
assignment can change from shared mode to dedicated mode. Changing
group assignment of processor number 2 is shown below.
