Logical partitioning of processors
The method of logically splitting the physical processor is referred to as the scheduling
mode. This mode allows you to specify dedicated or shared. They are called the dedicated
mode and shared mode. Different features of each mode are shown in the table below.

Explanation
Dedicated
mode
The logical processor on a LPAR exclusively uses the corresponding
physical processor.
For each LPAR, it is possible to specify the number of logical
processors assigned. (However, it is not possible to specify more than
the number of physical processors available.)
It is also possible to specify the physical processor number that a logical
processor uses.
If the physical processor number is not specified, LPAR manager
determines to assign the number to be used when the LPAR is
activated.
Since there is no overhead for switching the physical processors
between the logical processors, the LPAR performs faster.
Shared mode Physical processors are time-shared among the logical processors
defined in the LPAR for which the shared mode is specified.
The number of logical processors to be used in the shared mode can be
set for each LPAR. (It is possible to specify more than the number of
physical processors available, but operations might slow down to an
extreme level.).
The utilization rate of the physical processors can be set dynamically for
each LPAR, allowing flexible use of physical processor resources.
The scheduling mode for processors is set per LPAR, so it is not possible to specify a
different scheduling mode for each individual logical processor within a single LPAR.
