You can assign a specific amount of the processing capacity in a shared processor pool to each logical partition that uses shared processors.
Shared processors are physical processors whose processing capacity is shared among multiple logical partitions. By default, all physical processors that are not dedicated to specific logical partitions are grouped together in a shared processor pool. This task allows you to view information about your shared processor pool and to make changes to that pool.
Detailed information about configuring shared processor pools is available. For more information, see Configuring shared processor pools using the HMC version 7 release 3.2.0, or later.
