Dedicated central processors

An LP can have CPs dedicated to it. When an LP that uses dedicated CPs is activated, a physical core is assigned to each defined logical core. The LP then has exclusive use of its physical cores.

The physical cores that belong to an LP that uses dedicated CPs are always available for its use, but the capacity that is not used cannot be used by other LPs.

Dedicated central processors cannot be used in a coupling facility partition.

Use the Customize/Delete Activation Profiles task to open a reset or image profile to define dedicated CPs for an LP. The Dedicated field is located in the Logical processor assignment group box on the Processor page for the LP.
