Dedicated and shared central processors

Generally, LPs with dedicated CPs require fewer processing resources. The internal throughput rate (ITR) of LPs with dedicated CPs is higher than that of identically defined LPs with shared CPs. It is recommended that dedicated ICFs be used in a coupling facility partition that is used in a production configuration.

Generally, the capability to recognize CP resources that are not used and to balance workloads can result in an improved ETR for LPs with shared CPs. In particular, for workloads that exhibit fluctuations in processing demands, the consolidation of several systems as LPs with shared CPs on a CPC can improve responsiveness and increase ETR.
