Abstract

In a computer system that includes multiple nodes and multiple logical partitions, a dynamic partition manager computes current memory affinity and potential memory affinity at the request of a logical partition to help the logical partition determine whether a reallocation of resources between nodes may improve memory affinity for the logical partition. If so, the logical partition requests reallocation of resources by the dynamic partition manager so memory affinity for the logical partition is improved.
