    摘要: A method, system, and product are described for creating and managing affinity between memory and processors in logical partitions in a data processing system. The data processing system includes multiple processors. A memory affinity data structure is established. The memory affinity data structure identifies ones of the processors that have a close affinity with each one of multiple regions of the system memory. A memory affinity parameter is established and is utilized to determine whether memory affinity is required for each one of the logical partitions. In response to a determination that memory affinity is required for one of the logical partitions, the memory affinity data structure is utilized by a partition manager for the logical partition to allocate an optimal amount of memory that has a close affinity to ones of the processors that are assigned to the logical partition.
