Abstract
Embodiments of the disclosure relate to the management of memory pages available for pin operations by groups of processors in a multiprocessor system to reduce cache contention and improve system performance. An exemplary embodiment comprises a system that may include interconnected processors, a global count of the number of pages available for pinning, and a plurality of local counts of pages available for pinning by groups of processors. Each local count may be in proximity to a processor group and include a subset of the pages allocated from the global count that are available for pinning by processors in the group. The local counts are adjusted accordingly in response to page pinning and unpinning by processors in the respective processor groups.
