COMPUTER ARCHITECTURE WITH CACHING OF HISTORY COUNTERS FOR DYNAMIC PAGE PLACEMENT

A multi-processor system using distributed memory is provided with a cache of history counters located within each memory controller. Each entry of the cache of history counters represents one page in memory that has the potential to increase system performance by migrating or replicating to other memory locations. The cache of history counters permits creating histories of local memory accesses by remote processors for purposes of dynamic page placement.
