Abstract

A non-uniform memory accessing (NUMA) based multiprocessor system that promotes local memory accessing and data migration to local processor nodes. The system includes mechanisms to re-map virtual and physical addresses to promote local memory accessing and implements a least recently used memory allocation mechanism to age non-local memory accesses out of memory to be re-read into local memory, which promotes data migration to local memory on processor nodes.
