NUMA SYSTEM AND METHOD OF MIGRATING PAGES IN THE SYSTEM

Abstract:

Remote access latency in a non-uniform memory access (NUMA) system is substantially reduced by monitoring which NUMA nodes are accessing which local memories, and migrating memory pages from the local memory in a first NUMA node to the local memory in a hot NUMA node when the hot NUMA node is frequently accessing the local memory in the first NUMA node.
