Abstract: This paper illustrates the characters of MM subsystem in NUMA, analyzes the influence of the NUMA features to MM subsystem. Thework on supporting and optimizing NUMA is introduced, including discontiguous memory support, memory topology description and memoryallocation etc. The scheme proposed in this paper is used in the practical system. The result shows that it can well fit the need of NUMA MM, reducethe memory access latency, and enhance the system performance effectively.
