paper presents two algorithms to deal with memory page migration in the Linux Operating System. Currently Linux does not migrate memory pages when the load balancing algorithm migrates processes in a NUMA machine. This can degrade the overall system performance. One algorithm presented here is based on the idea of migrating the full process memory when the process migrates to a different computer node. The second algorithm migrates only memory pages when they are accessed by the process. The paper presents a thoroughly simulation analysis of the three strategies, i.e. full migration, on demand and the Linux current strategy.
