Uma proposta para migração de páginas no Linux

Guilherme A. A. TesserAvelino F. Zorzo

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.
