WASP: Workload-Aware Self-Replicating Page-Tables for NUMA Servers

Recently, page-table self-replication (PTSR) has been proposed to reduce the page-table caused NUMA effect for large-memory workloads on NUMA servers. However, PTSR may improve or hurt performance of an application, depending on its characteristics and the co-located applications. This is hard for users to know, but current PTSR can only be manually enabled/disabled by users.
