Global-State Aware Automatic NUMA Balancing
Jianguo Liu, Zhibin Yu · 2024
Non-uniform memory access (NUMA) has become a standard architecture for modern servers. However, NUMA effect (i.e., local memory access typically takes shorter time than remote memory accesses) is unavoidable. To address this issue, Automatic NUMA Balancing(Auto-NUMA) was proposed. Nevertheless, Auto-NUMA can improve or hurt performance of an application, depending on its characteristics which is difficult for end users to know.
