(English Abstract)
As the number of cores in computer systems with NUMA architecture is increasing, the contemporary operating systems are not scalable because of increased cache misses, cache coherence activities and synchronizations. To resolve this problem, several studies have suggested controlling the core affinity of the system calls and the event handlers, making these run on a specific set of cores. However, these core partitioning approaches statically decide the number of cores available for controlling the core affinity without considering the characteristics of the applications and the system architectures. In this paper, we propose a dynamic core affinity scheme for the core partitioning and compare with a static core partitioning mechanism.
