Dynamic Partitioning of Shared Cache Memory

WebMulti-core processors with shared last-level caches are vulnerable to performance inefficiencies and fairness issues when the cache is not carefully managed between the multiple cores. Cache partitioning is an effective … Webthe cache performance can be improved by partitioning a cache into dedicated areas for each process and a shared area. However, the partitioning was performed by collect-ing the miss-rate information of each process off-line.
