Reducing Cache Contention in a Multi-core Processor via a Scheduler
Multi-core architectures, which have multiple processing units on a single chip, are widely viewed as a way to achieve higher processor performance. Well scheduling of running threads on these processors will result in achieving higher performance. Modern multi-core systems are designed to allow clusters of cores to share various hardware structures, such as last-level caches, memory controllers, and interconnections, as well as prefetching hardware. Without considering these shared resources, scheduling the threads will cause serious degradation in overall performance of the system. In this paper we propose a novel algorithm to schedule the threads that considers these potential contentions to keep away from. The simulation results showed that the proposed scheduler would avoid from lots of contentions between threads on various resources especially on shared caches.
