| 摘 要： | 对于具有共享缓存结构的多核处理器,存在并行应用对共享缓存冲突访问导致性能下降的现象.为合理地分配共享缓存以有效地解决这类问题,提出了一种共享缓存分配方法,通过将并行应用对共享缓存访问未命中的情况进行分类与追踪,并根据建立的性能增益模型在行的粒度上进行动态地分配共享缓存,使系统的整体性能得到改善.实验结果表明,新算法能合...

| Abstract: | It was found that on access which causes the conflict between parallel applications and shared cache will lead the system performance to degrade for the multi-core processor involving a shared cache.To solve the problem efficiently and reasonably,allocation algorithm is proposed for the shared cache,i.e.,sorting and tracking the cases the parallel applications are missing the access as a target to shared cache,then the shared cache is allocated dynamically for cache's line granularity according to the perfo... |
