可缩放计算系统的Cache一致性评述与研究

Survey and Analysis of Cache Coherence for Scalable Computing Systems

可缩放性是高度并行的多处理机系统的设计目标之一．为此，需要解决Ｃａｃｈｅ一致性问题，使共享数据在各处理机的Ｃａｃｈｅ中保持一致．文中分析了几种常见的Ｃａｃｈｅ一致性方案，认为分布式目录表法和基于软件的方法适用于可缩放多处理机系统．

Scalability is one of the features of highly parallel multiprocessor systems. It needs to solve Cache coherence problems to guarantee the consistency of shared data in the Caches of all processors. The paper surveys some common Cache coherence schemes and concludes that distributed directory schemes and software-based schemes are proper for scalable multiprocessors.
