文章首先回顾了分布式共享存储器（ＤＳＭ）系统中主要的内存一致性协议，重点分析了释放一致性（ＲＣ）模型。在此模型的基础上对其进行了改进，提出了基于动态减少无效副本集的ＲＣ模型。
The article first reviews the major memory coherency protocols in distributed shared memory (DSM) systems, focusing on the Release Coherency (RC) model. Based on this model, it is improved, and an RC model based on dynamically reducing the invalid replica set is proposed.
