讨论了分布式共享存储系统（ＤＳＭ）的通用结构及页面管理机制，给出了各种存储一致性模型的正确性条件，并以互斥问题为例，说明了在分布式环境下编程的一些特点．最后，基于作者本人的工作，还讨论了如何提高ＤＳＭ系统性能的问题．
This paper discusses the general structure and page management mechanism of distributed shared storage system (DSM), and presents the correctness conditions of various storage consistency models. Taking the mutual exclusion problem as an example, it shows some of the programming in distributed environment Features. Finally, based on the author’s own work, but also discussed how to improve the DSM system performance issues.
