并行文件系统PARFSNOW++中的Cooperative Cache技术的研究

The Cooperative Cache Techniques Used in PARFSNOW++

本文介绍了并行文件系统PARFSNOW ++中采用的有权限控制的复合协作式缓冲管理机制 ,并针对当前协作式缓冲机制中的问题 ,提出了新的全局内存数据同步和数据替换策略 .它们能有效地提高全局内存数据同步和缓冲数据替换的效率 .通过实验 ,本文证明了引入这种改进的协作式缓冲机制后 ,并行文件系统效率得到了提高 .

This paper describes the authorization-controlled cooperative cache mechanism used in the NOW based parallel file system PARFSNOW++.To solve the problems of current cooperative cache mechanisms,the paper presents a new cache coherence technique and a new data replacement technique.These new techniques can be used to improve the efficiency of the cooperative cache system.Through some test results,this paper also demonstrates that these new techniques indeed improve the performance of PARFSNOW++.
