| 中文摘要: |
| 内存网格(RAM(random access memory) grid)是一种面向广域网上内存资源共享的新型网格系统.它的主要目标是在物理内存不足的情况下,提高内存密集型应用或IO密集型应用的系统性能.内存网格的应用效果取决于网络通信开销.在减少或隐藏网络通信开销的情况下,其性能可以进一步提高.通过对内存网格的分析,设计了一种基于"推"数据的内存网格预取机制.借助数据挖掘领域中序列模式挖掘的方法,提出了相应的预取算法.通过基于真实运行状态的模拟,对预取算法进行了评估和验证. |
| 英文摘要: |
| RAM(random access memory)Grid is a new grid system aiming at memory resources sharing in wide-area network;it can improve the performance of memory intensive or IO intensive applications when lack of physical memory.Reducing or hiding the network overhead can improve the performance of RAM Grid,which lies on the overhead of network communication.In this paper,through the analysis of RAM Grid,a “push” based prefetching mechanism is proposed for it.The corresponding prefetching algorithm,which comes from the sequential pattern mining method in data mining area,is also raised.The prefetching algorithm is evaluated and proved by trace driven simulation. |
