摘要：

基于网格副本创建的可靠性,介绍了网格模拟器OptorSim自带的几种副本优化算法,提出了DMRC副本优化算法,并详细阐述了该算法的思想。通过对DMRC算法和现有副本优化算法在时间和空间两方面进行仿真分析,得出了DMRC算法在网格环境下某些性能优于OptorSim自带的一些算法的结论。

Abstract:

Focusing on the reliability of the grid replica creation, several kinds of grids optimization algorithm mainly studied in OptorSim were introduced. A replica of DMRC optimization algorithm was put forward and the idea of the algorithm was expounded in detail. The time and space simulation analysis on DMRC algorithm and the existing replication optimization algorithm show that some of DMRC algorithm performance is better than some algorithms of OptorSim in the grid environment.
