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.
