| 摘 要： | 副本管理是提高网格性能、降低客户端延迟的有效手段。针对副本部署策略问题，提出基于模拟退火算法的副本部署策略，给出优化模型及算法。OptorSim的仿真结果表明，该策略可减少作业对文件请求的响应时间，提高系统的整体性能。目前该策略已在大庆油田海量数据中心副本部署中得到成功应用。

| Abstract: | Replica management is the efficient method of improving grid performance and reducing client delay. Replica deployment strategy is the key problem of replica management. The simulated annealing algorithm is introduced to the replication deployment strategy. The optimal model and algorithm are given in this paper. The strategy is simulated using OptorSim simulator and the results show that the strategy can be effective in reducing the response time of operation which request the documents and improve the sys... |
