摘要
研究Amoeba系统一个机群上进行的基于集中式负载平衡管理策略.通过在任务初始化方法中添加和未添加迁移策略的对比实验与无负载平衡管理的结果比较,表明在分布计算系统中采用负载平衡策略是完全必要的,并且可以提高系统性能.具体分析了进程迁移对系统性能的影响,为负载平衡管理在分布式系统中的应用提供了发展模式,也为迁移策略对系统性能的改进提供了依据.
Management maneuver of load balance based on centralized system, which is operated on a machine group of Amoeba system, was studied via the comparison between the contrast experiment of task initializtion with and without task transfer strategy and the result of non-load-balance management. Load balance maneuver has been proved to be necessary for the Distribute Computing System and can improve the performance, meanwhile the influence of process migration on load balance was analyzed concretely. Through the whole experiment, the development pattern of load balance management applied to the Distribute Computing System as well as the reference to the better influence of process migration on load balance are presented.
