摘要
作业迁移是实现网格作业服务质量保证和系统高效能的重要方法,在分析了传统进程迁移技术的基础上,根据网格系统的特点,提出了一种基于代理的网格作业全局自适应迁移模型,通过设计网格作业全局自适应迁移对象选定原则、迁移时机确定机制和作业迁移信息监控管理,解决了网格环境下作业迁移的关键问题.试验结果以及在西北工业大学校园计算网格中的实际应用验证了模型的有效性.
Job migration is essential to guarantee the Quality of Services of Grid jobs and the high efficiency of grid system.Based on the feature of grid system,analyzing traditional process migration technology,a self-adapting job global migration model based on agent is presented,a self-adapting global determining principle about migration object and time,monitoring and controlling information of job migrated are given to solve key problems with regard to job migration well under grid.Preliminary experiment results and applications to Northwestern Polytechnical University Campus Computational Grid confirm the validity of this model.
