【摘要】 网格环境中集成了大量的用户和资源,任务调度对系统良好地运行起着极其重要的作用。本文提出网格系统中一种基于多服务器多队列的集中式的任务调度模型,并给出模型的随机进程代数的描述和性能评价与分析技术,实验结果表明该模型能较好的模拟网格系统中任务处理与调度。研究结果提供了形式化描述调度模型,为大规模和复杂的网格系统的建立提供了定量分析和预测评价。更多还原

【Abstract】 A Grid system integrates and coordinates resources and users that live within different control domains in order to deliver nontrivial quality of service.So,resource management and task scheduling is of central importance for Grid system.In this paper,a centralized control MultiServer MultiQueue(MSMQ)system to model the task scheduling is proposed in Grid system,and gives a modeling and analysis technique based on Stochastic Process Algebras(SPA)to evaluate its performance.Our research provides formal description results for MSMQ model in Grid system.In general,the results provide new and efficient solution to the type of MSMQ and performance evaluation of complicated Grid system.更多还原
