| 摘 要： | 网格任务调度是采用适当的调度策略把应用程序分配到异构的计算节点上进行高效的执行并返回正确结果的过程。本文研究了经典网格任务调度模型,分析了各自的优缺点,并提出了一种包含有树形全局调度模型和局部调度模型的两层结构模型,此树形全局调度模型通过负载从根节点自上而下的迁移,能够很好地实现网格系统的负载平衡。通过二叉树的节点删除算法能够很好地解决模型中节点的失效问题,因此具有很好的安全性和可靠性。

| Abstract: | Grid task scheduling is a process about how to assign applications to these heterogeneous nodes and return the outcome efficiently,which based on an appropriate scheduling strategy.In order to describe the scheduling problem exactly,firstly,this paper researched the classic grid task scheduling model and analyzed their advantages and disadvantages,presented a model consisted of tree global scheduling model and local scheduling model which based on classic model.These loads transferred from the root node to ... |
