摘　　要：针对网格任务调度中的依赖任务调度,通过任务-资源分配图(Task-resource assignment graph,T-RAG)将描述应用静态信息的任务图与动态的网格资源结合在一起,在T-RAG的基础上提出一个面向依赖任务的网格任务调度系统框架,并基于Globus Toolkit实现了一个面向依赖任务的调度系统-DTOSS(Dependent Task Oriented Scheduling System,DTOSS).For the dependent task scheduling problem, this paper proposes a description approach： Task-resource assignment graph （T-RAG） to describe the mapping relation between task and grid resources. This graph composes the static information of grid application and dynamic information of ever changed resources together. Based on the proposed description approach, an implementation framework of dependent task scheduling system model is proposed. The Dependent Task Oriented Scheduling System, DTOSS is implemented which based on Globus Toolkit.
