摘　　要：在现阶段,网格的计算池模型是一种较实用的网格实现方式,其资源的查找和分配机制也相对简单。文章根据计算池模型的特点,参照织女星网格的体系结构,将基于最短路由转发的资源发现机制与任务调度算法相结合,提出了一种新的网格任务调度策略,并给出了简化模型清晰地描述了任务在此策略下全部的执行过程。At present time,computing pool is a practical computing grid model.The mechanisms of its resource discovery and allocation are more simplified.According to the features of computing pool and the architecture of Vega grid,the short paper combines a resource discovery mechanism based on shortest distance routing-transferring and a job scheduling algorithm,proposes a new task scheduling strategy.Then a simplified model is designed,which distinctly describes a whole process of a job being executed.
