摘　　要：调度策略是作业管理系统的关键内容,首先介绍了OpenPBS体系结构及工作原理,提出了OpenPBS中默认调度器FIFO存在的问题,然后通过分析通常的调度策略和影响调度决策的主要元素,设计和实现了多分区装填策略,最终根据模拟实验结果,分析了该策略的性能改进。Scheduling policy is the key issue in job management system. Firstly, this paper introduces the architecture and work principle of OpenPBS, and presents the problem of the default FIFO in OpenPBS. Secondly, it designs and implements multiple - partition backfilling policy based on common scheduling policies and the main elements of scheduling decision. Finally, the resuits by simulation indicate that the proposed policy develops the performance of OpenPBS.

关 键 词：调度策略 多分区装填策略 OPENPBS FIFO
