基于ExtJs的集群作业调度策略配置系统的设计与实现

摘要

Based on ExtJs framework, using javabean, jsp and open source database Mysql, this pa-per has designed and implemented a configuration system of cluster job scheduling policy aim at the com-plexity and fallibility of the scheduling policy configuration of PBS in order to reap the cluster perform-ance. This paper sovled the technical problems such as the selection of controls for chosen scheduling policy, the combination of front-end process and back-end process for the input parameters verifica-tion, the generation of scheduling policy combinations in the interface file, user information paged-dis-play , focusing on the implementation of remote configuration and automatic generation of sophisticated job-scheduling policies. The system’ s major modules design idea, the core function and their implementa-tion method are introduced in detail. The running results show that the system improves the efficiency of the scheduling policy configuration work of high performance computing clusters adopting PBS, improve the accuracy of sophisticated job-scheduling policies generated.%为充分发挥集群系统的性能，针对PBS调度模块配置调度策略工作繁复、易于出错的问题，该文基于ExtJs框架，采用javabean、jsp、Mysql等技术设计并实现了一种集群作业调度策略配置系统。该系统解决了针对选定辅助策略的控件选取、输入参数的前后台联合校验、针对接口文件的组合调度策略生成、用户数据的分页显示等技术问题，重点实现了PBS的组合调度策略的远程配置及自动生成的功能。详细介绍了系统主要模块的设计思路、核心功能及实现方法。运行结果表明，该系统能够有效提高使用PBS的高性能计算集群的调度策略配置工作的效率，提高生成的较复杂的调度策略的正确率。
