集群作业管理系统的关键技术分析及比较

A Core Technology Analysis and Comparison for Cluster Job Management System

集群技术是一种较新的技术,通过集群技术,可以在付出较低成本的情况下获得在性能、可靠性、灵活性方面的相对较高的收益,集群作业管理系统则是集群系统中的核心部分。讨论了集群作业管理系统中的一些关键技术,如作业调度的组织模式、作业调度策略、进程迁移机制、资源组织和管理等,据此分析比较了当今具有代表性的几种集群作业管理系统PBS,CONDOR和LSF,并由此得出了对于今后研究和开发下一代集群作业管理系统有重要指导意义的结论。

Cluster is a kind of newer technology, through which the whole network, under lower costs, can obtain higher benefits on reliability and flexibility,and cluster job management system is the core technology, this paper emphatically discusses some key technologies used in job management system, such as job scheduling organization pattern, job scheduling policy, process migration mechanism, resource management,than introduces several prevailing and representative cluster job management system,including PBS, CONDOR and LSF.
