基于Globus网格平台的电子工程预算软件作业调度实现

Globus-based Grid Platform Electronic Engineering Budget Job Scheduling Software Implementation

作业调度是能否充分发挥网格性能的关键技术。基于SaaS模式的电子工程预算软件(SaasBudget)为用户提供一个动态、实时、高可用性的预算软件平台。SaasBudget基于Globus Toolkit4网格平台实现,利用网格提供的强大计算性能和分布式处理能力进行大工程的项目预算计算。通过对Globus作业调度机制的研究,设计了SaasBudget系统的作业调度系统。实验结果表明,该作业调度系统能够综合考虑任务与计算节点的特性,并能根据任务当前运行情况实时进行调整,有效改善了作业调度效率,大大提高了网格资源的利用率。

Job scheduling are able to give full play to the grid properties of key technologies. Based on the SaaS model of software project estimates Electronics （SaasBudget） to provide users with a dynamic, real-time, high-availability software platform budget. SaasBudget based on Globus Toolkit 4 grid platform implementation, the use of grid computing to provide powerful performance and distributed processing capabilities Major projects for budgetary calculations are presented. Through the Globus job scheduling mechanism, designed SaasBudget system job scheduling system, experimental results show that the job scheduling system be able to consider the mission and the General characteristics of computing nodes and the current mission in accordance with the operation of real-time adjustments, effectively improved the job scheduling efficiency, greatly improving the utilization of grid resources.
