摘要： 针对桌面网格中出现的应用部署难、作业结果差异大、系统可扩展性差等问题，基于虚拟化技术提出一种桌面网格架构。利用虚化技术的隔离性和封装性，通过面向应用的作业调度策略以及有限生命周期的虚拟机控制方式，实现一个易于扩展且易于部署的桌面网格架构。分析及测试结果表明，该架构适用于大规模应用场景，架构中所采用的面向应用的调度策略以及虚拟机控制方式是有效可行的。

Abstract: In this paper, a desktop grid architecture is proposed with virtualization technologies to solve the problems of porting cross platform applications, discrepant results from heterogeneous platforms and system scalability. Based on the isolation and encapsulation of virtualization technology, with application-oriented job scheduling policy, a finite virtual machine controlling method, scalable and easily- deploying desktop grid architecture is achieved. The test results demonstrate that this new architecture well applies to large-scale scenarios, and the application-oriented scheduling policy and virtual machine control method are effective and feasible as well.

Key words: massive data, desktop grid, architecture, virtualization technology, application-oriented, virtual machine controlling
