基于网格平台的GUI软件共享机制

基于网格的应用系统中存在着大量具有图形用户界面(GUI)的遗留应用软件，它们具有交互的使用模式，有很强的平台依赖性，其共享使用模式不同于一般的基于批处理的作业提交模式，给网格平台带来了一定的挑战。该文在中国国家网格(CNGrid)平台基础上，基于网格系统软件CNGrid GOS，提出并实现了一种GUI应用软件的共享系统GridShare。其原型系统的试验结果表明，GridShare能够利用网格平台的跨域安全管理和资源调度能力，实现GUI应用软件在网格环境中的共享和多用户协同使用，提高应用资源的利用效率。

GUI Software Sharing Mechanism Based on Grid Platform

The real application systems comprise a large number of legacy application softwares with Graphical User Interfaces(GUIs), which emphasize the interactive mode between human and computer, and heavily depend on specific platforms. Challenges exist when sharing and collaborating them, which are essentially quite different from the ordinary resources sharing mechanism by the method of batch processing. Based on the China National Grid(CNGrid) platform and its Grid system software CNGrid GOS, this paper proposes and implementes a sharing system for GUI applications called GridShare. From the results of the prototype system, it shows that GridShare enables to achieve the goal of sharing and collaborative use of the legacy applications among multi-users in the Grid environment, and improves the utilization of grid resources, by employing the cross-domain security management and resource scheduling capabilities provided by the Grid platform.
