EIA-0203960 Marty A. Humphrey University of Virginia Legion-G: Delivering a Scalable and Secure Programming Model for Grid ComputingTo date, Grid computing lacks a secure, persistent, fault-tolerant, Grid-enabled object model that is standards-based and interoperable with the isolated Grid computing solutions that are emerging from the work in the Global Grid Forum. Grid-enabled objects must be dynamically instantiated and located, and users and administrators need to be able to better visualize performance and debugging, and graphically move objects across Grid boundaries. This project addresses these problems with three contributions. First, the lack of flexibility will be solved via the creation of Legion-G, a revolutionary "applications-level" interface of Legion to Globus. Second, new scheduling support for components across Grids will be developed. This "Continuous Scheduling" modeling will facilitate faster customization and more powerful, dynamic control of Grid-based component applications, resulting in higher performance and productivity. Third, the Grid Debugging Visualizer (GDV) will give Grid systems administrators and Grid users more precise, real-time information regarding the timing errors and functional errors of the component-based Grid computations.

Marty A. Humphrey University of Virginia Legion-G：为网格计算提供一个可扩展的安全编程模型到目前为止，网格计算缺乏一个安全的、持久的、容错的、支持网格的对象模型，该模型是基于标准的，并且可以与全球网格论坛上出现的孤立的网格计算解决方案互操作。 支持网格的对象必须动态地实例化和定位，用户和管理员需要能够更好地可视化性能和调试，并以图形方式跨网格边界移动对象。 本项目通过三个贡献解决这些问题。 首先，缺乏灵活性将通过创建Legion-G来解决，这是Legion到Globus的革命性“应用程序级”接口。 第二，将开发跨网格组件的新调度支持。 这种“连续调度”建模将促进更快的定制和更强大的，基于网格的组件应用程序的动态控制，从而提高性能和生产力。 第三，网格计算可视化工具（GDV）将为网格系统管理员和网格用户提供更精确的实时信息，这些信息涉及基于组件的网格计算的定时错误和功能错误。
