跨大西洋的WorldGrid测试平台：跨EU和美国域的网格互操作性的成功实例
The WorldGrid transatlantic testbed: a successful example of Grid interoperability across EU and U.S. domains
摘要：
欧洲DataTAG项目朝着实现全球计算网格的概念迈出了重要的一步。DataTAG与美国的iVDGL项目合作，实现了一个横跨欧洲和美国的洲际测试平台，该平台基于Globus工具包集成了架构上不同的网格实现。WorldGrid测试平台已在SuperComputing 2002和IST 2002上成功演示，在这些平台上，使用本地机制从美国和欧洲透明地提交了真正的HEP应用程序作业，并在资源可用的地方运行，而与其位置无关。在本文中，我们描述了WorldGrid测试平台的体系结构，遇到的问题和实现这样的测试平台所采取的解决方案。通过我们的工作，我们提出了一个重要的一步，在欧洲和美国开发和部署的网格中间件的互操作性。WorldGrid中开发的一些解决方案将被LHC计算网格第一服务采用。据我们所知，这是第一个结合中间件组件并使它们协同工作的大规模测试平台。
英文摘要：
The European DataTAG project has taken a major step towards making the concept of a worldwide computing Grid a reality. In collaboration with the companion U.S. project iVDGL, DataTAG has realized an intercontinental testbed spanning Europe and the U.S. integrating architecturally different Grid implementations based on the Globus toolkit. The WorldGrid testbed has been successfully demonstrated at SuperComputing 2002 and IST2002 where real HEP application jobs were transparently submitted from U.S. and Europe using native mechanisms and run where resources were available, independently of their location. In this paper we describe the architecture of the WorldGrid testbed, the problems encountered and the solutions taken in realizing such a testbed. With our work we present an important step towards interoperability of Grid middleware developed and deployed in Europe and the U.S.. Some of the solutions developed in WorldGrid will be adopted by the LHC Computing Grid first service. To the best of our knowledge, this is the first large-scale testbed that combines middleware components and makes them work together.
