Counted among the most dramatic predictions of general relativity are black holes and gravitational waves. Scientists are now poised to probe general relativity, black holes and the early universe using the Laser Interferometer Gravitational-wave Observatory (LIGO) as an astronomical tool. The success of LIGO's long-term observing campaign is predicated on continuing timely analysis of the observational data. To achieve this non-trivial computational task, LIGO has successfully adopted the grid computing model and has been at the forefront of its application for data-intensive observational science. This award supports the LIGO Data Grid, a distributed computational facility developed specifically to meet the significant computational needs of gravitational-wave astronomy. It provides personnel to support, enhance and deploy software and grid-services on the LIGO Data Grid. It addresses the needs of the community of gravitational-wave physicists involved in LIGO data analysis, and will have significant impact in that area. The LIGO Data Grid also tests grid concepts at both the high level of grand ideas and at the detailed level of tools in everyday use for a large scientific experiment. This experience will have broad relevance for other grid and information technology initiatives. Finally, this award will provide training for students, scientists and computer specialists in the use of emerging cyber-technology which has applications outside LIGO's endeavor.

广义相对论中最引人注目的预言包括黑洞和引力波。科学家们现在正准备利用激光干涉仪引力波天文台（LIGO）作为一种天文工具来探测广义相对论、黑洞和早期宇宙。LIGO长期观测活动的成功取决于对观测数据的持续及时分析。为了完成这一重要的计算任务，LIGO成功地采用了网格计算模型，并将其应用于数据密集型观测科学的前沿。该奖项支持LIGO数据网格，这是一种专门为满足引力波天文学的重要计算需求而开发的分布式计算设施。它提供人员来支持、增强和部署LIGO数据网格上的软件和网格服务。它解决了参与LIGO数据分析的引力波物理学家社区的需求，并将在该领域产生重大影响。LIGO数据网格还在一个大型科学实验的日常使用中，在高层次的宏大构想和详细的工具层面上测试网格概念。这一经验将对其他网格和信息技术倡议具有广泛的相关性。最后，该奖项将为学生、科学家和计算机专家提供培训，帮助他们使用新兴的网络技术，这些技术在LIGO的努力之外也有应用。
