GRAPPA：物理应用网格访问门户
GRAPPA: Grid Access Portal for Physics Applications
摘要：
Grappa是一个网格门户，旨在为物理学家提供方便的网格工具和服务。ATLAS分析和控制框架Athena被用作目标应用程序。Grappa提供了基本的网格功能，如资源配置、证书测试、作业提交、作业监控、结果监控以及与ATLAS副本目录系统MAGDA的初步集成。Grappa使用Jython将脚本的易用性与基于Java的工具包的强大功能结合起来。这提供了一个强大的框架，访问不同的网格资源与统一的接口。最初的原型系统基于印第安纳大学极限计算实验室开发的XCAT科学门户，并通过在美国ATLAS测试台上运行Monte Carlo生产进行了演示。作为IST 2002和SC 2002演示的iVDGL-DataTAG互操作性联合项目的一部分，该门户还与WorldGrid上的一个欧洲资源代理进行了交流。当前的原型用xbooks jetspeed portlet代替了XCAT Science Portal，用于管理用户脚本。
英文摘要：
Grappa is a Grid portal effort designed to provide physicists convenient access to Grid tools and services. The ATLAS analysis and control framework, Athena, was used as the target application. Grappa provides basic Grid functionality such as resource configuration, credential testing, job submission, job monitoring, results monitoring, and preliminary integration with the ATLAS replica catalog system, MAGDA. Grappa uses Jython to combine the ease of scripting with the power of java-based toolkits. This provides a powerful framework for accessing diverse Grid resources with uniform interfaces. The initial prototype system was based on the XCAT Science Portal developed at the Indiana University Extreme Computing Lab and was demonstrated by running Monte Carlo production on the U.S. ATLAS test-bed. The portal also communicated with a European resource broker on WorldGrid as part of the joint iVDGL-DataTAG interoperability project for the IST2002 and SC2002 demonstrations. The current prototype replaces the XCAT Science Portal with an xbooks jetspeed portlet for managing user scripts.
