Abstract: Grid resource information service (GRIS) is one of the key parts of grid infrastructure. It defines a set of mechanisms for discovery and monitoring of grid resources, and thus provides information for higher-level grid application, such as fault detection, performance analysis, and scheduling etc. Accurate obtaining, effective managing and efficient retrieving of resource information are the key technologies in GRIS. This paper proposes an approach which is based on GMA architecture and hierarchically organizes grid resource information. A Windows-oriented GRIS is designed and implemented with this approach, and it has been applied in a project.

摘要： 网格资源信息服务(GRIS)是网格基础结构的关键组成部分，它定义了一套发现和监控网格资源的机制，并以此为网格上层应用提供服务，如故障检测、性能分析、任务调度等。资源信息的准确获取、有序管理和高效检索是其中的关键技术问题。基于GMA体系结构，文章提出了一种对网格资源信息进行层次化组织管理的方法，并面向Windows平台，设计实现了基于该方法的网格资源信息服务系统。论文研究成果已在工程项目中得到实际应用。
