摘　　要：针对网格环境下的密集数据处理,构建了网格平台IDPGP.该平台基于Globus Toolkit 4、OGSA-DAI、Condor和PBS,主要提供网格信息服务、网格资源管理、数据访问与集成等服务,实现网格资源共享,完成密集数据的读取与处理.在网格资源管理服务中设计了一个基于分层模型的计算资源管理模型,既保证了每个虚拟域的一致性和可管理性,又增强了整个平台的可扩展性和容错能力.Aiming at the intensive data processing in grid environment, a grid platform IDPGP is constructed based on Globus Toolkit 4, OGSA-DAI, Condor and PBS. This platform mainly provides grid in-formation service, grid resource management service, data access and integration service. On the basis of these services, the grid resource sharing and intensive data access and computing are realized. In grid resource management service, a computing resources management model based on hierarchical model is designed to ensure consistency and manageability of each virtual domain and enhance scalability and fault-tolerability of the entire platform.
