Research of Grid Platform Oriented to Intensive Data Processing

Aiming at 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 information acquirement service, grid resource management service, data access and integration service, which can realize grid resources sharing, intensive data access and processing. In the grid resource management service, a resource management model for grid computing 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.
