In the construction of high-performance computing grid infrastructure for seismic exploration integrated environment, the monitoring system should not only provide a global view for distributed and heterogeneous high-performance resources in different administrative domains, but also provide guiding information for resources selection and task scheduling. A high-performance grid monitoring architecture for seismic exploration integrated environment is proposed. Then the key techniques, including monitoring information data model, information provider, information query interface and Portal, are discussed. MDS information service component of Globus Toolkit is extended and Portal system based on Websphere is developed. System testing shows that the monitor system is stable, good scalability.
