地震勘探集成环境资源监控研究与实现

Monitoring System for Seismic Exploration Integrated Environment

利用网格技术建设地震勘探集成环境高性能计算平台基础设施的过程中,监控系统不仅要为位于不同管理域、分布异构的高性能资源管理提供资源全局视图,方便对资源管理和控制,还要为分布环境下资源的选择、任务的调度与执行提供指导信息.本文提出了面向地震勘探领域的高性能应用网格监控系统体系结构,建立了监控信息数据模型,在Globus Toolkit信息服务组件的基础上扩展了信息采集功能和信息查询接口,并基于Websphere为高性能计算资源的信息查询与监控提供了资源实体的统一视图和可视化管理Portal.经测试,系统运行稳定,可扩展性强.

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.
