中文摘要: 网格是近年来最新发展起来的一种计算技术。通过使用一组开放标准与协议,各机构能够通过互联网或内部网访问数据、存储介质和其它异构计算资源,最终将分布在不同地理位置上的网络、数据、计算资源、存储、应用等在内的资源整合成为一个无缝的计算环境。气象以其高计算量、高吞吐量和密集型服务在美国、欧洲、日本等网格应用计划中占有重要的地位。如ECMWF的EcAccess ,美国超级计算应用中心的MEAD等。这些计划的实施将有效地聚合分布在不同地理位置上的高性能计算资源与人力资源,实现计算资源和气象数据的共享,为数值预报乃至地球系统模拟提供一个远程的协同攻关环境。
Abstract:Grid computing has emerged as an important new field. Based on an open set of standards and protocols, grid computing enables the organizations around the world to access the data resources, storage capacity and the distributed heterogeneous computing etc. via internet or local network to create a single system image, ultimately it can grant users and applications seamless access to vast computing environments. Because of its huge computing requirement, high throughput and dense service, meteorology has become one of the significant application fields in the proposed world's grid projects, such as ECMWF's EcAccess system, MEAD Project of US, Europe, Japan, etc. With grid computing, organizations can optimize distributed heterogeneous computing, human expertise and data resources, can share them across networks and can provide a remote collaborative environment for NWP as well as the Earth simulation system.
