【摘要】 基于CEDAGrid项目的需求,通过应用Web服务技术和网格计算技术,构建了基于GT3的网格计算应用平台,在有4个节点的网格计算平台上(其中只有3个节点参与了科学计算任务)进行了地震应力触发计算实例(以川滇地区为例,共有17个断层),系统耗时为13min25s,如果只在一个节点上进行计算,则需要时间为35min10s。该实例的成功运行证明,基于网格技术构建的计算平台可以解决传统的地震领域内的科学计算问题,在时间效率上可以提高许多,如果应力触发计算本身越复杂,网格的计算资源越丰富,网格计算的执行效率会体现的越优越。通过这一科学计算试验为网格技术在地震领域的应用做了有意的探索。更多还原

【Abstract】 Based on requirement of the project CEDAGrid,the paper describes the construction of Grid based computation platform on the basis of Web service technology and Grid computing technology,and the successful deployment of a realistic computation of the earthquake stress triggering on the platform(only 4 nodes).The whole process expends 13m25s on the platform,and it’s 35m10s on only one node of the platform.The successful deployment of the instance proves that Grid computing technology can resolve many traditional science-computing problems of the seismological fields.The effort of this work gives a meaningful experiment on the application of Grid technology to earthquake scientific computing.更多还原
