地震灾情和地震动力学模拟系统

摘要

Institute of Geology, China Earthquake Administration’s earthquake disaster and earthquake dynamics simulation system undertakes lots of computation tasks, such as processing of massive earthquake data and earthquake dynamics simulation. In this paper, we will introduce the construction objectives, system architecture, software environment, system operation and maintenance, system application etc., summarize the problems encountered during system operation and maintenance and corresponding solving measures, bring out a series of methods to optimize the parallel performance of HPC cluster system, and analyze the future development and improvement direction for our HPC cluster system.%中国地震局地质研究所地震灾情和地震动力学模拟系统承担着海量地震数据处理、地震动力学模拟等方面的计算任务。从系统的建设目标、系统架构、软件环境、运维和业务应用等方面进行介绍，总结了该系统在运维中遇到的问题和解决措施，提出了优化并行程序在集群系统运行性能的办法，并对下一步我所高性能计算集群系统的发展和改进方向进行分析。
