Abstract:

We present an application of high performance computing cluster in the field of earthquake science.  First we analyze the calculation characteristics of earthquake data processing and the earthquake dynamics simulation, and highlight the performance requirements of the earthquake science study for high performance computing platforms. Taking the earthquake data processing and earthquake dynamics simulation platform of Institute of Geology, China Earthquake Administration as an example, we introduce the platform architecture, the software environment, system operation and maintenance, system application etc. More importantly, we introduce the optimization measures for the system, and discuss the ways of improving the operating efficiency of the cluster system from the perspectives of service application, users and management.
