中文摘要：

随着地球物理数据处理计算量的快速增加,使得单机运算已难以满足其计算需求。采用并行计算技术来提高处理速度是主要发展方向。为了解决地球物理数据处理中的大规模计算问题,提出基于工作站集群的并行系统架构,采用JPPF的网格计算框架,构建地球物理并行计算平台。JPPF易于使用、代码开源,利用其在并行任务管理和负载均衡方面的优势,设计并实现了一个2.5维可控源音频大地电磁正演并行系统。在实验中对频率并行和非并行的计算效率进行了对比。实验结果表明在并行计算平台硬件一定的情况下,随着频点个数的增多,该系统能够较为明显地提高计算效率。

英文摘要：

Because of the quick increase of calculated amount for geophysics data processing,it is rather difficult for one single computer to meet various kinds of computational requirements. Currently,it is a main trend to adopt the parallel computation techniques to enhance the processing speed. In order to deal with the large scale of computation work in geophysical data processing,a parallel system architecture based on workstation clusters is put forward,and JPPF grid computation framework is adopted to construct a parallel computation platform for geophysics. JPPF has open source code,and is easy to use. It is quite convenient to take its advantages in parallel task management and load balance to design and implement a forward modeling parallel system for 2.5-D CSAMT. A contrast between parallel computation efficiency and serial computation efficiency was performed in an experiment. Its results show that the system can improve its computation efficiency obviously with the increase of frequency points under a certain hardware environment of parallel computing platform.
