网格技术在地震科学计算中的应用研究

Application of Grid Technology to Earthquake Scientific Computing

该文针对地震科学计算领域的一类问题,提出了其网格化的实现方式,包括:网格计算的系统结构、网格资源池的构成、网格应用程序的设计和开发,并在LAN上用多台PC构建的网格平台环境下,实现了这类问题的一个典型应用“地震应力触发计算”问题。同时,该文针对网格环境下使用分布式资源的问题,提出了一个结合程序设计中的多线程技术和GT3中的GRAM技术的解决方法。该方法具有通用性、易实现性。该文的研究内容对其它领域的科学计算也具有一定的适用性。

To meet a series of issues in the domain of earthquake scientific computi ng, we presents the implementing method based on grid environment. This method c onsists of the system architecture of grid computing, the construction of grid r esource pool, the design and implementation of grid application, and we have com pleted a typical application named “eathquake stress triggering computing” bas ed on the grid platform consisting of much PCs in a LAN. Furthermore, This paper a lso proposes a new method combined with multi-thread technology in programming a nd GRAM technology in GT3 for using distributed resource in grid, and this method i s general and easily realizable. The related content in this paper could be appl ied to scientific computing in other domains.
