摘　　要：并行框架可方便利用现有计算资源组建"私有云"实现石油物探的高性能计算.该框架可在windows、Linux上运行,能发挥多机、集群乃至异构设备的硬件性能,适应地震采集室内和野外软硬件环境多样、差异大的现况.并行框架采用"平台+插件+工作流"方式实现,并利用"平台+插件"的方式提供可靠的多机运行环境;定义了一套通用插件接口,用户可以在不修改程序主体的情况下,以插件方式实现不同的并行算法,并"即插即用"的利用并行框架实现多机并行计算;实现了一套针对物探应用的多机并行计算过程规范,不但可定制复杂的作业流程,而且可以按流程来组织插件和网络资源高效的运作.并行框架以一种通用技术手段解决了物探算法种类多样、算法流程复杂、多机实现困难的问题,满足不同用户的差异化需求.基于此框架已经完成多个课题并行程序的开发与应用,极大的节省了计算时间.The multi-computer parallel-computing framework can achieve high performance computing of geophysical prospecting by building a ＂private cloud＂ using available computing resources. The framework can run on different operating systems such as Windows and Linux. By exploiting the hardware performances of interconnected computers, clusters and heterogeneous equipment, it can be widely used in laboratory and field processing. With the method of ＂platform＋plug-in＋workflow＂, the framework is a parallel-computing platform and responsible for background work. A set of common plug-in interfaces is designed on the framework. Through plug-and-play parallel framework, user can achieve different parallel algorithms using plug-ins without modifying the framework and realize multi-computer parallel computing. A parallel computing process specification, which can not only customize complex workflow, but organize plug-ins according to the workflow and make good use of network resources, is completed for geophysical application. With a general technique method, the problems such as various algorithms, complex algorithm process, multi-computer implementation difficulties are solved to meet the needs of different clients. Many applications have been developed and applied on the framework with the calculation time being greatly saved.
