The Seismic Processing Patterns and Application Framework

文中研究石油地震数据处理的并行计算设计模式 (流水、扇出 /扇入、主从和混合 )和应用框架 .框架和模式的目的都是复用成功的软件设计策略 .框架可以看作一类设计模式的具体实现 .针对地震数据处理模式设计和实现了 GRISYS地震数据处理应用框架 .利用这个框架 ,以往大量的串行地震处理模块 ,不需要任何改动 ,可以在工作站集群计算机或大规模并行计算机上实现并行计算 .在曙光 2 0 0 0 - II并行计算机上试验 ,获得了非常高的并行处理加速比 .

The Paper describes design patterns (namely pipeline, fan-in/fan-out, master-slave and hybrid pattern) and application framework for seismic data parallel processing. Frameworks and patterns both facilitate reuse by capturing successful software development strategies. Frameworks can be viewed as a concrete realization of families of design patterns that are targeted for a particular application-domain. The GRISYS application framework has been designed and implemented based on these seismic processing patterns. With the use of this application framework, we are able to achieve parallel data processing on workstation clusters or massive parallel computers, without any revision of multitudinous serial processing modules. Parallel processing splits this type of processing modules over many processors to cut down overall computing time. It extended specific geophysical language by providing parallel statements. GRISYS can perform 2D and 3D imaging of seismic data to produce images of the subsurface. The job examples of 3D data processing have been benchmarked on Dawning 2000-II computer to examine the performance of GRISYS parallel framework.
