基于UNICORE的地震网格计算应用插件
|
摘要
地震网格计算应用插件以油气地震勘探应用网格(SeisGrid)为运行框架,完成网格环境下的地震成像计算。在iCluster叠前深度偏移成像软件系统运行环境、网格计算需求和并行计算模式分析的基础上,提取适合在客户端完成的应用功能及最迫切需要在网格环境运行的计算功能,借助于SeisGrid客户端的强大网络功能和安全机制,研发了面向网格的地震应用插件。地震网格计算应用插件可方便地使用SeisGrid管理的各计算中心的网格计算资源,实现对分布式计算资源的无缝、安全和简单易行的访问,通过网络访问远程网格计算资源和iCluster应用软件资源,完成网格环境下的叠前深度偏移成像计算。
Plug-in seismic grid computing applications run on SeisGrid, an application grid for seismic exploration for petroleum, to realize seismic imaging. Based on an analysis of the running environment of prestack depth migration software system (iCluster) , requirements for grid computing, and parallel computing mode, we single out functions which are suitable for implementation at client end and running in grid environment. With the powerful network capability and security mechanism at the client end of SeisGrid, we developed plug-in seismic applications. The plug-ins can use resources that are belong to different computer centers and are managed by SeisGrid, thus provide a safe and convenient way to access to grid computing resources for applications. We demonstrated the realization of prestack depth migration in grid environment by using the plugins and iCluster.
