在PC Cluster机群中实现批量常规地震资料数据处理

CONVENTIONAL BATCH SEISMIC DATA PROCESSING HAS COME TRUE IN THE PC CLUSTER AIR FLEET

LinuxPC服务器的磁带I/O能力较差,数据传输也受到网络带宽的限制,在大规模地震数据处理中存在严重的瓶颈。本文通过对PC机群的体系结构的分析,结合OMEGA应用软件用于常规处理的实际需求,从配置外置盘阵、磁带机,连接自动带库,合并多块磁盘成一个大卷,增加网络接口以提高传输带宽等多方面介绍了PC机群整体性能的技术改进过程,以满足常规地震数据处理的需要。

The I/O ability of Linux PC server tap is poor and data transmission is limited by bandwidth. There is a big bottleneck problem in the large-scale seismic data processing. It is introduced in this paper that PC air fleet overall performance is improved in view of technology to adapt to the need of the conventional seismic data processing, which is implemented by analyzing PC air fleet system structure combined with the practical need to conventional processing. The related respects consist of allocating outer-installed tray blast, tape transport, connecting automated tape library, unifying mult-disks to be a big volume and add more interfaces to enhance transmission bandwidth.
