| 摘 要： | 随着叠前偏移处理技术的进一步推广应用，大规模PC集群已取代传统并行机成为地震资料处理的高性能计算机系统。针对PC集群存储的I／O瓶颈问题，对近年来在PC集群地震资料处理系统中常用的存储技术进行了研究，在辽河新扩充的PC集群地震资料处理系统中采用具有全局共享文件系统SAN、高速磁盘阵列及条带化文件系统等技术，较好地解决了PC集群中容易产生的I/O瓶颈，为叠前处理技术的应用提供了良好的计算环境。

| Abstract: | As the popularization of prestack migration processing technique, large scale PC group has replaced traditional parallel cluster and become a high performance computer system for seismic data processing. In accordance with the I/O bottleneck problem in PC group storage, conventional storage technique used in recent years has been studied. Shared document system SAN, high-speed disc array and stripe document system have been used in new PC groups of seismic data processing system in Liaohe oilfield, thus solved the I/O bottleneck problem and provided good computing environment for application of prestack processing technique. |
