摘　　要：随着地震勘探新技术的发展和应用,地震数据量和处理量已变得越来越大。微机集群凭借其良好的性价比和高效的运算速度已逐渐成为地震数据处理的主要平台。文章以PowerEdge 175 0微机集群为例,对其体系结构进行了分析,给出了雅可比和矩阵乘积两个基准MPI程序的测试,以计算量较大的相干体算法为例,进行了实际并行计算与应用。文中给出的并行计算结果与性能分析,为推广应用该类集群提供了方法。As the development and application of the new seismic technology, the total amount and processing capacity of seismic data have become larger and larger. With its good performance cost and high operation speed, the cluster has become one of the main platforms of seismic data processing. The paper first analyzes the structure of PowerEdge 1750. Then it shows the two testing programs of Jacobi′s algorithm and Matrix multiply. As an actual example, the coherence method is applied. The result and analysis will give a reference to the use of the PC cluster on seismic data processing.
