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。本文以PowerEdge1750微机集群为例,首先对其体系结构进行了分析,然后给出了雅可比和矩阵乘积两个基准MPI程序的测试,最后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借鉴。With development and application of new seismic exploration technology, the quantity of seismic data and processing rate are becoming larger and larger.Microcomputer cluster has become the main platform of data processing by right of its favorable performance price ratio and high operation speed.This paper takes PowerEdge 1750 microcomputer cluster as an example. It analyses the architecture first, then gives out the testing result of two basic standard MPI programs Jacobian and matrix multiplication. Practical parallel computation and application are carried out basd on the coherent algorithm which has larger amount of calculation.The parallel computation result and performance analysis will provide reference for generalizing this kind of cluster.
