| The technology of modern computer has stimulated the rapid growth of thecomputational science.At the same time,because of developing of science,the sciencedemand of high performance of computing.The PC performance have moreeffective ,but the limit of speed and technology has embarrassed the PC to be usedwidely.There two methord to solve the problem.The first one is to make more highperformance computer,the other is to use parellel Computing.There are two kind ofmethod to achieve parellel calculation,One is use special parellel computer ,it isvery expensive. Few people can afford it.Another is cluster of PCs.Becuase it is cheapand easy,more and more people use it.Technology of cluster of PCs depand on network.The network speed influencethe development of technology of cluster of PCs. The network speed improvequikly so the cluster of PCs is used more and more .In abroad,some of standard ofparallel calculation are be developed and used well.The standard to design parallel program include MPI,PVM, and so on. Becauseof theadvantage of the MPI (Message Passing Interface), which are portal,powerfulfunction, and high efficiency, it became the most important tool to design parallelprogram.In this paper ,I user MPI standard to develop parallel program.This paper introuduces how to build a cluster of PCs ,the baisc theory ofparallel calculate and how to design and establishes parallel program base on MPI.Then a prarllel calculate program base on MPI is build to solve Magnetotelluricforward modeling calculate.Finally ,from the theoretic and practical sutdy, thefeasibility of proceeding parallel calculation base on cluster of PCs was discussedand some meaningful conclusions were also achieved. |
