基于微機集群系統(tǒng)的MPI并行計算

　　計算機集群系統(tǒng)具有性能高、擴展性強等特點，能夠充分發(fā)揮并行計算能力。在現(xiàn)有的微機條件上建立了基于Windows和MPI的集群計算環(huán)境，并在此平臺上通過MPI并行程序設計思想，提出了利用蒙特卡羅積分法的PI值求解算法。通過對大量的PI值計算實驗結(jié)果分析，發(fā)現(xiàn)基于MPI的并行計算能大幅度提高運算效率。

　　Abstract:

　　Computer cluster system has some characteristics such as the high performance， scalable and so on， which can make full use of parallel computation ability. And it has built computing environment which is based on the Windows and MPI cluster in the existing conditions of the microcomputer ， and on this platform through MPI parallel programming ideas， presented using the Monte Carlo integration method of PI values algorithm. Based on large amounts of PI value calculation analysis of experimental results， found that based on the MPI parallel computation can dramatically improve operation efficiency.
