基于微机集群系统的MPI并行计算

摘要

Computer cluster sistem 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.%计算机集群系统具有性能高、扩展性强等特点,能够充分发挥并行计算能力.在现有的微机条件上建立了基于Windows和MPI的集群计算环境,并在此平台上通过MPI并行程序设计思想,提出了利用蒙特卡罗积分法的PI值求解算法.通过对大量的PI值计算实验结果分析,发现基于MPI的并行计算能大幅度提高运算效率.
