第一步:安装MPICH2sudoapt-getinstallmpich2第二步：创建mpich2的配置文件----.mpd.conf(1)cd~(2)touch.mpd.conf(3)chmod600.mpd.conf(4)在配置文件中输入：MPD_SECRETWORD=mr.chen第三步：开启mpdbootmpdboot第四步：利用程序测试(1)mpicc-ohellohello.c(2)mpirun-np4./hello-np是指用几个进程模拟运行，这里用4个输出结果为：（下面结果每台机器可能都不一样，是正常的）HelloWorld!Process1of4oncjp-desktopHelloWorld!Process3of4oncjp-desktopHelloWorld!Process2of4oncjp-desktopHelloWorld!Process0of4oncjp-desktop第五步：停止并行运行环境mpdcleanup程序如下：
#include"mpi.h"#include<stdio.h>#include<math.h>intmain(intargc,char**argv){intmyid,numprocs;intnamelen;charprocessor_name[MPI_MAX_PROCESSOR_NAME];MPI_Init(&argc,&argv);MPI_Comm_rank(MPI_COMM_WORLD,&myid);MPI_Comm_size(MPI_COMM_WORLD,&numprocs);MPI_Get_processor_name(processor_name,&namelen);fprintf(stderr,"HelloWorld!Process%dof%don%s\n",myid,numprocs,processor_name);MPI_Finalize();return0;}
