yum list mpich* 查看有什么版本的mpich包，在此处有版本2的，所以装版本2的yum install mpich2 mpich2-devel mpich2-docwhich mpicc 发现找不到该命令find / -name "mpich" 然后会找到mpich的目录，可能会有好几个，有bin的那个就是我们要找的目录cd ~vi .bashrcMPI_ROOT=/usr/lib64/mpichexport PATH=$MPI_ROOT/bin:$PATH 这里的目录视具体情况而定source .bashrc 使之生效#include <mpi.h> #include <stdio.h> #include <math.h> int main(int argc,char* argv[]) { int myid, numprocs; int namelen; char processor_name[MPI_MAX_PROCESSOR_NAME]; MPI_Init(&argc,&argv);/* 初始化并行环境 */ MPI_Comm_rank(MPI_COMM_WORLD,&myid);/* 当前进程的ID号 */ MPI_Comm_size(MPI_COMM_WORLD,&numprocs);/* 进程的总數 */ MPI_Get_processor_name(processor_name,&namelen);/* 当前处理器的名称 */ fprintf(stderr,"Hello World! Process %d of %d on %s\n", myid, numprocs, processor_name); MPI_Finalize();/* 结束并行环境 */ return 0; }
