基于我的系统考虑，我选择 mpich-3.2.x86_64 

-> sudo yum install -y mpich-3.2.x86_64 

寻找mpi命令：

-> sudo find / -name "mpicc"

发现位于：/usr/local/bin/mpicc

在.bashrc添加：

export PATH=$PATH:/usr/local/bin/mpicc

->source .bashrc

测试文件：

#include<mpi.h>

#include<stdio.h>

#include<math.h>

intmain(intargc,char** argv)

{

int myid,numproces;

int namelen;

char processor_name[MPI_MAX_PROCESSOR_NAME];

MPI_Comm_rank(MPI_COMM_WORLD,&myid);

MPI_Comm_size(MPI_COMM_WORLD,&numproces);

MPI_Get_processor_name(processor_name,&namelen);

fprintf(stdout,"hello world! Process %d of %d on %s\n", myid,numproces,processor_name);

MPI_Finalize();return0;

}
