Centos7下mpich编译

编译mpich

解压源码包 最好在/tmp目录下进行，使用内存盘编译速度更快

tar xzf mpich-3.4.3.tar.gz

进入目录

cd  mpich-3.4.3

配置安装目录,指定使用CH4通信子系统，并且通过OFI接口与网络硬件进行交互

./configure --prefix=/public/software/mpich-4.0.1 --with-device=ch4:ofi

编译 加入-j自动调用所有核心

make -j

安装

make install

配置它的modulefile

在/public/software/module/tools/modules/modulefiles新建目录mpich

创建文件/public/software/module/tools/modules/modulefile/mpich/3.4.3

#%Module1.0


module-whatis "MPICH is a high performance and widely portable implementation of the Message Passing Interface (MPI) standard."

测试

新建mpic的hello.c

#include <mpi.h>
#include <stdio.h>

int main(int argc, char** argv){
    //初始化MPI环境
    MPI_Init(NULL, NULL);

    //获取进程数
    int world_size;
    MPI_Comm_size(MPI_COMM_WORLD, &world_size);

    //获取进程的等级
    int world_rank;
    MPI_Comm_rank(MPI_COMM_WORLD, &world_rank);

    //获取进程的名字
    char processor_name[MPI_MAX_PROCESSOR_NAME];
    int name_len;
    MPI_Get_processor_name(processor_name, &name_len);

    //打印helloworld
    printf("Hello world from processor %s, rank %d out of %d processors\n",processor_name, world_rank, world_size);

    //关闭MPI环境
    MPI_Finalize();
}

编译hello.c

mpicc hello.c -o hello

验证mpirun

mpirun -n 4 ./hello

验证mpirun和slurm srun提交到集群都通过
