Linux系统centOS安装mpich

操作系统为centOS7

一、下载并安装mpich-3.4.1

进入安装包目录并下载mpich安装包

cd /opt/software
wget http://www.mpich.org/static/downloads/3.4.1/mpich-3.4.1.tar.gz

安装包解压到当前目录

tar -zxvf mpich-3.4.1.tar.gz

在当前目录下生成解压后的文件夹mpich-3.4.1

进入解压后的文件夹并开始安装

cd mpich-3.4.1/
sudo ./configure --prefix=/opt/module/mpich-3.4.1 --with-device=ch4:ofi
configure后报错
configure: error: No Fortran 77 compiler found. If you don't need to
        build any Fortran programs, you can disable Fortran support using
        --disable-fortran. If you do want to build Fortran
        programs, you need to install a Fortran compiler such as gfortran
        or ifort before you can proceed.
根据提示在末尾加上--disable-fortran指令

sudo ./configure --prefix=/opt/module/mpich-3.4.1 --with-device=ch4:ofi --disable-fortran
注：--prefix后为设置的mpi安装路径

编译安装

（时间较长）
sudo make
sudo make install

安装后在/opt/module/mpich-3.4.1路径下生成bin、include、lib、share四个文件夹

二、配置环境

vim ~/.bashrc

在bashrc文件最底下添加环境变量

export MPI_ROOT=/opt/module/mpich-3.4.1
export PATH=$MPI_ROOT/bin:$PATH
export MANPATH=$MPI_ROOT/man:$MANPATH

环境生效

source ~/.bashrc

配置成功验证

mpirun -version

mpi配置成功示意图
