 1# 有多个版本的mpi时, 默认使用路径中靠前的版本
 2
 3echo "# OpenMPI-4.1.4" >> $HOME/.bashrc
 4echo "MPI_HOME=$HOME/opt/openmpi"
 5echo "export PATH=${MPI_HOME}/bin:$PATH" >> $HOME/.bashrc
 6echo "export LD_LIBRARY_PATH=${MPI_HOME}/lib:$LD_LIBRARY_PATH" >> $HOME/.bashrc
 7echo "export MANPATH=${MPI_HOME}/share/man:$MANPATH" >> $HOME/.bashrc
 8echo ' ' >> $HOME/.bashrc
 9source ~/.bashrc

1.4.4. 卸载

The make uninstall process from Open MPI a.b.c build tree should completely uninstall that version from the installation tree. Remove the old installation directory entirely and then install the new version.
