OpenMPI installation

  • Download Open MPI source code openmpi-1.3.1.tar.gz and configure.sh
    Uncompress openmpi-1.3.1.tar.gz in your home directory on the desktop and compile it 
    tar -zxvf openmpi-1.3.1.tar.gz
cp configure.sh openmpi-1.3.1
cd openmpi-1.3.1
chmod 755 configure.sh
apt-get install g++ libc6-dev
./configure.sh
make 
make install

  • Copy the installation onto the node 
    cd /usr/local
tar -cvf openmpi.tar openmpi
scp openmpi.tar  node01:/usr/local

  • Uncompress OpenMPI on the node in directory /usr/local. 
    cd /usr/local
tar -xvf openmpi.tar

  • A user, who runs MPI, should be able to SSH between the desktop and the node without password and have the home directory located on the NFS shared system. We should have several users with Kerberos accounts, for example, user mary, who can SSH without password from the desktop to the node.

  • Add the following lines in the beginning of the user's .bashrc 
    export PATH=/usr/local/openmpi/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/openmpi/lib:$LD_LIBRARY_PATH
