There are a few freely available MPI libraries around; among the most widely spread are the OpenMPI and MPICH libraries
Checking if you have an Fortran enabled MPI library already installed and at hand
This can easily be done by checking if the MPI wrapper mpif90 is available, i.e. that
which mpif90
returns something meaningful
Example of installing the OpenMPI library
To adapt to fit your onw needs and system specificities, obviously. In the example below the installation is done in the $HOME/LMDZ directory (for convenience this path is stored in the PATH_OPENMPI variable.
PATH_OPENMPI=$HOME/LMDZ/
mkdir -p $PATH_OPENMPI
cd $PATH_OPENMPI
wget https://www.open-mpi.org/software/ompi/v1.10/downloads/openmpi-1.10.3.tar.gz
gunzip openmpi-1.10.3.tar.gz
tar xvf openmpi-1.10.3.tar
cd openmpi-1.10.3
./configure --prefix $PATH_OPENMPI/openmpi-1.10.3
make all install
To check that the install went well check that
$PATH_OPENMPI/openmpi-1.10.3/bin/mpif90 -V
returns something meaninful
