==== Compilation ====
Go to the folder ''bin'' and generate the makefile with
<code bash>
make -f config linux
</code>

The makefile must be edited on Fedora 22. Change some lines to
<code bash>
MPIFC=/usr/lib64/openmpi/bin/mpif90

CFLAGS= -I /usr/include/X11 -L/usr/lib64/X11  -L/usr/include/X11
FFLAGS= -ftree-vectorize -I/usr/include/X11 -L/usr/lib64/X11 -L/usr/include/X11
</code>

then make.

==== Running mM with MPI ====

Load the openMPI module with
<code bash>
module load mpi/openmpi-x86_64
</code>

change the content of the file ''in/hosts.dd'' to:
<code bash>
localhost
</code>

and run e.g.
<code bash>
mpirun -N 8 -machinefile ../in/hosts.dd mmp > screen.log & 
</code>
