# this is a runscript for running mppnp in MPI parallel mode on a number
# of machines;
# if you use a machines file, copy it into the RUN directory. for example
# on helix@Uvic a machines template file is in helix: /rpod2/fherwig/TOOLS
# together with a  mntrpod2.sh   script that you need to run to make sure
# that rpod2 is mounted on all participating machines

# the lcoation of mpiexec should now be provided by the system, either
# done through the use of modules on supercomputers or through the
# PATH variable in .bashrc
# (however, it seems we still need to call this with a full path name
# and we try to understand why)
