Regardless of any mpi implementation , there is always a command

Er, no. There are some that I have used that do not have such a
command at all, and some where it is a script in some shell language,
Python or Perl. I believe that OpenMPI usually makes it a symbolic link
to some other command (orterun or mpiexec), and so do some others.
I believe mpiexec is actually the command specified in the MPI spec
which can be a link. However, the command, in OMPI, that ends up doing
the real business orterun and its base source is
orte/tools/orterun/orterun.c.
--td
It's trivial to write a simple wrapper for mpiexec for your own use and
call it mpirun. Or just create a symbolic link.
Someone else has indicated that OpenMPI intends to set up such a command,
but I am not commenting on that aspect.
