If you are using scheduler like PBS or SGE over MPI, there is an option
called prolog and epilog, where you can give scripts which does copy
operation. This script is called before and after job execution as the
name suggests.

        Without it, in mpi itself, i have to see, if it can be done.

The alternative way is to keep copy of the program at the same location
on all compute nodes and launch mpirun.

If the executable location is different on compute nodes, you have to
specify the same as the mpirun command-line arguments.
