All three versions of eek1.in write to the same location, over-writing one another. You happen to see the results of the third process; some other time you might see the three outputs intermingled. The solutions are to have eek1.in create an appropriate output file (e.g., using mpi.comm.rank() to uniquify a base name) or to design eek1.in so that one of the nodes collates and outputs the results from all the others (i.e., only one node writes; a typical solution might include mpi.gather.Robj followed by a conditional based on mpi.comm.rank). Hope that helps. Martin > The stuff4.out file only contains the third result.
