SYNOPSIS
       Single Process Multiple Data (SPMD) Model:

       mpirun [ options ] [ ]

       Multiple Instruction Multiple Data (MIMD) Model:

       mpirun [ global_options ]
              [ local_options1 ] [ ] :
              [ local_options2 ] [ ] :
              ... :
              [ local_optionsN ] [ ]

       Note  that in both models, invoking mpirun via an absolute path name is
       equivalent to specifying the --prefix option with a value equiva-
       lent  to  the  directory where mpirun resides, minus its last subdirec-
       tory.  For example:

           % /usr/local/bin/mpirun ...

       is equivalent to

           % mpirun --prefix /usr/local

QUICK SUMMARY
       If you are simply looking for how to run an MPI application, you proba-
       bly want to use a command line of the following form:

           % mpirun [ -np X ] [ --hostfile ]  

       This  will  run X copies of in your current run-time environ-
       ment (if running under a supported resource manager, Open MPI's  mpirun
       will  usually  automatically  use  the  corresponding  resource manager
       process starter, as opposed to, for example, rsh or ssh, which  require
       the  use  of a hostfile, or will default to running all X copies on the
       localhost), scheduling (by default) in a  round-robin  fashion  by  CPU
       slot.  See the rest of this page for more details.
