opal_wrapper is not meant to be called directly by end users. It is automatically invoked as the back-end
       by  the  Open MPI wrapper commands such as: mpicc, mpicxx, and mpifort (and its legacy/deprecated aliases
       mpif77 and mpif90).

       Some Open MPI installations may have  additional  wrapper  commands,  and/or  have  renamed  the  wrapper
       compilers  listed above to avoid executable name conflicts with other MPI implementations. Hence, you may
       also  have  wrapper  compilers  installed  including  the  following  names:  mpifort.openmpi  (and   the
       legacy/deprecated aliases mpif90.openmpi and mpif77.openmpi), mpicxx.openmpi, mpicc.openmpi.

       SEEALSO:
          The  following  may  exist  depending  on  your particular Open MPI installation: mpicc(1), mpicxx(1),
          mpifort(1)
