       opal_wrapper - Back-end Open MPI wrapper command


       opal_wrapper [options]


       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,  mpiCC,  mpic++,  and
       mpifort (and its legacy/deprecated names 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  names  mpif90.openmpi  and
       mpif77.openmpi),  mpicxx.openmpi,  mpiCC.openmpi,  mpicc.openmpi,  mpic++.openmpi, opalcc,
       opalc++, ortecc, and ortec++,


       The following may exist depending on your  particular  Open  MPI  installation:  mpicc(1),
       mpiCC(1),  mpic++(1), mpifort(1), mpifort.openmpi(1), mpicxx.openmpi(1), mpiCC.openmpi(1),
       mpicc.openmpi(1), mpic++.openmpi(1), ortecc(1), ortec++(1), opalccc(1), and the website at
