opal_wrapper - Back-end Open MPI wrapper command
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 http://www.openmpi.org/.
