There is  fairly major technical issue with this suggestion. On Mac we 
don't have a C++ OpenMP (OpenMPI is a different tool for message 
passing) implementation available. To get the current Fortran OpenMP 
code working on Mac we have had to take some liberties with mixing 
gfortran OpenMP code with C & C++ code compiled with Apple clang & 
clang++ which have no OpenMP support. We must use Apple clang++ on Mac 
since that is the only fully supported C++ compiler with Qt on that 
platform.

I would strongly suggest using threading probably supported by the Qt 
framework if we wish to obtain parallelism in our C++ code.
