Usually is the seriell compilation with g++ and the parallel with mpiCC. Has anybody done a program like this before???
mpiCC is a wrap to g++ that adds flags to find MPI include and library files. You can compile both with mpiCC. To run the serial version, you can call the binary directly and to run the parallel version run your program through mpirun to run inside the MPI enveronment.
