If you wish to install MPI and OpenMP on your laptop/PC, we recommend the following:

• For OpenMP, the compile option -fopenmp is included automatically in recent versions of the C++ compiler and Fortran compilers. For users of different Linux distributions, siply use the available C++ or Fortran compilers and add the above compiler instructions, see also code examples below.
• For OS X users however, install libomp

  brew install libomp

and compile and link as

c++ -o <name executable> <name program.cpp>  -lomp
