+Caution: [[BR]]
+To activate the OpenMP extensions for C/C++ and Fortran, the compile-time flag '''-fopenmp''' must be specified. This enables the OpenMP directive #pragma omp in C/C++ and !$omp directives in free form, c$omp, *$omp and !$omp directives in fixed form, !$ conditional compilation sentinels in free form and c$, *$ and !$ sentinels in fixed form, for Fortran. The flag also arranges for automatic linking of the OpenMP runtime library. [[BR]]
