OpenMP is an implementation of Shared Memory parallelization. Information of how to run an existing OpenMP program can be found in the How_to_Use_OpenMP Section.
General
OpenMP programming is mainly done with pragmas:
int main(int argc, char* argv[])
{
#pragma omp parallel
printf("Hallo Welt!\n");
return 0;
}
interpreted by a normal compiler as comments, these will only come into effect when a specific compiler (options) is utilized like detailed here. Please check the more detailed tutorials in the References.
