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:

#include <stdio.h>

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.
