title: Simple openmp call for loop not working
body: <p>I am writing some code that would definitively benefit from trying to integrate openmp some software that I am writing. I am new to openmp, and while testing some very basic test code (see below) I noticed that the execution times are extremely longer with openmp activated (#pragma line). Any insight is much appreciated. </p>
  
  <pre><code>int main()
  {
      int number=200;
      int max = 2000000;
  
      for(int t=1; t&lt;max; t++)
      {
          double fac = 0.0;
  
  #pragma omp parallel for reduction(+:fac)
          for(int n=2; n&lt;=number; n++)
              fac += 1;
      }
      return 0;
  }
  </code></pre>
