title: changing thread number doesn't affect code
body: <p>I am trying to learn xeon-phi , and while studying the Intel Xeon-Phi Coprocessor HPC book , I tried to run the code <a href="http://pastebin.com/Fjwk74ie" rel="nofollow">here</a>. (from book)</p>
  
  <p>The code uses openmp and 2 threads.</p>
  
  <p>But the results I am taking are the same as running with 1 thread.
  ( no use of openmp at all )</p>
  
  <p>I even used in mic different combinations but still the same:</p>
  
  <pre><code>export OMP_NUM_THREADS=2
  export MIC_OMP_NUM_THREADS=124
  export MIC_ENV_PREFIX=MIC
  </code></pre>
  
  <p>It seems that somehow openmp is not enabled?Am I missing something here?</p>
  
  <p>The code using only 1 thread is <a href="http://pastebin.com/T8vEwjGW" rel="nofollow">here</a></p>
  
  <p>I compiled using:</p>
  
  <pre><code>icc -mmic -openmp -qopt-report -O3 hello.c
  </code></pre>
  
  <p>Thanks!</p>
