  These are:</p>
<ul>
  <li>
    <p>Parallel for/DO </p>
  </li>
  <li>
    <p>Parallel sections </p>
  </li>
  <li>
    <p>The single directive </p>
  </li>
</ul>

<p>The constructs are placed inside an existing parallel region. The result is to distribute execution of associated statements among the existing threads. 
  No new threads are created. </p>

<p>Note that there is no implied synchronization of threads at the beginning of a work-sharing construct. For parallel sections and parallel for/DO, threads 
synchronize at the end of the construct by default. The following section provides more detail about the parallel for/DO construct.</p></body></html>
