OpenMP threads consists of a parallel region that forks a master thread into multiple child threads that each performs a function in parallel amongst each other and joins back to its parent thread after reaching the end of the parallel region.
<blockquote>
<p>#pragma omp construct [clause, ...]</p>
<p>structured block</p>
</blockquote>
The construct identifies what block of code is being executed in parallel and the clause qualifies the parallel construct. In comparison to the C++ 11 thread library, the threads are performed in a region while the C++ 11 thread library have to be specifically created and joined back to the parent thread.
