<br>
As LLVM's OpenMP uses Intel's runtime library now, it re-uses threads when possible.<br>
<br>
There could be introduced execution modes that require to destroy threads after each<br>
parallel region in future OpenMP standards, but currently OpenMP threads<br>
are created once for the lifetime of the application with no ability to destroy them.<br>
<br>
And I'd guess that any OpenMP implementation behaves same way.<o:p></o:p></p>
