+i.e. user-defined functors must not throw exceptions.
+Also, the order of execution is not guaranteed for some functions, of course.
+Therefore, user-defined functors should not have any concurrent side effects.
+</p><p> Since the current GCC OpenMP implementation does not support
+OpenMP parallel regions in concurrent threads,
+it is not possible to call parallel STL algorithm in
+concurrent threads, either.
+It might work with other compilers, though.</p></div><div class="navfooter"><hr /><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="parallel_mode.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="parallel_mode.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="bk01pt12ch31s03.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Chapter 31.
