[Omp] Subroutines inside parallel block

[Patricia Bittencourt Sampaio]

  Hello,

     I'm trying to parallelize a block of code where a
call to a subroutine appears inside of it. However I
wonder what really happens when there is a dynamic
extension (a subroutine inside a parallel region). I
don't know if the subroutine is executed in parallel.
And , if does so, wich threads participate on the
execution of it? Perhaps as soon as entering at the
subroutine, another group of threads is created.
     Assuming the particular case where I have
something of this kind:

#pragma omp for
   for (i=0; i<n; i++)
   {
      sort();    
   }
      In this case, when each thread (let's to say 5
in total) invoque the sort routine, it's create
anouther group of threads so as to execute sort for
each one?

  I appreciate your help,
