<p class="MsoNormal">For static schedule the runtime does not track iterations. The __kmpc_for_static_init_4 (or similar, depending on the iteration variable type) is the only runtime call for a statically scheduled loop (not counting leading barrier if any).
After it compiler just loops over obtained range of iterations without involving runtime any more.<o:p></o:p></p>
