The behavior for the Sun-specific sunw_mp_sched_reserved schedule is the same as static with no chunk size.
If omp_set_max_active_levels()is called from within an active parallel region, then the call will be ignored. A warning message will be issued if SUNW_MP_WARN is set to TRUE or a callback function is registered by a call to sunw_mp_register_warn().
If the argument to omp_set_max_active_levels() is not a non-negative integer, then the call will be ignored. A warning message will be issued if SUNW_MP_WARN is set to TRUE or a callback function is registered by a call to sunw_mp_register_warn().
omp_get_max_active_levels() can be called from anywhere in the program. The call will return the value of the max-active-levels-var internal control variable.
