I suppose you may mean kmp_hyper_barrier_release
This is an Intel OpenMP function, so you should be able to find out which OpenMP parallel region is involved, and perhaps whether it may be diagnosed as work imbalance, by running against the profiling copy of the library, and checking the guide.gvs file which should be written at successful completion.
