 Barrier (uint32_t num_thread)
 Barrier (const Barrier &)=delete
Barrieroperator= (const Barrier &)=delete
void arrive_and_wait ()
 increment the arrived count and release the barrier if count matches number of threads to arrive otherwise wait for the arrived count to match the number of threads to arrive
void arrive_and_drop ()
 increment the arrived count and release the barrier if count matches number of threads to arrive, return immediately without waiting for release condition
