Abstract: A new synchronization system synchronizes data exchanges between producer processes and consumer processes which may be on the same or different processors in a multiprocessor system. The synchronization incurs less than one roundtrip of latency - in some implementations, in approximately 0.5 roundtrip times. A key aspect of the fast synchronization is that the producer’s data store is followed without delay with the updating of a barrier on which the consumer is waiting.
