ABSTRACT:
A barrier is used to synchronize parallel processors. The barrier is "fuzzy", i.e. it includes several instructions in each instruction stream. None of the processors performing related tasks can execute an instruction after its respective fuzzy barrier until the others have finished the instruction immediately preceding their respective fuzzy barriers. Processors therefore spend less time waiting for each other. A state machine is used to keep track of synchronization states during the synchronization process.
