9.Asynchronous message passing
•In asynchronous message passing,
processes communicate by sending messages through channels that can buffer the
messages.
•Kahn process network (PN) models and
dataflow models are variants of this techniques.
•PN models are excellent for signal
processing.
•Synchronous dataflow (SDF) is a
particularly restricted special case with the extremely useful property that
deadlock and boundedness are decidable.
