Parallel Processing
In parallel processing systems, many events may be considered and acted
upon simultaneously. Since a variety of actions may be considered
simultaneously,
coherence in behavior is an
issue for parallel systems. A parallel system may be synchronous, in
which there is an explicit parallel decision cycle or
asynchronous. In asynchronous systems, there are usually a set of
independent components which act autonomously to one another; this
makes coherence an even more difficult problem.
A parallel architecture
does not necessarily imply
parallel processing; for instance,
the
human cognitive architecture is
inherently serial at the
cognitive level even though
the biological band is
explicitly parallel. However, there may tremendous improvements to
efficiency for some parallel
processing strategies, compared to
serial ones.
The following systems use some parallel techniques in their
implementation:
