%B Communicating Process Architectures 2009
%X In this work we motivate and describe three unique
   implementations of
processes for PyCSP: process, thread and
   greenlet based. The overall
purpose is to demonstrate the
   feasibility of Communicating Sequential
Processes as a
   framework for different application types and
   target
platforms.  The result is a set of three
   implementations of PyCSP with
identical interfaces to the
   point where a PyCSP developer need only
change which
   implementation is imported to switch to any of the
   other
implementations. The three implementations have
   different strengths;
processes favors parallel processing,
   threading portability and
greenlets favor many processes
   with frequent communication. The paper
includes examples of
   applications in all three categories.
