%X Message Passing Interface (MPI) is a popular approach to
   enable Single Process, Multiple Data (SPMD) style parallel
   computing, particularly in cluster computing environments.
   Communicating Process Architecture (CPA) Networking on the
   other hand, has been developed to enable channel
   based semantics across a communication mechanism in a
   transparent manner. However, in both cases the concept of a
   message passing infrastructure is fundamental. This paper
   compares the performance of both of these frameworks at a
   base communication level, also discussing some of
   the similarities between the two mechanisms. From the
   experiments, it can be seen that although MPI is a more
   mature technology, in many regards CPA Networking can
   perform comparably if the correct communication is used.
