Annual Conference: Communicating Process Architectures
Communicating Process Architectures 2016,
the 38th. WoTUG conference on concurrent and parallel systems, takes place from
Sunday August 21st. to Wednesday August 24th. 2016 and is hosted by the
Niels Bohr Institute,
University of Copenhagen.
Conference sessions will take place at the
Hans Christian Ørsted Institute, which is located
The evening Fringe sessions will be at the
which is just
a few minutes walk from the Ørsted buildings.
WoTUG provides a forum for the discussion and promotion of concurrency ideas,
tools and products in computer science.
It organises specialist workshops and annual conferences that address
key concurrency issues at all levels of software and hardware granularity.
WoTUG aims to progress the leading state of the art in:
and to stimulate discussion and ideas on the roles concurrency will play in the future:
theory (programming models, process algebra, semantics, ...);
practice (multicore processors and run-times, clusters, clouds, libraries, languages, verification, model checking, ...);
education (at school, undergraduate and postgraduate levels, ...);
applications (complex systems, modelling, supercomputing, embedded systems, robotics, games, e-commerce, ...);
Of course, neither of the above sets of bullets are exclusive.
for the next generation of scalable computer infrastructure (hard and soft) and application,
where scaling means the ability to ramp up functionality (stay in control as complexity increases)
as well as physical metrics (such as absolute performance and response times);
for system integrity (dependability, security, safety, liveness, ...);
for making things simple.
A database of papers and presentations from WoTUG conferences is here.
The Abstract below has been randomly selected from this database.
A Comparison of Message Passing Interface and Communicating Process Architecture Networking Communication Performance
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.
