Communicating Process Architectures
Communicating Process Architectures 2014,
the 36th. WoTUG conference on concurrent and parallel systems, takes place from
Sunday August 24th to Wednesday August 27th 2014 and is hosted by the
Department of Computer Science, University of Oxford.
Accommodation and evening Fringe sessions will be at
St. Anne's College,
a few minutes walk from the Department.
About WoTUG
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:
-
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, ...);
and to stimulate discussion and ideas on the roles concurrency will play in the future:
-
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.
Of course, neither of the above sets of bullets are exclusive.

Concurrent Event-driven Programming in occam-π for the Arduino
By Christian L. Jacobsen, Matthew C. Jadud, Omer Kilic, Adam T. Sampson
The success of the Arduino platform has made embedded programming widely
accessible. The Arduino has seen many uses, for example in rapid
prototyping, hobby projects, and in art installations. Arduino users are
often not experienced embedded programmers however, and writing correct
software for embedded devices can be challenging. This is especially
true if the software needs to use interrupts in order to interface with
attached devices. Insight and careful discipline are required to avoid
introducing race hazards when using interrupt routines. Instead of
programming the Arduino in C or C++ as is the custom, we propose using
occam-π as a language as that can help the user manage the concurrency
introduced when using interrupts and help in the creation of modular,
well-designed programs. This paper will introduce the Arduino, the
software that enables us to run occam-π on it, and a case study of an
environmental sensor used in an Environmental Science course.
