Annual Conference: Communicating Process Architectures
Communicating Process Architectures 2018,
the 40th. WoTUG conference on concurrent and parallel systems, takes place from
Sunday August 19th. to Wednesday August 22nd. 2018 and is hosted by
Professor Dr. Rainer Spallek,
Chair of
VLSI Design, Diagnostics and Architecture
at the Faculty of Computer Science,
Technische Universität Dresden, Germany.
The conference is organised by Dr. Spallek in collboration with Oliver Knodel and Uwe Mielke
and in partnership with WoTUG.
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.

The Development of occam: types, classes and sharing
By Geoff Barrett
The proposed extensions to the occam* language are aimed at providing • a more comprehensive type system• support for a modular programming style• a facility for sharing between processes.The type system is similar to that of many modern programming languages but with a careful treatment of union types and without recursive types.Although it is possible to describe shared objects in occam2, the required idiom has an implementation whose complexity is linear in the number of users. By introducing a special sort of shared bus of channels, this problem can be overcome.The class system is designed in such a way as to allow for separate compilation and alien code classes to be used in occam programs with little overhead and to provide some of the abstraction mechanisms which have been recognised as beneficial in object-oriented languages.There are also a number of new language features which do not significantly change the nature of the language but which do enhance its general expressiveness.The first part of this paper presents proposed changes to the occam2 reference manual ([1]). The second part is a commentary on the decisions which had to be made in order to produce the proposal. The section numbers of the manual changes correspond to the section numbers of the occam2 reference manual where a ' denotes a change to an existing section and a letter denotes the insertion of a new section.
