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.

Types, Orthogonality and Genericity: Some Tools for Communicating Process Architectures
By Samson Abramsky
We shall develop a simple and natural formalization of the idea
of client-server architectures, and, based on this, define
a notion of orthogonality between clients and servers,
which embodies strong correctness properties, and exposes the rich
logical structure inherent in such systems. Then we generalize
from pure clients and servers to components, which provide
some services to the environment, and require others from it.
We identify the key notion of composition of such components,
in which some of the services required by one component are supplied
by another. This allows complex systems to be built from ultimately
simple components. We show that this has the logical form of the
Cut rule, a fundamental principle of logic, and that it
can be enriched with a suitable notion of behavioural types
based on orthogonality, in such a way that correctness properties
are preserved by composition. We also develop the basic ideas of
how logical constructions can be used to develop structured
interfaces for systems, with operations corresponding to
logical rules. Finally, we show how the setting can be enhanced,
and made more robust and expressive, by using names (as in
the π-calculus) to allow clients to bind dynamically to generic
instances of services.
