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.

Combining EDF Scheduling with occam using the Toc Programming Language
By Martin Korsgaard, Sverre Hendseth
A special feature of the occam programming language is that its
concurrency support is at the very base of the language. However, its
ability to specify scheduling requirements is insufficient for use in
some real-time systems. Toc is an experimental programming language
that builds on occam, keeping occam's concurrency mechanisms, while
fundamentally changing its concept of time. In Toc, deadlines are
specified directly in code, replacing occam's priority constructs as
themethod for controlling scheduling. Processes are scheduled lazily,
in that code is not executed without an associated deadline. The
deadlines propagate through channel communications, which means
that a task blocked by a channel that is not ready will transfer
its deadline through the channel to the dependent task. This allows
the deadlines of dependent tasks to be inferred, and also creates
a scheduling effect similar to priority inheritance. A compiler and
run-time system has been implemented to demonstrate these principles.
