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.

Shared-Clock Methodology for Time-Triggered Multi-Cores
By Keith F. Athaide, Michael J. Pont, Devaraj Ayavoo
The co-operative design methodology has significant advantages when
used in safety-related systems. Coupled with the time-triggered
architecture, the methodology can result in robust and predictable
systems. Nevertheless, use of a co-operative design methodology may
not always be appropriate especially when the system possesses tight
resource and cost constraints. Under relaxed constraints, it might be
possible to maintain a co-operative design by introducing additional
software processing cores to the same chip. The resultant multi-core
microcontroller then requires suitable design methodologies to
ensure that the advantages of time-triggered co-operative design are
maintained as far as possible. This paper explores the application of
a time-triggered distributed-systems protocol, called shared-clock ,
on an eight-core microcontroller. The cores are connected in a
mesh topology with no hardware broadcast capabilities and three
implementations of the shared-clock protocol are examined. The
custom multi-core system and the network interfaces used for
the study are also described. The network interfaces share higher
level serialising logic amongst channels, resulting in low hardware
overhead when increasing the number of channels.
