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.

Linda implementation revisted
By Andrew Douglas, Alan Wood, Antony Rowstron
Linda is a model for communication and co-ordination of parallel processes. The model provides a virtual shared memory called tuple space, and primitives to place tuples into and remove tuples from tuple space. The style of programming provided by Linda is quite different to the style of, say, occam. We describe a new implementation of Linda across a network of transputers. We provide the four Linda primitives, in, out, rd and eval, together with a new primitive, collect, developed at York. The implementation focusses on two issues. The first issue is that the ordering of out operations in a sequential process must be preserved if we want Linda to act as a co-ordination language. Our implementation provides this. The second issue is the implementation of eval, Linda's mechanism for spawning processes. We outline an implementation which provides arbitrary spawning of processes which execute concurrently, despite the restriction, enforced by the transputer architecture, of declaring a static number of processes at compile time. We provide a small example to show how Linda can be used to write parallel programs, then outline current work being undertaken at York, which focusses on interpretive environments for high level parallel programming techniques. A prototype Linda implementation and ISETL interpreter have already been developed.
