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.

occwserv: An occam Web-Server
By Frederick R. M. Barnes
This paper presents ‘occwserv’, the occam web-server. This is a highlyconcurrent web-server, written in the occam multi-processing language, that supportsthe majority of the HTTP/1.1 protocol. Dynamic process and channel creation mechanismsare used to create scalable ‘server-farms’, each responsible for a particular webserverfunction - for example, reading client requests or running CGI processes. Thedesign of the web-server is presented, along with some early performance benchmarkresults. Although performance may appear a limiting factor (when compared to otherweb-servers such as Apache), much is gained from the simplicity and security of occam.Extending the web-server with new functionality, for example, is intuitive andlargely trivial - with the guarantees that code is free from race-hazard and aliasingerrors. An experimental non-standard addition, the OGI (occam Gateway Interface),is also presented. This provides a mechanism for dynamically loading and attachingpre-compiled occam processes to the running web-server, that can then handle oneor multiple client connections. A text-based style adventure game is examined briefly,that allows multiple clients to interact within a "multi-user dungeon" (MUD) styleenvironment.
