WoTUG - The place for concurrent processes

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 Universit├Ąt 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.

A Scalable Communication Network for a Parallel Database Machine

By David Walter, Jon Kerridge

The IDIOMS parallel database machine has at its kernel a scalable communications structure. The scalability is fundamental to the database machine because it is intended that the parts which are joined together by the communications network can be added to as demands on the database machine change. The network must be scalable both in terms og the number of user processes which can be supported, and, in order to meet the performance requirements of large systems, it should be possible to scale up the bandwidth of the network by adding further communication processors. The structure of a node in the network is described in terms of itsccam behavior which shows how node control is achieved by a control process that manipulates a set of flags by means of channel communications. The network is shown to be free from the possibility of deadlock. Finally, the performance and operational characteristics of the network are discussed and it is shown that the network is ideally suited for parallel database operation.
