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.

The Macramé 1024 Node Switching Network

By S. Haas, D. A. Thornley, M. Zhu, R. W. Dobinson, B. Martin

To date, practical experience in constructing switching networks using IEEE 1355 technology has been confined to relatively small systems and there are no experimental results on how the performance of such systems will scale up to several hundred or even several thousand nodes. Some theoretical studies have been carried out for large networks of up to one thousand nodes for different topologies. We present results obtained on a large modular testbed using 100 Mbits/s point to point DS links. One thousand nodes will be interconnected by a switching fabric based on the 32 way STC104 packet switch. The system has been designed and constructed in a modular way to allow a variety of different network topologies to be investigated (Clos, grid, torus, etc.). Network throughput and latency are being studied for various traffic conditions as a function of the topology and network size. Results obtained with the current 656 node setup are presented.
