WoTUG - The place for concurrent processes

Communicating Process Architectures

Communicating Process Architectures 2014, the 36th. WoTUG conference on concurrent and parallel systems, takes place from Sunday August 24th to Wednesday August 27th 2014 and is hosted by the Department of Computer Science, University of Oxford. Accommodation and evening Fringe sessions will be at St. Anne's College, a few minutes walk from the Department.

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.

HW/SW Design Space Exploration on the Production Cell Setup

By Marcel A. Groothuis, Jan F. Broenink

This paper describes and compares five CSP based and two CSP related process-oriented motion control system implementations that are made for our Production Cell demonstration setup. Five implementations are software-based and two are FPGA hardware-based. All implementations were originally made with different purposes and investigating different areas of the design space for embedded control software resulting in an interesting comparison between approaches, tools and software and hardware implementations. Common for all implementations is the usage of a model-driven design method, a communicating process structure, the combination of discrete event and continuous time and that real-time behaviour is essential. This paper shows that many small decisions made during the design of all these embedded control software implementations influence our route through the design space for the same setup, resulting in seven different solutions with different key properties. None of the implementations is perfect, but they give us valuable information for future improvements of our design methods and tools.
