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.

The denotational Semantics of View-Centric Reasoning

By Marc L. Smith, Charles E. Hughes, Kyle W. Burke

Both Lawrence’s HCSP [1] and Smith, et al’s VCR [2] (an earlier versionappears in [3]) extend CSP [4] with representations of truly concurrent events. Previously,VCR was described using an operational semantics, while the semantics ofHCSP’s Acceptances model, like those of the predominant CSP models described byRoscoe [5] (e.g., Traces, Failures / Divergences), are denotational. We now present adenotational semantics for VCRand, in so doing, propose an extension toHCSP (andpossibly other existing CSP models) to support View-Centric Reasoning. This workbrings VCR a step closer to being drawn within Hoare and He’s Unifying Theories ofProgramming [6] for further comparisons.
