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.

View-Centric Reasoning for Linda and Tuple Space Computation

By Marc L. Smith, Rebecca J. Parsons, Charles E. Hughes

In contrast to sequential computation, concurrent computation gives rise to parallel events. Efforts to translate the history of concurrent computations into sequential event traces result in the potential uncertainty of the observed order of these events. Loosely coupled distributed systems complicate this uncertainty even further by introducing the element of multiple imperfect observers of these parallel events. Properties of such systems are difficult to reason about, and in some cases, attempts to prove safety or liveness lead to ambiguities. We present a survey of challenges of reasoning about properties of concurrent systems. We then propose a new approach, view-centric reasoning, that avoids the problem of translating concurrency into a se-quential representation. Finally. we demonstrate the usefulness of view-centric reasoning as a framework for disambiguating the meaning of tuple space predicate operations, versions of which exist commercially in IBM*s T Spaces and Sun*s JavaSpaces.
