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 Universität 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.

From Safe Concurrent Processes to Process-Classes? PLUSSING New Code by ROLLING out and Compile?

By Øyvind Teig

This article expands a concurrent language to support implementation inheritance by making block structures of the super process-class pluggable, and to interface inheritance by making the language's protocol inheritable. The parallel 'object-based' concurrent language occam 2 has been used as a catalyst for the concept, causing the language in fact to become (almost?) 'object-oriented' (OO). The result is white-box reuse between a 'process-class' and its sub process-class, and black-box reuse seen from the client side. Since occam is aliasing free and considered a 'safe' concurrent language, the expansion we discuss here keeps those properties - somewhat unusual for an OO system. This new language should be well suited in safety critical systems, since it has inherited the static (compile-time) and analysable properties from occam proper. Basically, two new keywords are defined: PLUSSING and ROLLING. The language feature suggestion is on sketch level only and therefore not complete, no BNF description exists and no compiler has been written.
