WoTUG - The place for concurrent processes

Annual Conference: Communicating Process Architectures

Communicating Process Architectures 2017, the 39th. WoTUG conference on concurrent and parallel systems, takes place from Sunday August 20th. to Wednesday August 23rd. 2017 and is hosted by the Department of Computer Science at the University of Malta. Conference sessions will take place at the Auditorium of the University of Malta, Valletta Campus.

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.

A parallel semantic net engine and its application to data modeling

By Y. N. Lee

Although the use of Fourth Generation Languages has greatly increased the efficiency of the system development process, the validation of system specifications is still considered to be complicated and time-consuming. A "Parallel Semantic Net Engine (PSNE)" has been developed as part of a research project carried out in the Department of Computer Science at Exeter University to investigate into this area. This project was initiated by a software house, Softwright Systems Ltd., which has made extensive use of Fourth Generation Languages.The purpose of this project was to construct an engine which would be fast enough to validate a system specification in realtime, giving immediate feedback to the user when constraints are violated. The areas of knowledge representation and parallel processing were explored. A Parallel Semantic Net Engine was proposed in order to take advantage of the richness of semantic networks in representing complicated relationships and the power of transputers in speeding up the processing. Figure 1 shows the general model of the PSNE.The model is distributed over of a host PC and a network of transputers. On the PC side, there are the application generator, generated applications and a standard relational database which stores the application data. A front-end would be developed running on the PC to act as the gateway for data passing between the PC and the transputers.
