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.

A Versatile Hardware-Software Platform for In-Situ Monitoring Systems

By Bernhard H.C. Sputh, Oliver Faust, Alastair R. Allen

In-Situ Monitoring systems measure and relay environmental parameters. From a system design perspective such devices represent one node in a network. This paper aims to extend the networking idea from the system level towards the design level. We describe In-Situ Monitoring systems as network of components. In the proposed design these components can be implemented in either hardware or software. Therefore, we need a versatile hardware-software platform to accommodate the particular requirements of a wide range of In-Situ Monitoring systems. The ideal testing ground for such a versatile hardware-software platform are FPGAs (Field Programmable Gate Arrays) with embedded CPUs. The CPUs execute software processes which represent software components. The FPGA part can be used to implement hardware components in the form of hardware processes and it can be used to interface to other hardware components external to the processor. In effect this setup constitutes a network of communicating sequential processes within a chip. This paper presents a design flow based on the theory of CSP. The idea behind this design flow is to have a CSP model which is turned into a network of hardware and software components. With the proposed design flow we have extended the networking aspect of sensor networks towards the system design level. This allows us to treat In-Situ Measurement systems as sub-networks within a sensor network. Furthermore, the CSP based approach provides abstract models of the functionality which can be tested. This yields more reliable system designs.
