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, ...);

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.

CCSP - A Portable CSP-Based Run-Time System Supporting C and occam

CCSP is a highly portable run-time system that conforms to the ideas of CSP and supports both the C and occam programming languages. Its aim is to further the use of the CSP mind-set in both industrial and academic applications. The run-time system implements a useful and efficient subset of the basic CSP constructs. It allows occam-style designs to be programmed in C, thereby allowing full use of the optimisation phases of standard C compilers. It supports the KRoC occam system for Linux/PC platforms. In addition, a number of features have emerged from industrial collaboration as essential for soft real-time systems in the real world. These include: prioritised scheduling with 32 priority levels, integration of communications hardware to provide support for distributed processing, and access to a highly accurate real-time clock. This paper discusses the high level structure and functionality of the features provided.
