Communicating Process Architectures

The CPA 2011 proceedings are available from IOS Press; in addition, all papers and presentations from the conference can be found in the WoTUG paper database.

We are currently planning CPA 2012 — watch this space!

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.

Supercomputing Resource Management - Experience with the SGI Cray Origin 2000

The Oxford Supercomputing Centre OSC was established in April 1998 to provide high-performance computing services to a consortium of Oxford University research groups. The main computer resource, an 84-processor SGI Cray Origin 2000 known as Oscar, is being deployed in a wide variety of research studies covering biological, medical, chemical, mathematical, physical and engineering topics (including parallel computing itself). In this paper we shall describe the queueing and accounting mechanisms we have developed to facilitate effective use of this powerful resource. We shall also describe innovative work in progress to optimise the performance of this machine, using simulation and genetic algorithms.
