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.

Copying, Moving and Borrowing Semantics

In this paper we discuss primitives for mobilising code and communications. We distinguish three types of semantics for mobility: copying (where an identical copy is created remotely), moving (where the original is destroyed), and borrowing (where the original is moved to the target and back to where it came from at defined moments). We discuss these semantics for mobile code and mobile channels. We have implemented Icarus, a language that uses borrowing semantics for mobile code (the on-statement) and moving semantics for mobile channels (first class channels).
