CPA-2005 last month was fun, and the paper I presented is now up on the CS publications database: Lazy Cellular Automata with Communicating Processes. The abstract:
Cellular automata (CAs) are good examples of systems in which large numbers of autonomous entities exhibit emergent behaviour. Using the occam-pi and JCSP communicating process systems, we show how to construct
lazyandjust-in-timemodels of cellular automata, which permit very efficient parallel simulation of sparse CA populations on shared-memory and distributed systems.
There's also Fred's Barrier synchronisation for occam-pi paper that I'm listed as a coauthor on, which is well worth a read.
