This paper outlines a new language and run-time technology offering formalised design and effiecient implementation for highly concuurent dynamic systems. It is based on a careful combination of ideas from Hoare’s CSP (giving compositional semantics, refinement and safety/liveness analysis) and Milners’s pi-calculus (giving dynamic network construction and mobility). We have been experimenting with systems developing as layered networks of self-organising neighbourhood-aware communicating processes, with no need for advanced planning or centralised control. The work reported is part of our TUNA (‘Theories Undepinning Nanite Assemblies’) project, in parnership with colleagues from the Universities of York and Surry, which is investigating formal approaches to the capture of safe emergent behaviour in highly complex systems. A particular study modelling artificial blood platelets is described. The software technology scales to millions of processes per processor and distributes over common multiprocssor clusters.
