All modern computing systems incorporate some form of concurrency. Over many years, the WoTUG series of conferences has been a major forum for the presentation of state-of-the-art ideas on concurrency and communication. Communicating Process Architectures 2002 continues this trend, with these proceedings containing a number of high quality papers discussing a wide range of issues fundamental to the future of concurrency. This book combines papers from researchers and practitioners from many disciplines. Topics covered include theory, such as development to Hoare's Communicating Sequential Processes, hardware and real-time systems, software architecture and design, and applications.
