Aims

This course will provide a systematic treatment of concepts and issues in concurrency. The subject will be introduced via a small process algebra language, FSP, for specifying the concurrent behaviour of finite state processes. The Java language has built-in concurrency constructs and will be used to illustrate implementations of example specifications. Also the FSP language comes with software tools for animation and verification and these will be used in examples.

A wide variety of common concurrency problems will be investigated. Some of the underlying theory of the process algebra FSP and related algebras such as Milner's CCS and Hoare's CSP will be studied.

The course aims to:
Provide students with an understanding of concurrent systems, in particular how to model them using the process algebra FSP and how to implement them using Java.
Study techniques for the analysis of concurrent systems.
Introduce, via a set of case-studies, typical methods for solving concurrency problems.
Allow students to use a suite of tools for analysing FSP systems.
