Abstract

To facilitate the construction of concurrent programs based on progress requirements, we study an integration of the Owicki/Gries theory with UNITY's leads-to relation. In particular we investigate a set of calculational rules for leads-to, and we study the composition of programs regarding their effect on progress. Apart from parallel composition, we consider the less familiar notion of weak sequential composition. Our techniques are illustrated on two network initialisation protocols that are related to the protocol standard IEEE 1394.
