A Deadlock Detection Tool for Occam

Authors: Joosen, Wouter, Verbaeten, Pierre


A problem that occurs frequently during the development of parallel programs is deadlock.In the domain of transputer technology (and of parallel computing in general) run time debugging software still is a problem. This increases the value of verification tools based on static analysis, even if the functionality is sometimes limited.In this paper we present our approach to static analysis. The analyzer reduces an occam program to the relevant actions hi the context of this problem (communication, possibly through guards: PAR constructions...), and subsequently examines the program, reporting possible problems that could occur during real execution. The tool goes beyond the purpose of detecting deadlocks only: other infinite wait situations are also reported.
