Paper Detailsdb_connect: Could not connect to paper db at "wotug@dragon.kent.ac.uk"Repeatable execution of occam programs Authors: db_connect: Could not connect to paper db at "wotug@dragon.kent.ac.uk" Abstract: Parallel programs are intrinsically non-deterministic, and therefore the techniques of cyclical debugging that are commonly used for sequential programs are not suitable for parallel ones. This paper proposes a method for guaranteeing the repeatability of occam program behaviour. Saving information on the ALT guards selected at run-time allows program replay. i.e. makes it possible to re-execute the program following the same instruction path whatever the speed at which each component process is executed. This enables the software developer to use tools such as debuggers and intrusive monitors to help identify program errors. After a discussion on the possible implementations of the proposed technique, a prototype tools that allows the replat of occam programs within TDS is briefly described.
