Abstract
AbstractCoordination languages have emerged for the specification and implementation of interaction protocols among concurrent entities. Currently, we are developing a code generator for one such a language, based on the formalism of constraint automata (CA). As part of the compilation process, our tool computes the CA-specific synchronous product of a number of CA, each of which models a constituent of the protocol to generate code for. This ensures that implementations of those CA at run-time reach a consensus about their global behavior in every step. However, using the existing product operator on CA can be practically problematic. In this paper, we provide a solution by defining a new, local product operator on CA that avoids those problems. We then identify a sufficiently large class of CA for which using our new product instead of the existing one is semantics-preserving.KeywordsProduct OperatorLemma StateGlobal ConsensusLocal SynchronizationCoordination LanguageThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
