Necessary and Sufficient Conditions for Deterministic Desynchronization
Abstract
Synchronous reactive formalisms associate concurrent behaviors to precise schedules on global clock(s). This allows a non-ambiguous notion of "absent" signal, which can be reacted upon. But in desynchronized (distributed) implementations, absent values must be explicitely exchanged, unless behaviors were already provably independent and asynchronous (a property formerly introduced as endochrony). We provide further criteria restricting "reaction to absence" for correct desynchronization.
