An Efficient Verifier of Truly Concurrent Properties (original) (raw)

1995

Abstract

We present a parametric tool for the analysis of distributed concurrent systems. Processes are internally represented as proved transition systems. Actually, we use a fragment of them, in which only one transition exits from a node among those mutually concurrent. This permits to have compact representations that are linear in average with the number of actions in the term of the language that describes the system. Another important property of these compact transition systems is that they preserve truly concurrent bisimulations, that can be checked in average in polynomial time. Parametricity is achieved by resorting to the rich labelling of the transitions encoding the parallel structure of processes. These labels are then “observed” for retrieving the interleaving, causal and locational semantics.
