Abstract Interpretation-based Static Safety for Actors

Abstract

The actor model eases the definition of concurrent programs with non uniform behaviors. We present here an encoding of a higher-order actor calculus, CAP, into an abstract interpretation-based framework for the static analysis of mobile systems. Then, we prove that a CAP term and its encoding are bisimilar. Non-trivial properties are captured using existing abstract domains, as well as new ones such as our linearity abstract domain. As far as we know, it is one of the first analyzes that deals with behavioral and occurrence counting properties on a higher-order calculus.
