8. Typing Actors using Behavioural Types

Typing Actors using Behavioural Types
Pages 51-55
J. Masini, A. Francalanza


The actor model of computation assists and disciplines the development of concurrent programs by forcing the software engineer to reason about high-level concurrency abstractions. While this leads to a better handling of concurrency-related issues, the model itself does not exclude erratic program behaviours. In this paper we consider the actor model and investigate a type-based static analysis
to identify actor systems which may behave erraticly during runtime. We consider the notion of behavioural types and consider issues related to the nature of the actor model including non-determinism, multi-party communication, dynamic actor spawning, non-finite computation and a possibly changing communication topology, which we contrast with existing works.
