Abstract

We discuss the usefulness of group-based abstractions for the modeling of distributed applications. We suggest that groups can be considered at a higher level of abstraction, and group concepts can be supported as distributed programming constructs in high-level models and languages. We illustrate this approach by discussing GroupLog, an abstract model that uses groups to specify a structured space of interactions, and the collective behavior of cooperating group members.
