A major challenge in writing applications that execute across hosts, such as distributed online services, is to reconcile (a) parallelism (i.e., allowing components to execute independently on disjoint tasks), and (b)cooperation (i.e., allowing components to work together on common tasks). A good compromise between the two is vital to scalability, a core concern in distributed networked applications.

The actor model of computation is a widely promoted programming model for distributed applications, as actors can execute in individual threads (parallelism) across different hosts and interact via asynchronous message passing (collaboration). However, this makes it hard for programmers to reason about combinations of messages as opposed to individual messages, which is essential in many scenarios.

This paper presents a pragmatic variant of the actor model in which messages can be grouped into units that are executed in a serializable manner, whilst still retaining a high degree of parallelism. In short, our model is based on an orchestration of actors along a directed acyclic graph that supports efficient decentralized synchronization among actors based on their actual interaction. We present the implementation of this model, based on a dynamic DAG-inducing referencing discipline, in the actor-based programming language AEON. We argue serializability and the absence of deadlocks in our model, and demonstrate its scalability and usability through extensive evaluation and case studies of wide-ranging applications.
