This problem appears in most Actor libraries where communication is mainly asynchronous, and where a synchronous call to other Actor would block the current Actor, precluding the processing of incoming ...
We propose here a novel parallel invocation abstraction that considerably simplifies the continuation complexity problem for distributed actor systems requiring non-blocking synchronous invocations. ...
Let us review these mechanisms in our Actor programming model. We provide several call abstractions in Actors: asynchronous calls, timed synchronous calls, parallel calls and pass by reference. ...

PAM allows the stepwise refinement of local parallelism within a system on a per-actor basis, without having to deal with low-level synchronization details and locks. ...
In order to combine scalability and ease of use, we propose Parallel Actor Monitors (PAMs), as a means to relax the sequentiality of intra-actor activity in a structured and controlled way. ...
Next to actor-based systems other related work deals with the coordination and synchronization of messages in object-oriented systems. ...

In this paper we introduce a new programming model of multi-threaded actors which feature the parallel processing of their messages. ...
In this model an actor consists of a group of active objects which share a message queue. ...
Other work of interest is to investigate into dynamic interfaces for the multi-threaded actors and programming abstractions for application-specific scheduling of multi-threaded actors. ...

In this paper, we discuss an implementation of a SOS model using actors in the object-oriented actor language ABS and how to argue that global properties about the model are inherited from the SOS level ...
Actor systems are distributed, asynchronously communicating units of computation with encapsulated state, with much weaker means of synchronizing between actors. ...
In contrast to work which studies compilation from one language to another, our work focuses on a specific model and its implementation and specifically targets parallel systems. ...
