“…Since 2010, ASP features multi-active objects [49] meaning that in each active object, several threads can run in parallel and process several requests of this active object, but each thread is still isolated inside a single activity. Such multi-active objects feature at the same time local concurrency and global parallelism.…”

International audienceTo program parallel systems efficiently and easily, a wide range of programming models have been proposed, each with different choices concerning synchronization and communication between parallel entities. Among them, the actor model is based on loosely coupled parallel entities that communicate by means of asynchronous messages and mailboxes. Some actor languages provide a strong integration with object-oriented concepts; these are often called active object languages. This paper reviews four major actor and active object languages and compares them according to carefully chosen dimensions that cover central aspects of the programming paradigms and their implementation

“…Still, the previous models are inefficient on multi-cores and can lead to deadlocks due to reentrant calls and/or inadequately placed release points. Newest active object models like multiactive objects [12] and Encore [5] feature controlled multi-threading. Such active object models succeed in maximising local parallelism while avoiding communication overhead, thanks to shared memory between the different threads [12].…”

“…The variable v stores an implicit future that is the result of a (transparent) asynchronous call. Recently, ProActive integrated multiactive objects [12] to enable multi-threaded request processing. Multiasp, presented in the next section, is an update of ASP and thus formalises the new version of ProActive.…”

Abstract. In the context of the expansion of actors and active objects, we are still facing a gap between the safety guaranteed by modelling and verification languages and the efficiency of distributed middlewares. In this paper, we reconcile two active object-based languages, ABS and ProActive, that respectively target the aforementioned goals. We compile ABS programs into ProActive, making possible to benefit from the strengths of both languages, while requiring no modification on the source code. After introducing the translational semantics, we establish the properties and the correctness of the translation. Overall, this paper presents an approach to running different active object models in distributed environments, and more generally studies the implementation of programming languages based on active objects.

SUMMARYComponent oriented software has become a useful tool to build larger and more complex systems by describing the application in terms of encapsulated, loosely-coupled entities called components. At the same time, asynchronous programming patterns allow for the development of efficient distributed applications. While several component models and frameworks have been proposed, most of them tightly integrate the component model with the middleware they run upon. This intertwining is generally implicit and not discussed, leading to entangled, hard to maintain code. This article describes our efforts in the development of the GCM/ProActive framework for providing distributed and adaptable autonomous components. GCM/ProActive integrates a component model designed for execution on large scale environments, with a programming model based on active objects allowing a high degree of distribution and concurrency. This new integrated model provides a more powerful development, composition, and execution environment than other distributed component frameworks. We illustrate that GCM/ProActive is particularly adapted to the programming of autonomic component systems, and to the integration into a service oriented environment.
