28-29 Sept Active-object “workshop”

The 28 and 29 Sept the Scale team organises a small informal workshop on the current and future trends on active-objects, actor languages, and the verification tools for those languages. It will be in rooms Kahn 1 and Kahn 2. Everybody is welcome to attend and participate.

Program (preliminary)
!!! Each talk has a 45 minutes time-slot in order to leave plenty of time for discussions — Consequently, please plan on approx. 30 minutes of presentation; also please try to present your current and future works (at least in the conclusion of your talk) in order to trigger even more discussions.

In this thesis we address the formal specification, verification and deployment of distributed and reconfigurable GCM applications. Our first contribution is an industrial case study on the behavioural specification and verification of a reconfigurable distributed application: The HyperManager. This promotes the use of formal methods in an industrial context, but also puts in evidence the necessity for alternative and/or complementary approaches in order to better address such undertakings.

Our second contribution is a framework, developed with the Coq proof assistant, for reasoning on software architectures: Mefresa. This encompasses the mechanization of the GCM specification, and the means to reason about reconfigurable GCM architectures. Further, we address behavioural concerns by formalizing a semantics based on execution traces of synchronized transition systems. Overall, it provides the first steps towards a complete specification and verification platform addressing both architectural and behavioural properties.


Finally, our third contribution is a new Architecture Description Language (ADL), denominated Painless. Moreover, we discuss its proof-of-concept integration with ProActive — a Java middleware for concurrent and distributed programming, and the de facto reference implementation of the GCM. Painless allows to specify parametrized GCM architectures, along with their structural reconfigurations, in a declarative-like language. Compliance with the GCM specification is evaluated by certified functional code extracted from Mefresa. This permits the safe deployment and reconfiguration of GCM applications.

Cristian Ruz: Autonomic Components and Machine Learning, a couple of perspectives

Mercredi 26 Novembre 2014

In this talk I’ll present our last advances regarding implementation of autonomic behaviour in GCM components through an autonomic load balancer, in the context of the SCADA associate team ( Second, I’ll summarize some of the activities I’ve been involved in the context of the GRIMA research group ( and how autonomic components technology may help to process big sources of data as they are used for machine learning tasks.
