VORTEX 2018, ECOOP and ISSTA, Amsterdam, July 16-21, 2018


Runtime verification (RV) is an approach to software verification concerned with monitoring and analysis of software and hardware under execution. Recently, RV has gained more traction as an effective and promising approach to ensure software reliability, bridging a gap between formal verification and conventional testing; monitoring a system at runtime offers additional opportunities for addressing error recovery, self-adaptation, and other issues that go beyond software reliability. The goal of VORTEX is to bring together researchers working on runtime verification for topics covering either theoretical, or practical aspects, or, preferably, both, with emphasis on object-oriented languages, and systems.

Topics of interest include, but are not limited to, the following ones:

* behavioural types for RV
* combination of static and dynamic analyses
* industrial applications
* language support for RV
* monitor construction and synthesis techniques
* monitoring concurrent/distributed systems
* monitoring oriented programming
* program adaptation
* runtime enforcement, fault detection, recovery and repair
* RV for safety and security
* RV for the Internet of Things
* specification formalisms and formal underpinning of RV
* specification mining
* tool development

Contributions will be formally reviewed by at least three reviewers, and selection will be based on originality, relevance, technical accuracy, and the potential to generate interesting discussions.

With Ezio Bartocci (TU Wien, Austria), we will be chairing the track RV-TheToP: Runtime Verification from the Theory To the industry Practice.

Runtime verification. Runtime Verification (RV) has gained much focus, from both the research community and practitioners. Roughly speaking, RV combines a set of theories, techniques and tools aiming towards efficient analysis of systems’ executions and guaranteeing their correctness using monitoring techniques. Major challenges in RV include characterizing and formally expressing requirements that can be monitored, proposing intuitive and concise specification formalisms, and monitoring specifications efficiently (time and memory-wise).

With the major strides made in recent years, much effort is still needed to make RV an attractive and viable methodology for industrial use. In addition, further studies are needed to apply RV to wider application domains such as security, bio-health, power micro-grids and internet of things.

A Springer LNCS tutorial volume on advanced research topics is about to be re- leased by the organisers of the track. The book shall contain a selection of tutorials on advanced topics from leading researchers in the domain of runtime verification.

Description of the track. The purpose of the RV-TOP track at ISoLA’18 is to bring together experts on runtime verification and industry practitioners domains to i) have a dissemination of advanced research topics, ii) have a dissemination of current industrial challenges, and iii) get RV more attractive to industry and usable in additional applica- tion domains. As such, the track will contain three sorts of presentation:

– presentation of advanced tutorials from the authors involved in the Springer LNCS tutorial volume;

– presentation of current challenges in industry from industry practitioners;

– presentation of successful applications of RV to past industrial problems.

Today I’m at the defence of Matthieu Renard Ph.D. thesis in Bordeaux, France.

Matthieu’s thesis is entitled Runtime Enforcement of (Timed) Properties with Uncontrollable Events. 

This thesis studies the runtime enforcement of timed properties when some events are uncontrollable. This work falls in the domain of runtime verification, which includes all the techniques and tools based on or related to the monitoring of system executions with respect to requirement properties. These properties can be specified using different models such as logic formulae or automata. We consider timed regular properties, that can be represented by timed automata. As for runtime verification, a runtime enforcement mechanism watches the executions of a system, but instead of just outputting a verdict, it modifies the execution so that it satisfies the property. We are interested in runtime enforcement with uncontrollable events. An uncontrollable event is an event that an enforcement mechanism can not modify. We describe the synthesis of enforcement mechanisms, in both a functional and an operational way, that enforce some desired timed regular property. We define two equivalent enforcement mechanisms, the first one being simple, without considering complexity aspects, whereas the second one has a better time complexity thanks to the use of game theory; the latter being better suited for implementation. We also detail a tool that implements the second enforcement mechanism, as well as some performance considerations. The overhead introduced by the use of our tool seems low enough to be used in some real-time application scenarios.

I am at Konstantin Selyunin’s Ph.D. defense in Vienna, Austria.

Konstantin’s thesis is entitled Neural Models For Monitoring and Control with Applications in Automotive Domain.

The abstract of his thesis is below:

Cyber-physical systems (CPS), which incorporate physical as well as computational components, are a grand challenge of academia and industry in terms of their development, verification, and maintenance. In order for CPS to serve their purpose and ultimately make human lives safer, easier, more enjoyable, and convenient, both academia and industry needs to develop new methods for control and monitoring of such systems. Neural models are a very promising and far looking direction for the design of CPS controllers and monitors. In this thesis we first show how neural models can be applied in CPS control to quantify the uncertainty of the system. We then present how digital spiking neural model, called TrueNorth, can be used in the runtime monitoring of temporal-logic specifications for mission-critical systems. In order to be able to deliver not only a qualitative verdict, but also to reason in a quantitative way, we propose an approach for modeling arithmetic-functions with spiking neurones, and implement neural monitors for (signal) temporal logic specifications based on circular convolution.

In the applied part of the thesis we demonstrate how runtime monitoring can speed up the verification and validation phases in automotive electronic development. We identify phases where runtime monitoring can facilitate both pre- and post-silicon verification and testing. To build runtime monitors that are capable of keeping up with the speed of the physical sensors, we developed an approach to convert formalized requirements to hardware monitors, which are then synthesized in an FPGA. The results of this work enable long-term requirements evaluation and foster reuse of the monitors from pre- to post-silicon verification phases using high-level synthesis. We illustrate our approach by formalizing, creating hardware monitors, and evaluating the results in the lab environment for electrical and timing requirements of the industrial SENT and SPC protocols.

We will have a two-day meeting related to the COST Action Runtime Verification beyond Monitoring (ARVI). The purposes of the meeting include:

  • A meeting of the Management Committee (MC).
  • A workshop on contract monitoring.

The program of the meeting can be found here.

My roles during the meeting are twofold:

  • I am representing France in the MC.
  • I am co-chairing the working group related to core runtime verification.

Below is a description of the COST action:

Runtime verification (RV) is a computing analysis paradigm based on observing a system at runtime to check its expected behavior. RV has emerged in recent years as a practical application of formal verification, and a less ad-hoc approach to conventional testing by building monitors from formal specifications.
There is a great potential applicability of RV beyond software reliability, if one allows monitors to interact back with the observed system, and generalizes to new domains beyond computers programs (like hardware, devices, cloud computing and even human centric systems). Given the European leadership in computer based industries, novel applications of RV to these areas can have an enormous impact in terms of the new class of designs enabled and their reliability and cost effectiveness.
