Modern society is increasingly dependent on critical infrastructure and on the services that it provides. The loss of one of these services may hit the public immediately in manners which are not always predictable. Furthermore, the amount of time that a given service is unavailable will affect other services through numerous direct and indirect dependencies, which are seldom considered. Natural or man-made disasters, and combinations of both, will have effects that are difficult or impossible to foresee without the appropriate tools. Due to the rapid progress in electronic communications and information technology, one would expect today’s crisis managers to have access to situational awareness and to the tools needed to inform their decisions. While much has been achieved for single-service operational headquarters like those of police, firefighting and ambulance services, there are no solutions that address the interactions and interdependencies of all critical functions and all critical infrastructure in a Public Protection and Disaster Response context. If a crisis develops when some aspect of critical infrastructure is partly or completely unavailable, crisis managers must make decisions using a very different framework compared to that used to handle limited incidents in normal times. Considering the difficulties resulting from the dependencies and interdependencies of critical infrastructure in normal times, making good decisions is becoming more and more difficult for crisis managers during a crisis. These challenges, combined with the enormous and possibly tragic consequences of suboptimal crisis management, provide good reasons to explore the subject. [less ▲]

European states regularly experience a wide range of major crisis events, including not only environmental disasters such as major flooding, avalanches and earthquakes, but also man-made incidents involving large-scale transport-related accidents and terrorist-sponsored events. When responding to such incidents, Emergency service agencies and rescue organisations are working together more frequently to enhance their overall operational effectiveness, often requiring collaboration across state borders. The REDIRNET project benefits multi-agency joint-working by facilitating information exchange through the concept of broad-scale data interoperability. [less ▲]

This paper discusses the use of social media for data interoperability and sharing between agencies during emergency situations, natural disasters, and disruptions of critical infrastructure. The work presented is ongoing in the context of the REDIRNET (Emergency Responders Data Interoperability Network) research project. The project’s purpose is to provide a decentralized framework for interoperability between emergency agencies’ systems, based on a public meta-data gateway controlled by the agencies through a socio-professional web interface. A major problem during crisis situations is sharing data from various sources between the agencies involved. These data are often heterogeneous and distributed between many organisations with different access rights, and may have little or no security level protection. This paper focuses on the shared platform, which collects information from a variety of sensor nodes and presents it in a user-friendly manner. [less ▲]

The High-Performance Linpack (HPL) benchmark is the ac- cepted standard for measuring the capacity of the world’s most powerful computers, which are ranked twice yearly in the Top 500 List. Since just a small deficit in performance can cost a computer several places, it is impor- tant to tune the benchmark to obtain the best possible result. However, the adjustment of HPL’s seventeen configuration parameters to obtain maximum performance is a time-consuming task that must be performed by hand. In a previous paper, we provided a preliminary study that proposed the tuning of HPL parameters by means of an Evolutionary Algorithm. The approach was validated on a small cluster hosted at the University of Luxembourg. In this article, we extend this initial work by describing Acbea, a fully-automatic benchmark tuning tool that performs both the configuration and installation of HPL followed by an automatic search for optimized parameters that will lead to the best benchmark results. Experiments have been conducted to validate this tool on several clusters, exploiting in particular the Grid’5000 infrastructure. [less ▲]
