FCFA: A semantic-based federated cloud framework architecture
No full textCloud Computing is a paradigm that applies a service model on infrastructures, platforms and software. In the last few years, this new idea has been showing its potentials and how, in the long run, it will affect Information Technology and the act of interfacing to computation and storage. This article introduces the FCFA project, a framework for an ontology-based resource life-cycle management and provisioning in a federated Cloud Computing infrastructure. Federated Clouds are presumably the first step toward a Cloud 2.0 scenario where different providers will be able to share their assets in order to create a free and open Cloud Computing marketplace. The contribution of this article is a redesign of a Cloud Computing infrastructure architecture from the ground-up, leveraging semantic web technologies and natively supporting a federated resource provisioning

A semantic-based federated cloud system for emergency response
No full textCloud federation can be described through the concept of collaboration, where each organization has its own cloud(s) that deals with a different and independent domain but needs to work together with other organizations in order to fulfill a specific shared objective. According to this perspective, the federation is a collection of interacting clouds that collaborate with one another through the instantiation and management of shared subsets of resources (computation and storage resources as well as sensors and actuators). This idea could be profitably used in those scenarios in which different organizations have to share several resources (e.g., emergency response or disaster management scenario). On the other hand, when different independent organizations share their resources, several issues arise. One of them is related to interoperability problems. As a consequence, this work also introduces a framework for an ontology-based resource life cycle management and provisioning in a federated cloud infrastructure. Therefore, The main contributions of this work consists of redesigning a cloud infrastructure architecture from the ground up, leveraging Semantic Web and Semantic Web Service Technologies, and natively supporting a federated provisioning of any kind of resource. This paper exploits, as a motivating scenario, a flood emergency response system
Advanced technologies and systems for collaboration and computer supported cooperative work
No full textThe recent developments in web technologies, pervasive and ubiquitous systems and networks, cloud and highly distributed computing systems, and the availability of massive amounts of data have changed the field of computer supported collaboration, particularly with the emergence of new capabilities and forms of collaboration both locally and remotely. These developments and capabilities present new challenges and issues as well. The purpose of this special issue on Advanced Technologies and Systems for Collaboration and Computer Supported Cooperative Work is to discuss cutting-edge research in the field of collaboration technologies and systems. The core contributions in this special issue are based on substantially extended versions of the most relevant manuscripts of the 2016 International Conference on Collaboration Technologies and Systems (CTS 2016). In this editorial, we also provide some observations from the last 10 years of CTS conferences in order to identify the major research areas covered by the papers that have been presented. The highlights and comments are presented in a chronological order and from a comparative perspective, along with a discussion of several research trends which may shape up the next decade in this important subject matter
High‐performance computing: to boldly go where no human has gone before
No full textInternational audienceComputing and computational science are well on their way to enter into the exascale era while High Performance Computing (HPC) is now present in many spheres and domains of modern society. New technologies such as cloud computing, big data, and connected objects open many perspectives and possibilities that were unattainable until now. These are high times for computing and for HPC in particular. The High Performance Computing \& Simulation conference aims to bring together researchers working on various aspects of HPC, their design and use, and their applications. As has been the conference tradition, selected extended papers of HPCS 2012 are presented in this special issue. These should be interesting contributions that supplement the current state-of-the-art research in HPC. To relate these works and highlight their value, in this article, we briefly trace back the history of HPC, sketch the state of the present research and development in the field, and project some of the challenges and future trends anticipated
Personalized Management of Semantic, Dynamic Data in Pervasive Systems: Context-ADDICT Revisited
No full textDue to the high information load to which everyone is exposed in her everyday life, the rise of new, systems fully supporting pervasive information distribution, analysis and sharing becomes a key factor to allow a correct and useful interaction among humans and omputer systems. This kind of systems must allow to manage, integrate, analyze, and possibly reason on, a
large and heterogeneous set of data.
The SuNDroPS system, briefly described in this paper, applies context-aware techniques to data gathering, shared services, and information distribution; the system is based on a context-aware approach that, applied to these tasks, leads to the reduction of the so-called information noise, delivering to the users only the portion of information that is useful in their current context
