The aim of the round-table is to investigate the opportunities and challenges of Pervasive Grids. The round-table brought together researchers from the Grid and Pervasive communities, who are active in the PG field, to discuss the definition of what is a PG. Is there a consensus on its applications and their requirements and challenges? Will a Pervasive Grid be eventually realized?
PG is motivated by the advances in Grid technologies and the proliferation of pervasive systems, and is leading to the emergence of a new generation of applications that use pervasive and ambient information as an integral part to manage, control, adapt and optimize. These include a range of application areas including crisis management, homeland security, personal healthcare, predicting and managing natural phenomenon, monitoring and managing engineering systems, optimizing business processes etc.
In his introduction, Jean-Marc Pierson mentionned also the problems of finding a killer application and the best ways to federate initiatives. From the other side, the challenges of the heterogenity, the dynamism, the large scale worlds lead to uncertainty on resources availability, on users, on tasks... pushing towards a world of autonomic entities coordinated by a global or a distributed mechanism? That is (one of) the question. Then Jean-Marc proposed a first list of keywords to characterize PG: Uncertainty, Dynamism, Context-awareness, Semantic/Knowledge, Closed-loop, Security, Adaptivity, Invisibility, Proactivity, Opportunistic (Ad-hoc), Self-*, Autonomic but collaboration among entities.
Lionel Brunie (INSA – Lyon – France) considered that autonomy is (very) nice but can also be very laborious if users have to take into account the data synchronization, the network administration, the data searching and processing, the data privacy, the data adaptation... He suggested that Grids should bring to the PG communauty the Grid Infrastructure (processing power, data integration, security issues...). In this case, he could dream of The Pervasive Grid: a kind of information Grid, user context-aware.
Geoffrey Coulson (Lancaster University, UK) focused on “Pervasive management support systems. For example: these are systems that are (i) driven by live sensor input from a sensor-actuator network; (ii) involve large-scale, real-time, grid-based computation (e.g. simulation or modelling) on the sensor input; and (iii) "close the loop" by driving the operation of the actuators in real-time. Geoff listed core challenges that interest him: SAN and adaptive local computation for instance.
In his talk, Minyi Guo (University of Aizu, Japan) insisted on the challenges of deep context awareness (makefull use of context information to take a decision and make use of commodity sensors), invisibility of resource management and discovery (use flexible smart space infrastruture to accommodate all kind of resource), cognitive continuity (due to user distraction, accommodate new computing utilities) and sentient software (make the software look smart some of the time in implementing some decent adaptive algorithms/heuristics).
Manish Parashar (Rudgers university – US) pointed out what he called “Pervasive Grid (Cyber) Ecosystems” which look like seamless, secure, on-demand access to and aggregation of geographically distributed computing with the good properties of Knowledge-based, information/data-driven, context/content-aware computationally intensive. In order to merit the name of Ecosystems, he “closed to loop” by saying that the systems needs also to acquire, analyse/predict and control itself based on a feedback between inputs and outputs. He suggested to provide autonomic control capabilities using actuation devices. A remark from the audience pointed out that the Ecosystem name is, maybe not apropriate because he considered that in an Ecosystem the resource are constant (for instance the volume of water on the earth is “constant”). In a PG system, we produce more and more data: the “assessment of energy is positive”.
Laurence T.Yang (Canada) among many interesting ideas introduced the particular concept of Pervasive Intelligence related to common knowledge. Then, the issues are the following: What knowledge is necessary for HP Cluster and smart u-things? What knowledge should be initially set? What knowledge can be added later on? What knowledge may be self-learned during uses? How knowledge is used for rich and varied real situations?
Amond the conclusions of the round table requesting for a medium to exchange information on the Pervasive Grid topic, we are pleased to announce that a WiKi has been started on: http://perse.insa-lyon.fr/pervasivegrids/
The round table ended by a questions and answers session. One question was about the standards that the Industry always requires to build/push a new technology. Maybe that we could start to build a PG by assembling current technologies as people have done with Desktop Grids based on PC and Ethernet networks in order to demonstrate the potential of one flavour of Grid Technology?
