    isbn 978-1-880843-75-8International audienceThe Agents in Grid project is devoted to the de-velopment of an agent-based intelligent high-level Grid middleware. In the proposed system, all data process-ing is ontology-driven, and initially was based on an in-house developed mini-ontology of the Grid. Our recent analysis has indicated that we should adapt and utilize the Grid ontology developed within the framework of the CoreGRID project. This note outlines how we have modified and extended the CoreGRID ontology to fulfill the needs of our approac

    Resource Management in Grids: Overview and a discussion of a possible approach for an Agent-Based Middleware

    14 pagesInternational audienceResource management and job scheduling are important research issues in computational grids. When software agents are used as resource managers and brokers in the Grid a number of additional issues and possible approaches materialize. The aim of this chapter is twofold. First, we discuss traditional job scheduling in grids, and when agents are utilized as grid middleware. Second, we use this as a context for discussion of how job scheduling can be done in the agent-based system under development

    Information Flow and Mirroring in an Agent-Based Grid Resource Brokering System

    International audienceThis work concerns part of our project, devoted to the development of an agent-team-based Grid resource brokering and management system. Here, open issues that have to be addressed in the process, concern agent team preservation. In our earlier work it was suggested that this can be achieved through mirroring of key information. Here, we discuss in detail sources of useful information generated in the system (an agent team in particular) and consider which information should be mirrored, when and where, to increase long-term sustainability of an agent team

    Scaling Campus Grids: Implementing a modified ontology based EMI-WMS on Campus Grids

    In an effort to deliver HPC services to the research community at the University of Huddersfield, many grid middle wares have been deployed in parallel to asses their effectiveness and efficiency along with their user friendliness. With a disparate community of researchers spanning but not limited to, 3D Art designers, Architects, Biologists, Chemists, Computer scientists, Criminologists, Engineers (Electrical and Mechanical) and Physicists, no single solution works well. As HPC is delivered as a centralised service, an ideal solution would be one that meets a majority of the needs, most of the time. The scenario is further complicated by the fact that the HPC service delivered at the University of Huddersfield comprises of several small high performance clusters, a high throughput computing service, several storage resources and a shared HPC services hosted off-site

    Abstract. We are developing an agent-team-based Grid resource brokering and management system. One of issues that has to be addressed is team preservation through mirroring of key information. We focused our attention on information generated within the agent team. In this paper we discuss sources of information generated in the system and consider which information should be mirrored to increase long-term survival of the team

    Ontology for Contract Negotiations in an Agent-based Grid Resource Management System

    International audienceOur research (the Agents in Grid; AiG project) concerns the development of an agent-based Grid middleware, in which (a) agents work in teams (each team is to be managed by the LMaster agent), (b) all meta-information is ontologically demarcated and semantically processed (with all team information stored in and managed by the Client Information Center; CIC infrastructure represented by the CIC agent), and (c) an economic model is to be based on autonomic Service Level Agreement (SLA) negotiations and Quality of Service (QoS) monitoring

    Negotiations in an Agent-based Grid Resource Brokering System

    International audienceThe aim of this chapter is to present an overview of issues concerning autonomous (possibly agent-based) \textit{Service Level Agreement} negotiations. To achieve this goal, first five European research projects are discussed that represent different approaches to the problem of integration of business and grid architectures, as well as various methods of establishing the SLA between grid users. Second, the experience gained from these projects is used as a foundation of conceptualization of the SLA negotiations in the AiG project
