Autonomous grids. Implementing national virtual organisations
نویسندگان
چکیده
The case is made for a more user-centric and hierarchical structure than is seen in the current large-scale computing grids in high energy physics. The ideas presented are backed by real-life study of use cases on the Swiss ATLAS grid prototype, covering 5 clusters at 3 academic institutions.

A Mobile Agent Strategy for Grid Interoperable Virtual Organisations
During the last few years much effort has been put into developing grid computing and proposing an open and interoperable framework for grid resources capable of defining a decentralized control setting. Such environments may define new rules and actions relating to internal Virtual Organisation (VO) members and therefore posing new challenges towards to an extended cooperation model of grids. ...
متن کاملRecognition of Authority in Virtual Organisations
A Virtual Organisation (VO) is a temporary alliance of autonomous, diverse, and geographically dispersed organisations, where the participants pool resources, information and knowledge in order to meet common objectives. This requires dynamic security policy management. We propose an authorisation policy management model called recognition of authority (ROA) which allows dynamically trusted aut...
متن کاملA federation-agent-workflow simulation framework for virtual organisation development
Traditional information system development approaches separate the domain model from the system model and then focus on the transformation between them. They are not, however, useful in rapid development of virtual organisations. This paper proposes a simulation-based development framework for establishing such organisations. It consists of a federation–agent– workflow (FAW) model, a set of rul...
متن کاملThe Multi-Disciplinary Development of Collaborative Grids: The Social Shaping of a Grid for Healthcare
Grid computing promises a range of industries the ability to distribute and share computing resources “on tap” and to provide transparent communication and collaboration between groups and across borders. Yet developing and implementing such complex and interrelated technology requires collaborative working among a range of disciplinary groups and organisations. Within this paper we present a c...
متن کاملImprove the Reactive Power Sharing by Uses to Modify Droop Characteristics in Autonomous Microgrids
Usually, the conventional droop methods is utilized for control of autonomous micro-grids. In islanded micro-grids (MG), due to the effects of mismatch in line impedance, the reactive power can't share by using the conventional droop method. In this paper, a method is proposed to improve reactive power sharing. In this method, the micro-sources are acted with P-w & Q-E droop characteristics, an...
