Large scale distributed systems like Grids are difficult to study only from theoretical models and simulators. Most Grids deployed at large scale are production platforms that are inappropriate research tools because of their limited re-configuration, control and monitoring capabilities. In this paper, we present Grid'5000, a 5000 CPUs nationwide(More)
Large scale distributed systems like Grid gather several characteristics making them difficult to study only from theoretical models and simulators. Most of Grid deployed at large scale are production platforms making them inappropriate research tools because of their limited reconfig-uration, control and monitoring capabilities. In this paper , we present(More)

GEYSERS aims at defining an end-to-end network architecture that offers a novel planning, provisioning and operational framework for optical network and IT infrastructure providers and operators. In this framework, physical infrastructure resources (network and IT) are dynamically partitioned to virtual resources and then composed into a Virtual(More)
The deployment of large scale grids generates new challenges in system and network monitoring. Users and distributed applications need to access logical and up to date information on sites reachability, links performances and services availability. In this paper, we propose a presentation model suitable for grid environments, and we present the tool(More)
A Grid Network monitoring and performance measurement infrastructure is a key component of a large-scale Grid. Requirements for network monitoring with respect to Grid operations as well as performance characteristics and their relevance to Grid context have to be carefully identified before realizing such a system. In this paper we analyze the main issues(More)
Data grid applications require often an access to infrastructures with high performance data movement facilities coordinated with computational resources. Other applications need interconnections of large scale instruments with HPC platforms. In these context, dynamic provisioning of customized computing and networking infrastructure as well as resource(More)
The Cloud Computing wave consolidates the on-demand provisioning of configurable virtual machines. Recent projects have proposed the extension of the original IaaS paradigm to provide dynamic virtual networks to interconnect virtual IT resources, composing Virtual Infrastructures (VIs). In this new scenario, users with different objectives and expectations(More)
