Outil autonome de surveillance de grilles

ABSTRACT. Grids have become very complex. It makes the deployment and maintenance of systems a difficult task requiring lots of efforts from administrators. We believe that peer-to-peer overlay networks are a valuable basis to support some of the main issues of autonomic computing in the particular case of grids. This article presents the construction of an autonomous, decentralized, scalable, and efficient grid monitoring system. The components of this application negotiate through a peer-to-peer network to provide autonomic behaviors. Our solution is based on a gossip broadcast protocol upon a hierarchical, directed, and acyclic graph to rapidly diffuse information in the system while limiting the number of messages. The software architecture is detailed, and then the first results of its performance are presented and analyzed. MOTS-CLÉS : surveillance, calcul autonome, réseau pair-à-pair, protocole de bavardages.
