Contribution aux infrastructures de calcul global: délégation inter plates-formes, intégration de services standards et application à la physique des hautes énergies

Abstract : Computing resources powers today available, computers, data storage, network, open new working methods.
Centralized computers have been replaced by "client/server" distributed architectures which are in turn in competition with new distributed systems known as "peer to peer".
These new technologies are widely spread, and every body now uses them to send and receive emails, to buy and sell goods over the ebusiness or to exchange files, out of any infrastructure, from peer to peer.
Tradings, industrials and research workds have understand the new goals involved and massivly invest around these new technologies, named "grid". One of the fields is about calculating. This is the subject of the works presented here.

At the Paris South University, a synergy emerged between the Computing Science Laboratory (LRI) and the Linear Accelerator Laboratory (LAL) on grid infrasctructures, opening new investigations fields for the first and new high throuput computing for the other.
Works presented here are the results of this pluri disciplines collaboration. They are based on XtremWeb, the LRI global computing platform. We first introduce a state of the art of the large scale distributed systems, its principles, its architecture based on services. We then introduce XtremWeb and detail modifications and improvements we had to specify and implement to achieve our goals. We present two differents stydies to first interconnect grids in order to generalize resource sharings and to, then, be able to use legacy services on such platforms. We finally explain how a research community such as high energy science one can gain access to these services and detail monte carlos and data analysis processes over the grids.
