Découverte automatique des caractéristiques et capacités d'une plate-forme de calcul distribué

Abstract : This thesis is devoted to the monitoring of modern computational platforms in order to obtain relevant, up to date and accurate information about them. Often called Grids, those environments differ from the preceding parallel machines by their intrinsic heterogeneity and high dynamicity.

This document is organized in three parts. The first one presents the specific difficulties introduced by this platform, highlighting them in a selection of grid infrastructure projects and detailing the existing solutions.

The second part shows how to get efficiently quantitative informations about the grid capacities and their suitability to the needs of the routines to schedule. After a discussion of the problems encountered, we detail our approach which we call macro-benchmarking. We then present FAST, a tool
implementing this methodology. We eventually detail how FAST is used in several other projects.

The third part introduces how to get a more qualitative view of the grid characteristics such as the topology of the network interconnecting the hosts. After a study of the existing solutions in this domain, we present ALNeM our solution to automatically map the network without relying on specific execution privileges on the platform. This tool is based on GRAS, our framework for the development of grid infrastructure.
