Gestion de ressources pour des services déportés sur des grappes d'ordinateurs avec qualité de service garantie

Abstract : Tasks scheduling on clusters for remote services with quality of service. Many high performance applications require lots of resources. Environment like clusters or grid is interesting for their execution. This thesis studies parallel or sequential applications on clusters with precise management of resources in order to define a level of quality of service. It deals with execution support model, applications needs expression and scheduling. Two approachs are proposed : one in a deterministic mode where every application running on a host is known and controled and the other one in a stochastic mode where some part of the load of the host is unknown. Every application belongs to one of the four classes of quality of service defined which determines the level of quality of service requested. Scheduling algorithms are proposed on clusters which guarantee quality of service. They are based on events simulation and differential equations deducted from markovian models. An extension of the algorithm on the grid level is presented. Applications are represented by a graph of communicating tasks. Algorithms are validated by simulation and are integrated in a resources manager (AROMA : scAlable Resources Manager and wAtcher). A model to invoice a client for the used resources is proposed.
