Deploiement d'ordonnanceurs de processus specifiques dans un systeme d'exploitation generaliste

Bossa is a framework to develop new processes schedulers in commodity operating systems. Although Bossa enables fine-grained management of the processor through new scheduling policies, deploying an application with its own scheduler raises some problems. In this paper we study the problems caused when deploying an application and its scheduler and to adresse these, we propose to establish Quality of Service contracts and mechanisms to reconfigure the scheduler hierarchy.
