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

TL;DR

This paper introduces Bossa, a framework for developing custom process schedulers in general-purpose operating systems, addressing deployment challenges through QoS contracts and scheduler reconfiguration mechanisms.

Contribution

It proposes solutions for deploying custom schedulers in commodity OSes by establishing QoS contracts and enabling scheduler hierarchy reconfiguration.

Findings

Bossa facilitates the development of custom schedulers.

QoS contracts help manage deployment issues.

Reconfiguration mechanisms improve scheduler flexibility.

Abstract

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.
