Rapport de recherche n˚5734 — Octobre 2005 — 10 pages Abstract: High availability (HA) is today an important issue in the domain of cluster computing, clusters being more and more larger, introducing a lot of failures. Today, the literature provides a lot of different HA strategies to tolerate application failures (applications being sequential or parallel). Unfortunately, it is still difficult to implement these HA policies inside a real system, and therefore the study of these policies is most of the time just theoretic, without real implementation. Therefore, a framework to ease the implementation of such policies is interesting. Moreover, a single system image (SSI), thanks to mechanisms for the global management of cluster resources, is a good candidate to provide such a framework. This paper presents the preliminary study of this framework on top of the Kerrighed SSI. Key-words: high availability, operating system, single system image (Résumé: tsvp
