Automatic scheduling of applications with temporal QoS constraints: a case study

We have proposed a scheduling framework for the development and support of applications that must meet temporal Quality of Service (QoS) constraints. This paper develops a case study: a geostationary satellite application. We describe how the application threads are partitioned into finer grain (or elementary) threads to which QoS constraints are applied; how they are organized into dependency graphs; and how this decomposition as well as, the dependency information and QoS constraints required on the application are exploited by a cooperative scheduling system. We demonstrate this by presenting illustrative scheduling scenarios of the chosen application.
