ABSTRACT

In the federated approach to multiprocessor scheduling, a task is either restricted to execute upon a single processor (as in partitioned scheduling), or has exclusive access to any processor upon which it may execute. Earlier studies concerning the federated scheduling of task systems represented using the sporadic DAG model were restricted to implicit-deadline task systems; the research reported here extends this study to the consideration of task systems represented using the more general constrained-deadline sporadic DAG model.
