Hybrid-priority real-time scheduling
Sanjoy Baruah, Nathan Fisher · Proceedings - IEEE International Parallel and Distributed Processing Symposium · 2008
A hybrid scheduling algorithm is proposed, which integrates features of the fixed priority (FP) and earliest deadline first (EDF) scheduling policies. It is shown that this hybrid scheduling algorithm is a generalization of both FP and EDF, and tends to retain most of the desirable properties and features of both individual policies. Two exact (i.e., necessary and sufficient) tests are derived for sporadic task systems scheduled by the hybrid scheduling algorithm.
