An EDF-based restricted-migration scheduling algorithm for multiprocessor soft real-time systems
There has been much recent interest in the use of the earliest-deadline-first (EDF) algorithm for scheduling soft real-time sporadic task systems on identical multiprocessors. In ...

Improved Tardiness Bounds for Global EDF
The Earliest Deadline First scheduling algorithm (EDF) is known to not be optimal under global scheduling on multiprocessor platforms. Results have been obtained that bound the ma...

Efficient Synchronization under Global EDF Scheduling on Multiprocessors
We consider coordinating accesses to shared data structures in multiprocessor real-time systems scheduled under preemptive global EDF. To our knowledge, prior work on global EDF h...

On the Implementation of Global Real-Time Schedulers
An empirical study of implementation tradeoffs (choice of ready queue implementation, quantum-driven vs. eventdriven scheduling, and interrupt handling strategy) affecting global ...
