Tardiness Bounds under Global EDF Scheduling on a Multiprocessor
We consider the scheduling of a sporadic real-time task system on an identical multiprocessor. Though Pfair algorithms are theoretically optimal for such task systems, in practice...

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...

A Stochastic Framework for Multiprocessor Soft Real-Time Scheduling
Prior work has shown that the global earliest-deadline-first (GEDF) scheduling algorithm ensures bounded deadline tardiness on multiprocessors with no utilization loss; therefore...

Integrating Job Parallelism in Real-Time Scheduling Theory
We investigate the global scheduling of sporadic, implicit deadline, real-time task systems on multiprocessor platforms. We provide a task model which integrates job parallelism. ...

Tardiness Bounds for FIFO Scheduling on Multiprocessors
FIFO scheduling is often considered to be inappropriate for scheduling workloads that are subject to timing constraints. However, FIFO is implemented in many generalpurpose OSs, a...
