LITMUS^RT : A Testbed for Empirically Comparing Real-Time Multiprocessor Schedulers
TL;DR: This paper is the first attempt by anyone to compare partitioned and global real-time scheduling approaches using empirical data.
Proceedings ArticleDOI
An EDF-based scheduling algorithm for multiprocessor soft real-time systems
TL;DR: This paper proposes a new EDF-based scheme that ensures bounded deadline tardiness, which should enable a wide range of soft real-time applications to be scheduled with no constraints on total utilization.
Proceedings ArticleDOI
Real-Time Scheduling on Multicore Platforms
TL;DR: A cache-aware Pfair-based scheduling scheme for real-time tasks on multicore platforms that avoids co-executing applications or threads that can worsen the performance of shared caches and thrash them is proposed and evaluated.
Journal ArticleDOI
Tardiness bounds under global EDF scheduling on a multiprocessor
TL;DR: This paper derives tardiness bounds under preemptive and non-preemptive global EDF when the total system utilization is not restricted, except that it not exceed the available processing capacity, so processor utilization can be improved for soft real-time systems on multiprocessors.
Proceedings ArticleDOI
Tardiness bounds under global EDF scheduling on a multiprocessor
TL;DR: It is noted that global EDF may be superior to partitioned EDF for multiprocessor-based soft real-time systems in that the latter does not offer any scope to improve system utilization even if bounded tardiness can be tolerated.
