The preemptive real-time scheduling of sporadic parallel task systems is studied. We present an algorithm, called Gang EDF, which applies the Earliest Deadline First (EDF) policy to the traditional Gang scheduling scheme. We also provide schedulability analysis of Gang EDF. Specifically, the total amount of interference that is necessary to cause a deadline miss is first identified. The contribution of each task to the interference is then bounded. Finally, verifying that the total amount of…

Analysis Techniques for Supporting Hard Real-Time Sporadic Gang Task Systems
TLDR
A novel approach combining new lag-based reasoning and executing/non-executing gang interval analysis technique is introduced, which is able to characterize the parallelisminduced idleness, as a key challenge of analyzing gang task schedules.
Optimal Scheduling of Periodic Gang Tasks
TLDR
The gang scheduling of parallel implicit-deadline periodic task systems upon identical multiprocessor platforms is considered and two DPFAIR (deadline partitioning) algorithms that schedule all jobs in every interval of time delimited by two subsequent deadlines are proposed.
Hard Real-Time Stationary GANG-Scheduling
TLDR
This paper provides the first schedulability analysis for sporadic constrained-deadline gang task systems and proposes a novel stationary gang scheduling algorithm that outperforms the state-of-the-art.
Virtual Gang Scheduling of Parallel Real-Time Tasks
TLDR
The novel concept of a virtual gang is introduced: a group of parallel tasks that are scheduled together as a single entity that transforms the original, complex scheduling problem into a form that can be easily implemented and is amenable to exact schedulability analysis, further reducing pessimism.

TLDR
A novel task model where each task is divided into a sequence of segments called bundles, each requiring a different number of cores, and the threads within each bundle are gang scheduled on an identical multiprocessor is introduced, which can significantly improve schedulability compared to the rigid model.
Gang FTP scheduling of periodic and parallel rigid real-time tasks
TLDR
This paper provides an exact schedulability test for Fixed Task Priority (FTP) Gang scheduler sub-classes: Parallelism Monotonic, Idling, Limited Gang, and Limited Slack Reclaiming and studies the predictability of the schedulers.
Partitioned scheduling of parallel real-time tasks on multiprocessor systems
TLDR
A partitioned scheduling algorithm is proposed which increases the laxity of the parallel segments and therefore the schedulability of tasksets of this model and eliminates the use of job migrations to create a portable algorithm that can be implemented on a standard Linux kernel.
Analysis of Federated and Global Scheduling for Parallel Real-Time Tasks
TLDR
The federated scheduling algorithm proposed in this paper is a generalization of partitioned scheduling to parallel tasks and shows that if on unit-speed cores, a task set has total utilization of at most m and the critical-path length of each task is smaller than its deadline, then Federated scheduling can schedule that task set.
On the Decomposition-Based Global EDF Scheduling of Parallel Real-Time Tasks
TLDR
This paper proposed a new decomposition strategy that better explores the feature of each task, represented by its structure characteristic value, to improve schedulability, and shows that this method consistently outperforms all of the previous methods under different parameter settings.
Conditionally Optimal Task Parallelization for Global EDF on Multi-core Systems
TLDR
This paper extends the interference-based sufficient schedulability analysis and derives monotonic increasing properties of both tolerance and interference for the Schedulability to propose a one-way search based conditionally optimal algorithm with polynomial time complexity.
