Uneven memory regulation for scheduling IMA applications on multi-core platforms

The adoption of multi-cores for mixed-criticality systems has fueled research on techniques for providing scheduling isolation guarantees to applications of different criticalities. These are especially hard to provide in the presence of …


A parallel branch-and-bound algorithm to compute a tighter tardiness bound for preemptive global EDF

In this paper we present a parallel exact algorithm to compute an upper bound to tardiness of preemptive global EDF (G-EDF) schedulers, named harmonic bound, which has been proved to be up to 30% tighter than previously proposed bounds. Tightness …


Analysis techniques for supporting hard real-time sporadic gang task systems

This paper first studies the problem of scheduling hard real-time sporadic gang task systems under global earliest-deadline-first on a multiprocessor platform, where a gang application’s threads need to be concurrently scheduled on distinct …


Efficient offline scheduling of task-sets with complex constraints on large distributed time-triggered systems

Modern real-time applications like avionics and Internet-of-Things are required to aggregate more features and functionality with less production costs. Future applications like CityAirbus and autonomous driving require large distributed systems …

Many suspensions, many problems: a review of self-suspending tasks in real-time systems

In general computing systems, a job (process/task) may suspend itself whilst it is waiting for some activity to complete, e.g., an accelerator to return data. In real-time systems, such self-suspension can cause substantial …

Über diese Zeitschrift

The journal Real-Time Systems publishes papers, short papers and correspondence articles that concentrate on real-time computing principles and applications. The contents include research papers, invited papers, project reports and case studies, standards and corresponding proposals for general discussion, and a partitioned tutorial on real-time systems as a continuing series.

The range of coverage is broad, including requirements engineering, specification and verification techniques, design methods and tools, programming languages, operating systems, scheduling algorithms, architecture, hardware and interfacing, dependability and safety, distributed and other novel architectures, wired and wireless communications, wireless sensor systems, distributed databases, artificial intelligence techniques, expert systems, and application case studies.

Real-time systems find application in command and control systems, process control, flight control, avionics, defense systems, vision and robotics, pervasive and ubiquitous computing, and an abundance of embedded systems.
