An Improved Schedulability Test for Uniprocessor Periodic Task Systems

چکیده

We present a sufficient linear-time schedulability test for preemptable, asynchronous, periodic task systems with arbitrary relative deadlines, scheduled on a uniprocessor by an optimal scheduling algorithm. We show analytically and empirically that this test is more accurate than the commonlyused density condition. We also present and discuss the results of experiments that compare the accuracy and execution time of our test with that of a pseudo-polynomial-time schedulability test presented previously for a restricted class of task systems in which utilization is strictly less than one.

Near-Optimal Bandwidth Allocation for Fixed-Priority Scheduled Arbitrary-Deadline Sporadic Tasks upon Periodic Resources∗

Schedulability for compositional real-time systems has been the focus of a great deal of recent research. In this problem domain, we consider the fixed-priority (FP) scheduling of arbitrary-deadline sporadic task systems upon periodic resources. Existing exact or approximate schedulability tests for dedicated uniprocessor scheduling can be used in this setting by modeling the “no-supply period”...

Exact schedulability tests for real-time scheduling of periodic tasks on unrelated multiprocessor platforms

In this paper, we study the global scheduling of periodic task systems on unrelated multiprocessor platforms. We first show two general properties which are well known for uniprocessor platforms and which are also true for unrelated multiprocessor platforms: (i) under few and not so restrictive assumptions, we prove that feasible schedules of periodic task systems are periodic starting from som...

Sustainability in Real-time Scheduling

A scheduling policy or a schedulability test is defined to be sustainable if any task system determined to be schedulable remains so if it behaves ‘‘better’’ than mandated by its system specifications. We provide a formal definition of sustainability, and subject the concept to systematic analysis in the context of the uniprocessor scheduling of periodic and sporadic task systems. We argue that...

Schedulability Test for Soft Real-Time Systems under Multiprocessor Environment by using an Earliest Deadline First Scheduling Algorithm

This paper deals with the study of Earliest Deadline First (EDF) which is an optimal scheduling algorithm for uniprocessor real time systems use for scheduling the periodic task in soft real-time multiprocessor systems. In hard real-time systems, a significant disparity exists EDF-based schemes and RMA scheduling (which is the only known way of optimally scheduling recurrent real-time tasks on ...

kU: A General Framework from k-Point Effective Schedulability Analysis to Utilization-Based Tests

To deal with a large variety of workloads in different application domains in real-time embedded systems, a number of expressive task models have been developed. For each individual task model, researchers tend to develop different types of techniques for deriving schedulability tests with different computation complexity and performance. In this paper, we present a general schedulability analy...
