چکیده

Earliest deadline first (edf) is a widely used algorithm for online deadline scheduling. It has been known for long that edf is optimal for scheduling an underloaded, single-processor system; recent results on the extra-resource analysis of edf further revealed that edf when using moderately faster processors can achieve optimal performance in the underloaded, multi-processor setting. This paper initiates the extra-resource analysis of edf for overloaded systems, showing that edf supplemented with a simple form of admission control can provide a similar performance guarantee in both the single and multi-processor settings.

Value Based Overload Handling of Aperiodic Tasks in Offline Scheduled Real-Time Systems

This paper describes a runtime scheduling method for a mix of off-line scheduled and value based dynamic tasks with a focus on overload situations. We present a formulation of overload handling as a general binary optimisation problem and give an algorithm for solving it. Our method is based on slot shifting [4] to provide for the integration of offline and online scheduling. Dynamic tasks are ...

Value vs. Deadline Scheduling in Overload Conditions

In this paper we present a comparative study among scheduling algorithms which use different priority assignments and different guarantee mechanisms to improve the performance of a real-time system during overload conditions. In order to enhance the quality of service, we assume that tasks are characterized not only by a deadline, but also by an importance value. The performance of the scheduli...

High Utilization Guarantee for Hierarchical Diff-EDF Schedulers

Packet networks are currently enabling the integration of traffic with a wide range of characteristics that extend from video traffic with stringent QoS requirements to the best-effort traffic requiring no guarantees. QoS guarantees can be provided in conventional packet networks by the use of proper packet scheduling algorithms. As a computer revolution, many scheduling algorithms have been pr...

A Real-Time Scheduling Algorithm for Soft Periodic Tasks

Since now, some scheduling algorithms have been presented to guarantee the time constraints of soft real-time tasks, but most of them have some drawbacks. The first drawback of them is that scheduling decisions are based on parameters which are assumed to be crisp; however, in many environments the values of these parameters are uncertain. The second one is the high time complexity of these met...

Matrix-DBP For (m, k)-firm Real-Time Guarantee

1 (m, k)-firm means at least m deadlines should be met among any k consecutive task invocations or message transmissions. Providing (m, k)-firm guarantee is becoming attractive as it proposes an alternative between hard real-time guarantee (case of m = k) and soft (or probabilistic) real-time guarantee with p = m/k (when m, k → ∞) and allows more effective utilization of server resources (proce...
