Scheduling Soft Real-Time Jobs Over Dual Non-Real-Time Servers
In this paper, we consider soft real-time systems with redundant off-the-shelf processing components (e.g., CPU, disk, network), and show how applications can exploit the redundancy to improve the system's ability of meeting response time goals (soft deadlines). We consider two scheduling policies, one that evenly distributes load (Balance), and one that partitions load according to job slackne...
متن کاملDynamic Integrated Scheduling of Hard Real-Time, Soft Real-Time and Non-Real-Time Processes
Real-time systems are growing in complexity and realtime and soft real-time applications are becoming common in general-purpose computing environments. Thus, there is a growing need for scheduling solutions that simultaneously support processes with a variety of different timeliness constraints. Toward this goal we have developed the Resource Allocation/Dispatching (RAD) integrated scheduling m...
متن کاملReal-Time scheduling: from hard to soft real-time systems
Real-time systems are traditionally classified into hard real-time and soft real-time: in the first category we have safety critical real-time systems where missing a deadline can have catastrophic consequences, whereas in the second class we find systems for which we need to optimise the Quality of service provided to the user. However, the frontier between these two classes is thinner than on...
متن کاملA non-preemptive scheduling algorithm for soft real-time systems
1 Please direct all correspondence to Krishna Kavi, Department of Computer Science and Engineering, The University of North Texas, P.O. Box 311366, Denton, Texas 76203, [email protected] Abstract Real-time systems are often designed using preemptive scheduling and worst-case execution time estimates to guarantee the execution of high priority tasks. There is, however, an interest in exploring no...
متن کاملSoft Real-Time Scheduling on Multiprocessors
UMAMAHESWARI C. DEVI: Soft Real-Time Scheduling on Multiprocessors. (Under the direction of Prof. James H. Anderson.) The design of real-time systems is being impacted by two trends. First, tightly-coupled multiprocessor platforms are becoming quite common. This is evidenced by the availability of affordable symmetric shared-memory multiprocessors and the emergence of multicore architectures. S...
