偶发实时的多处理机任务系统的可行性分析
Feasibility Analysis of Sporadic Real-Time Multiprocessor Task Systems
摘要:
我们给出了第一个算法,用于测试一组相同处理器上的零星实时的【形】任务的系统的可行性,解决了多处理器实时的【形】调度领域的一个主要开放问题[S.K. Baruah和K. Pruhs,Journal of Scheduling,2009]。我们还调查了相关的概念,可重复性和一个概念,我们称之为在线可行性。最后,我们表明,离散时间的时间表是强大的连续时间的时间表,这回答了另一个开放的问题,在上述调查。
英文摘要:
We give the first algorithm for testing the feasibility of a system of sporadic real-time tasks on a set of identical processors, solving one major open problem in the area of multiprocessor real-time scheduling [S.K. Baruah and K. Pruhs, Journal of Scheduling, 2009]. We also investigate the related notion of schedulability and a notion that we call online feasibility. Finally, we show that discrete-time schedules are as powerful as continuous-time schedules, which answers another open question in the above mentioned survey.
