in real time operating systems to control software tasks. But in some situations there is a need for scheduling algorithms in real time systems. This need arises especially when time-critical software tasks need to run at different working periods and on a specific timeline. Different scheduling ...
feasible:调度算法是feasible,表示没有overflow发生,即任务的服务质量都得到了满足 response time:响应时间和请求时间间的时间间隔 a critical instant:该时刻,任务的response time将会最大 a critical time zone:任务在critical time时的response time 定理1如果任务请求时,所有优先级更高的任务也发生请求,该时刻为任务...
刘教授是计算机实时系统领域的开山祖师,他在1973年发表的论文Scheduling Algorithms for Multiprogramming in a Hard-Real-Time Environment可以称得上开天辟地,他在这篇论文中提出了著名的Liu&Layland上限,这一理论也成为了计算机实时系统设计的基本准则。许多实时系统中的问题都来源于此,例如多核处理器出现之后,实时系统从...
Scheduling algorithms differ in their criterion in determining when, and for how long, a task can execute on a processor. Real-time scheduling algorithms exist to ensure that regardless of system load—or the amount of threads eligible to be dispatched—the time-critical tasks of the system get...

schedules when there is provision for fault-tolerance. The performance of the solutions proposed is evaluated in terms of the number of processors and the cost of the checkpoints needed. Moreover, analytical studies are used to reveal interesting trade-offs associated with the scheduling algorithms....
