Multiprocessor and real-time scheduling
With a tightly coupled multiprocessor, multiple processors have access to the same main memory. In this configuration, the scheduling structure is somewhat more complex. For example, a given process may be assigned to the sane processor for its entire life, or it may be dispatched to any processor each time when it enters the running state. Performance studies suggest that the differences among various scheduling algorithms are less significant in a multiprocessor system.
A real-time process or task is one that is executed in connection with some process or function or set of events external to the computer system and that must meet one or more deadlines to interact effectively and correctly with the external environment. A real-time operating system is one that must manage real-time processes. In this context, the traditional criteria for choosing a scheduling algorithm do not apply. Rather, the key factor is the meeting of deadlines. Algorithms that rely heavily on preemption and on reacting to relative deadlines are appropriate in this context.

多处理器和实时多处理器调度紧耦合,多处理器可以访问相同的主存储器.在这种配置,调度结构较为复杂.例如,给定的进程可能被分配到理智的处理器的整个生命,也可能被分派到任何处理器每次当它进入运行状态.性能研究表明,不同的调度算法的多处理机系统各是那么重要了.一个实时进程或任务是执行一个在功能方面有一些过程或事件或系统设置外部的计算机,并且必须满足一个或多个期限,正确有效地互动与外部环境.一个实时操作系统是一个必须处理的实时进程.在这种情况下,对选择的调度算法的传统标准并不适用.相反,关键因素是会议的最后期限.算法依赖于抢占和反应相对严重的最后期限是在这方面适当的.
