Long-Term Scheduling Determines which programs are admitted to the system for processing 这取决于调度算法,如FCFS、短作业优先、基于优 先权、响应比高者优先等调度算法 How many programs are admitted to the system Controls the degree of multiprogramming When does the scheduler be invoked? Each time a iob terminates Processor is idle exceeds a certain thresholdLong-Term Scheduling • Determines which programs are admitted to the system for processing - 这取决于调度算法，如FCFS、短作业优先、基于优 先权、响应比高者优先等调度算法 • How many programs are admitted to the system ? - Controls the degree of multiprogramming • When does the scheduler be invoked? - Each time a job terminates - Processor is idle exceeds a certain threshold
