STUDY OF SCHEDULING ALGORITHMS AND THEIR IMPLEMENTATION IN LINUXscheduling algorithm in os
While real-time programs are explicitly recognized as such by the scheduling algorithm in Linux, there is no easy way todistinguish between interactive and batch programs.(need execute a while) Process Preemption As mentioned in the first chapter, Linux processes arepreemptable. When a process enter...
but does not limit the maximum distance. Instead, the algorithm remembers the directions and avoids selecting the directions that did not lead to a better solution until certain number of other attempts were made.

The Linux scheduling algorithm works by dividing the CPU time intoepochs. In a single epoch, every process has a specified time quantum whose duration is computed when the epoch begins. In general, different processes have different time quantum durations. The time quantum value is the maximum CP...
Round Robin scheduling is preemptive, which means that a running process can be interrupted by another process and sent to the ready queue even when it has not completed its entire execution in CPU. It is a preemptive version of First Come First Serve (FCFS) scheduling algorithm....

b. What is the algorithm that results from\alpha<\beta< 0? **答:**等同于LCFS Answer: First case is FCFS; second case is LIFO (last in, first out). 6.28 Assume that two tasks A and B are running on a Linux system. The nice values of A and B are −5 and +5, respectively....
