Preemptive Shortest Job First Algorithm C Program

C Program To Implement Preemptive Shortest Job First Algorithm

Learn How To Implement Preemptive Shortest Job First Algorithm in C Programming. This C Program For SJF Algorithm using Arrival Time makes use of Arrays. The SJF Scheduling Algorithm is a Disk Scheduling Algorithm for processing various jobs entering the CPU. The SJF Scheduling Algorithm is also known as Shortest Process Next Scheduling Algorithm.


What is Preemptive Shortest Job Scheduling Algorithm?

The Shortest Job First Scheduling Algorithm executes the processes having the least burst time or execution time from the Ready Queue. The processes are, therefore, compared with each other and arranged based on their execution times. The processes which have the largest execution time executes at the last.

Since this SJF Scheduling Algorithm is a Preemptive Scheduling algorithm, the CPU can, therefore, leave a process and switch to another process. This technique, therefore, reduces the overall Response Time of the processes and increases the system performance.

    Why do we have to use Arrival Time in Preemptive Algorithm Code?

    Let there are 3 processes-1000,1001,1002
    Suppose at any point if two process have same burst time then it is broken by giving priority to the process with the lowest id no
    What will be the program for this?
