SRTF ALGORITHM

Shortest Remaining Time First (SRTF) Scheduling algorithm is a preemptive CPU scheduling method that selects the process with the shortest remaining burst time from the ready queue for execution. It is an extension of the Shortest Job First (SJF) algorithm, but with preemption. If a new process arrives with a shorter burst time than the one currently running, the CPU is preempted, and the shorter job is executed. This ensures that shorter jobs are given priority, leading to reduced average waiting times and improved system throughput. SRTF scheduling dynamically prioritizes processes based on their remaining burst times, allowing for efficient utilization of CPU resources. However, SRTF scheduling can suffer from the problem of starvation for longer processes if shorter ones keep arriving, as they might never get a chance to execute if shorter jobs continually arrive. To mitigate this, aging mechanisms can be implemented to increase the priority of older processes, ensuring fairness in resource allocation. SRTF scheduling is commonly used in time-sharing systems and environments where responsiveness and minimizing waiting times are crucial, such as interactive systems and real-time applications.
