4.10 Starvation and Aging in OS | CPU Scheduling Problems Explained Starvation in Operating Systems is a critical issue in CPU scheduling where certain processes wait indefinitely for CPU time despite being ready to execute. This commonly occurs in priority scheduling algorithms, where high priority processes are repeatedly selected while lower priority ones are ignored. Unlike deadlock, the system continues running, but some processes suffer from extremely high waiting time, making starvation a serious CPU scheduling problem that affects fairness and overall system performance. To solve starvation, Operating Systems use a technique called aging. Aging in OS gradually increases the priority of processes that have been waiting in the ready queue for a long time. This ensures that even low priority processes eventually get CPU time, preventing indefinite delays. By improving scheduling fairness, aging balances efficiency with responsiveness and is widely used in modern CPU scheduling algorithms. Understanding starvation and aging is essential for mastering CPU scheduling concepts in Operating Systems. While algorithms like Round Robin reduce starvation by giving each process a fixed time slice, priority scheduling and shortest job first can still face starvation if not managed properly. Modern OS designs, including multilevel queues and feedback queue scheduling, incorporate aging and hybrid strategies to ensure fairness, optimize waiting time, and improve overall system performance.
