Convoy Effect in Operating System

Q.1: How the Convoy Effect can be reduced in Operating Systems?

Answer:

Preemptive scheduling techniques, like Round Robin Scheduling, can help prevent the Convoy Effect by minimizing the amount of time that smaller processes must wait for CPU time. As a result, they execute more quickly and use less idle resources.

Q.2: Does FCFS have the operating system’s Convoy Effect?

Answer:

If the burst time of the first work entering is the highest among all, First Come First Serve may suffer from the convoy effect. As is evident in real life, other people may be obstructed until the convoy passes completely if it is using the road. This also has an impact on the operating system.

Q.3: What is main difference between the Convoy effect and starvation?

Answer:

The Convoy effect causes slow down the operating system for a short period of time. although, starvation is the indefinite deferment of a process, that it is ready for allocation.



Convoy Effect in Operating Systems

The Convoy Effect is a phenomenon associated with the First Come First Serve (FCFS) algorithm, in which the whole Operating System slows down due to a few slow processes.

What is the Convoy Effect?

FCFS algorithm is non-preemptive in nature, that is, once CPU time has been allocated to a process, other processes can get CPU time only after the current process has finished. This property of FCFS scheduling leads to the situation called Convoy Effect. Suppose there is one CPU-intensive (large burst time) process in the ready queue, and several other processes with relatively fewer burst times but are Input/Output (I/O) bound (Need I/O operations frequently)....

Measures to Avoid the Convoy Effect in Operating System

Hence in Convoy Effect, one slow process slows down the performance of the entire set of processes, and leads to wastage of CPU time and other devices. To avoid Convoy Effect, preemptive scheduling algorithms like Round Robin Scheduling can be used – as the smaller processes don’t have to wait much for CPU time – making their execution faster and leading to less resources sitting idle....
