http://article.sapub.org/10.5923.j.computer.20150503.02.html Highest response ratio next (HRRN) scheduling is a non-preemptive discipline. It was developed by Brinch Hansen as modification of shortest job next or shortest job first (SJN or SJF) to mitigate the problem of process starvation. In HRRN, the next job is not that with the shortest estimated run time, but that with the highest response ratio defined as This means, the jobs that have spent a long time waiting compete against those estimated to ha… news station greensboro nc

Web(a) HRRN has some overhead in tracking the remaining service time for each process in the ready queue. (b) HRRN may lead to process starvation if there are many short jobs. (c) HRRN adopts dynamic priorities, but it still favors the shorter jobs. (d) HRRN is a preemptive version of Shortest Job First (SJF) algorithm. (e) None of the above. WebApr 27, 2015 · HRRN is neat, because it tries to minimize the turnaround time average over all of the processes. After all, in a perfect system, all processes would have zero delay and a NTAT of 1.0.
