Abstract

Many different approaches have been attempted to the problem of controlling the processing of a multiprogramming computer system so as to improve performance. In Reference 1, Bowdon, et al. simulate an IBM 360/75 under OS with HASP and adjust job initiation priority based on estimates of processing time to effect a shortest-processing-time discipline. Their simulation demonstrates a dramatic increase in thruput and decrease in turnaround as a result of this job scheduling modification.
