Construction and Application of Representative Synthetic Workloads.

Abstract

OCESSING UNIT TIME, NUMBER OF I/O activities initiated, core used and the usage of unit record devices. These characteristics for each job are obtained from the system accounting data and are used to determine the characteristics of the drive workload by matching the joint probability distribution of the selected characteristics. The drive workload is realized by using a synthetic program that contains many parameters. Experiments were performed to calibrate the synthetic program. Equations are derived to relate the synthetic program parameters with the selected workload characteristics. By adjusting these parameters any desired combination of workload characteristics can be obtained. Using this procedure a synthetic workload with eighty-eight jobs is constructed to represent a month's workload consisting of about 6000 jobs. (Author)
