Improving TSS/360 Performance by Tuning the Table-Driven Scheduler.

Abstract

During the period of time from August 1970 through January 1971 and while employing the TSS/360 Time-Sharing System at this institution, it was observed by the user community that the performance of the system was poor compared to the previously used time-sharing system - the CP/67 (version 3, from Cambridge Research Center). For this reason, the problem of improving TSS/360 performance was undertaken as a thesis project. Specifically, the improvements consist of an increase in system performance- responsiveness and throughput - by judiciously adjusting the parameters of the TSS/360 Table-Driven Scheduler in accordance with the Principles of Balanced-Core Time and Working Set Size. A number of test runs were made, and the results are given, employing different schedule tables. A set of benchmark programs (or script) were developed and used with these tests that were characteristic of a 'typical' or 'realistic' load at this installation. (Author)
