Abstract

Computer performance evaluation studies give the analyst some insight into the factors that may significantly affect system performance. In this paper, we look into the CPU and memory utilization of the Sperry 1100/61 computer.Data on system performance and load characteristics are collected by the Software Instrumentation Package (SIP). SIP, embedded in the operating system, is an event-oriented monitor. Together with the Performance Analysis Routines (PAR), a programmable data-reduction package, the user has a high degree of control over the manipulation of SIP data and the creation of reports. We used PAR to analyse the SIP data to graph CPU and memory utilization. The aim is to see if memory upgrades and tuning of SYSGEN parameters aftecting CPU allocation is needed. A simulator program based on the major system queues and queueing algorithms was written to see how the system would perform under different workloads.
