The Relatively New LSPR and the Latest z Systems Processors

Project and Program: MVS, MVS Performance

Tags: Proceedings , 2017 , SHARE San Jose 2017

At the time of the z196 introduction, the LSPR was significantly enhanced to be based on a measure of a workload's intensity of use of a processor's memory hierarchy. Since then the methodology has seen much validation and continues to be used up through the latest z Systems processors. This session will discuss the theory behind the relatively new metric (Relative Nest Intensity) and its basis on data gathered using CPU MF. Its application to capacity sizing will be illustrated by contrasting the performance of the latest z Systems processors.-Gary King-IBM Corporation
