Issue/Introduction

How do you determine the CPU cores of a system with LSCPU with regards to the Sizing Wizard recommendations?

Environment

Release : 3.7

Component : IM Reporting / Admin / Configuration

Resolution

Based on the below output you would take the number of Sockets (2) and multiply it by the number of Cores per socket (8).  You would not take the Threads per core into account (2) as that equates to hyperthreading and not an actual core.  In this situation you could say this system has 16 cores when comparing it to the Performance Management sizing wizard.
