Introduction

CMSSW Performance Suite Offline Guide

• The CMSSW Performance Suite documentation
• How to run the CMSSW Performance Suite
• CMSSW Performance Suite CMS.RelVal results - The official results for the RelVal execution of the performance suite. As you can see there are several directories, Step1, Step2, GEN-SIM,DIGI, L1-RECO for the different steps run by RelVal at each (pre-)release. There is also a directory Regression, that contains the same subdirectory structure, designated to publish the results of regression analysis between releases already available. Of course individual users can publish their results in other servers/locations using the CMSSW Performance Suite publishing script
