Offline software for Phase I (2018) heavy-ion reco

Frontier development recipe (i.e., instantly out of date)

CMSSW setup

cmsrel  CMSSW_10_3_0_pre4
cd  CMSSW_10_3_0_pre4/src

Reco cfgs

Latest customizations and mult-threading options may be found here: /afs/

cmsDriver commands

See the RelVal workflows for HI reco and pp reco: -l 150 -n -e -l 158 -n -e  

The workflow can be quickly validated with a similar command: -l 158 --useInput all -t 4 

These workflows run peripheral Hydjet events, but of course you can change the generator to whatever you want, e.g., Hydjet_Quenched_MinBias_5020GeV_cfi
