• Copy BatchSubmission to your analysis directory
  

cp -r ../../clange/ExoVV/Analysis/BatchSubmission/

• Create directories AnalysisOutput and AnalysisTemp parallel to BatchSubmissions
  

mkdir AnalysisOutput AnalysisTemp

• Make sure you have an updated version of Python (Python 2.6 or later). You can use the Python version of CMSSW doing
  

cd …CMSSW_5_3_13/src/
cmsenv

• Create your list of infiles in an .xml file and store it under BatchSubmission/xmls/. Use only name of infile and lumi (see test.xml):
  

<In FileName=“dcap:t3se01.psi.ch:22125pnfs/psi.ch/cms/trivcat/store/user/jngadiub/Thea/FLATtuple/HH4b_1000_newCones8/flatTuple_Graviton_1000_newCones8_1.root” Lumi=“1.0”/>
<In FileName=“dcap:t3se01.psi.ch:22125pnfs/psi.ch/cms/trivcat/store/user/jngadiub/Thea/FLATtuple/HH4b_1000_newCones8/flatTuple_Graviton_1000_newCones8_2.root” Lumi=“1.0”/>
<In FileName=“dcap:t3se01.psi.ch:22125pnfs/psi.ch/cms/trivcat/store/user/jngadiub/Thea/FLATtuple/HH4b_1000_newCones8/flatTuple_Graviton_1000_newCones8_3.root” Lumi=“1.0”/>
……

• Create new or edit BatchSubmission/MyTestAnalysisOptions.py. This will be the same for all jobs (signal and background) and should only contain global variables and libraries used (see comments under).
  

loadLibs=[
“libMyTestPackage”, libraries you are using, order matters (separate by comma)
]


loadPacks=[“SFrameCore.par”,
“MyTestPackage.par”, name of your SFrame package+.par
]

compilePacks=[
“../AnalysisPackage”, name of your SFrame package
]

AddUserItems = [
[“InputTreeName” ,“tree”],your global user items
]

#End

• Create python script with job specific configurations (one for signal, one for background), see BatchSubmission/test.py. Here you add all job specific item names, name of in and output file etc (see comments under)
  

#! /usr/bin/python
# -*- coding: utf-8 -*-

path2xml=“$HOME/ExoVV/Analysis/BatchSubmission/xmls” path to xmls
path2tmp=“$HOME/ExoVV/Analysis/AnalysisTemp” path to temporary directory (create this if you have not done so already)
outDir=“$HOME/ExoVV/Analysis/AnalysisOutput” path to output directory
jobName=“clTestJob” name of job (optional name)
cycleName=“MyTestAnalysis” important! must match SFrame cycle name (see sframe config file)
nEventsMax=-1 nr events
nProcesses=2
nFiles=2 nr of files per job
hCPU=“00:30:00”
hVMEM=“3000M”
postFix = ““

dataSets=[
[“Test”, [“test”]], Output name and name of xml containing in file names
]

userItems = [
# [“InputTreeName”, “tree”], job specific item names
]

jobOptionsFile2=open(“MyTestAnalysisOptions.py”, 'r')name of file containing global item names and libraries
command2=”“
for i in [o for o in jobOptionsFile2.readlines()]:
if (”#E” + “nd”) in i : break
command2+=i
jobOptionsFile2.close()
exec command2
userItems += AddUserItems

inputTrees=[“ntuplizer/tree”]name of intput tree
outputTrees=[“analysis”]name of output tree\\

• Compile and run from BatchSubmission with
  

python submitSFrame.py -j test.py –batch

• Output files stored under AnalysisOutput
