Rivet + Different MC Generators for Jet Studies

1. Setup naf: source setup_naf.sh

#!/bin/sh
module use -a /afs/desy.de/group/cms/modulefiles/
module load cmssw
ls -la /cvmfs/cms.cern.ch/
source /cvmfs/cms.cern.ch/cmsset_default.sh

2 Install Darwin

git clone https://gitlab.cern.ch/DasAnalysisSystem/Darwin.git
cd Darwin
source setup
make clean
make

(don't use make -j .... )

3. Compile Darwin

cd Darwin/CMSSW_12_4_0/src
cmenv
scram b -j `nproc`

4. make Ntupliser/src directory and put RivetNtupliser.cc and BuildFile.xml there and python config file.

5. Install Core: source setup_DAS.sh and build the Rivet

#!/bin/bash
cmsrel CMSSW_10_6_30
cd CMSSW_10_6_30/src
cmsenv
git clone https://gitlab.cern.ch/gparaske/Core.git
git checkout Rivet
scram b -j `nproc`

4. Clone this repo and put its DAS workflow on Darwin, recompile

git clone https://github.com/AliAlkadhim/NP-MC-JetTuning.git
cp -r DAS_RivetNtupliser/RivetNtupliser/* Core

Running cd Ntupliser && tree displays all the different directories and files in each directory

tree

Starting a blank EDAnalyzer (with mkedanlzr DemoAnalyzer) gives the following template

With the Buildfile in plugins being DAS kind of follows this, but with internally defined plugins, with Core having these subpackages

For example, the JEC subpackage:

TODO: File better directory management.

• export DOCKER as the path to the docker work dir, and REPO as the shared directory inside docker, where my repo is mounted
• Go to DOCKER to install all the stuff, and REPO where you run stuff

1. Run the image interactively

docker run --rm -v /home/ali/Desktop/Pulled_Github_Repositories/NP-MC-JetTuning:/work/shared --privileged -it hepstore/prof2-tutorial 

2. Get HEPMC3

source install_hepmc3.sh

3. Get the pythia example files, compile main42 and test it

mkdir pythia && cd pythia && wget https://pythia.org/download/pythia83/pythia8309.tar 
&& tar -xf pythia8309.tar

3. Compile main42.cc for your system

4. Make rivet analysis and compile (with root flag -r)

rivet-build -r RivetRIVET_NTUPLIZER.so RIVET_NTUPLIZER.cc
rivet --pwd -a RIVET_NTUPLIZER ../pythia/pythia8309/examples/42_test.hepmc
