VLQ QQbar generation with MadGraph5_aMC@NLO using gridpacks

ATLAS Intro from CAMPFIRE 2019

Lesson 1: Git and Unix

Lesson 2: Numpy and Pandas

Lesson 3: ROOT/PyRoot/uproot

Lesson A: ROOT and Python introduction from Nevis Labs:

The classic, first python tutorial: https://docs.python.org/3/tutorial/

Fun with D-Wave:

create a free account.
go to resources-> learning and docs -> interactive examples

also fun quantum game: http://helloquantum.mybluemix.net


This page describes the generation of VLQ pair production samples using Madgraph with gridpacks.
The primary reference for these instructions is the excellent twiki MadGraph5aMCatNLOForAtlas: https://twiki.cern.ch/twiki/bin/view/AtlasProtected/MadGraph5aMCatNLOForAtlas

The instructions below work on a Tier3, presumable lxplus also. If you use lxplus you may run into time limits.


Log in, (and highly recommended to use tmux), setupATLAS (see SoftwareTutorial for help).
Go to your work area $WORK (output is ~Gb so not in your home area).

mkdir VLQ_PP
mkdir PL_VLQ_UFO

You need to copy and untar the model files: PL_VLQ_UFO.tar.gz, at least until we include this model in the release. Then:

mkdir run
cd run

Copy the attached jobOptions MC15.999999.MGPy8EG_TTbar_gridpack.py the run directory (again, will add to svn eventually).
Note that this JO does not run Pythia (not necessary for grid packs) and does not care about the number of events you ask it to generate.


You may want to use all the CPU processors available.
Find out how many processors are on the machine with:

cat /proc/cpuinfo |grep processor

If you use all the processors, be nice to other users.
To enable multi-core multi-core in Athena:


Note in the instructions that if you want to run Pythia after this you have to add a few lines to your JO.

And not run the job with:

Generate_tf.py --ecmEnergy=13000. --maxEvents=-1 --runNumber=999999 --firstEvent=1 --randomSeed=123456 --outputEVNTFile=EVNT.root --jobConfig=MC15.999999.MGPy8EG_TTbar_gridpack.py

With dual 4 core Intel i7-4790 CPU @ 3.60GHz machine it takes about 13 hours. Expect high variation.


The job will not end cleanly. This is expected.
