Generating Higgs Events on the grid

A specific example

We'll describe here an example where we'll generate $H_{\mu }\rightarrow ZZ\rightarrow XXYY$ where you can pick your favorite Higgs mass and Z decay channel. This exercise also allows you to test the script on your local ATLAS setup. First make sure this runs before submitting 100's of jobs onto the grid.

The necessary files

For each ATLAS job op the grid we'll need the following files:

A joboptions file for our Athena job

(Here you specify the physics process and details of the output. In our case: Run pythia, atlfast and produce a CBNT output file)

The 'basic' input file is called

A shell script that will be run on the remote grid machine

(The ATLAS settings will be set and the athena job will be started by this script)

A JDL file containing the names of all required input and output file

To facilitate the handling of a large number of jobs we have added two more scripts

A script that produces all input files

A general tool to manage your jobs on the grid (gridmgr)

On your local machine
