Geant4 Release Regression Testing on the Grid

Geant4 Production: Instructions

Introduction

This webpage describes all steps required to setup and run the Geant4 production.

Two areas are of importance for the production procedure:

• RUN AREA /afs/cern.ch/sw/arda/install/DIANE/Geant4/G4Prod The required subdirectories are:
  • run: contains all necessary scripts for executing the production
  • cand: directory from which the Geant4 candidate is downloaded to the sites
• OUTPUT AREA /afs/cern.ch/sw/geant4/stat_testing/june08 The required subdirectories are:
  • results: used for storing all the outputs
  • code: used for storing the Geant4 candidate versions

Preparing production run

Setting up environment (required for each run)

Commands assume bash shell.

Creating output directory

Create a new output directory in the output area. As a further step create within this new output directory a directory called "applications" E.g.

OUTPUT_DIR=/afs/cern.ch/sw/geant4/stat_testing/june08/results/output_$USER
cd $OUTPUT_DIR
mkdir -p diane
mkdir -p gangadir

Placing DIANE application adapter

Get the DIANE application adapter from CVS:

cd $OUTPUT_DIR/diane
cvs -d :kserver:isscvs.cern.ch:/local/reps/diane co apps/G4Production 

Setting up grid/tool environment

Set the grid/tool environment by executing the following command in bash:

bash
source /afs/cern.ch/sw/arda/install/DIANE/Geant4/G4Prod/run/prodsetup_slc4.sh

The ganga configuration is in: /afs/cern.ch/sw/arda/install/DIANE/Geant4/G4Prod/run/ganga-geant4-june08-config.ini

Normally you do not need to change it, so make sure that your ~/.gangarc configuration file does contain unnecessary modifications (use ganga -g to create an "empty" configuration file).

Creating the task scripts describing the physics configurations

Creating directory for task scripts

Create a subdirectory, which will contain the task scripts, in the directory /afs/cern.ch/sw/arda/install/DIANE/Geant4/G4Prod/run/taskscripts. E.g. cd /afs/cern.ch/sw/arda/install/DIANE/Geant4/G4Prod/run/taskscripts mkdir cand1_QGSP

Creating task scripts

Change to the directory created in II.2.A and use the script create_pyscripts.pl in combination with the template executable.template to create the required task scripts. IMPORTANT: Change the reference and candidate names in the template to the current tags before creating the task scripts. E.g. perl create_pyscripts.pl -pydir cand1_QGSP -template executable.template

Adapting the job description file and placing the candidate version

Copying candidate to download directory

Copy the current Geant4 candidate tarball to the directory /afs/cern.ch/sw/arda/install/DIANE/Geant4/G4Prod/cand

Preparing DIANE job description file

Introduce following two changes into the DIANE job description file /afs/cern.ch/sw/arda/install/DIANE/Geant4/G4Prod/run/runfiles/G4Prod_$USER.run

1. Change the path of local_exe_dir to be in coincidence with the full path of the subdirectory of taskscripts, which was created in II.2.A and which contains the task scripts E.g. local_exe_dir = '/afs/cern.ch/sw/arda/install/DIANE/Geant4/G4Prod/run/taskscripts/cand1_QGSP'

2. Change local_cand_name to the name of the current candidate tar-ball E.g. local_cand_name = 'g4prod-1.tgz'

Invoking production run (on lxb7232.cern.ch)

Run the following command in the directory /afs/cern.ch/sw/arda/install/DIANE/Geant4/G4Prod/run

env ORBendPoint=giop:tcp::23001 diane-run /afs/cern.ch/sw/arda/install/DIANE/Geant4/G4Prod/run/runfiles/G4Prod_$USER.run

In another window:

cd /afs/cern.ch/sw/arda/install/DIANE/Geant4/G4Prod/workers
diane-env -d `which ganga` LCG.py --diane-worker-number=10

Hint: CERN CE selection --CE ce117.cern.ch:2119/jobmanager-lcglsf-grid_geant4 (from 101 to 117)

Useful commands

Most command accept --help

Killing master: diane-master-ping kill

Check if master alive: diane-master-ping

Run worker interactively for debugging:

export VO_GEANT4_SW_DIR=/afs/cern.ch/sw/geant4/stat_testing/june08/code/dir32bits
diane-worker-start --workdir=/tmp/blah
