Geant 4

Overview

Geant4 is a toolkit for the simulation of the passage of particles through matter. Its areas of application include high energy, nuclear and accelerator physics, as well as studies in medical and space science.
The following version is installed on the CSF:

• Geant4 10.5

Restrictions on use

This is not open source software. It does have a license which you should read. GEANT4 is available to all CSF3 users. Please note, there is no access to the source code on CSF3.

Set up procedure

To access the toolkit please load one of the appropriate modulefile:

module load apps/intel-17.0/geant4/10.5

NOTE we now recommend loading module files in your job script rather than on the login node.

Using the Toolkit

Compile your GEANT4 Application

Create your build directory:

mkdir ~/scratch/my_application_build
cd ~/scratch/my_application_build

Compile your code with

cmake -DGeant4_DIR=$GEANT4DIR ~/path/to/my_application_source
make

The executable will be created.
Please do not run your Geant4 application on the login node. Jobs should be submitted to the compute nodes via batch or qrsh for an interactive session.

Run

Serial batch job submission

If your application is interactive, for example, if it produces graphical output, please use qrsh to login to a compute node for an interactive session:

qrsh -l short -cwd bash
module load apps/intel-17.0/geant4/10.5
~/path/to/my_application

If your application isn’t interactive, please submit jobs via batch:

#! /bin/bash --login
#$ -cwd
module load apps/intel-17.0/geant4/10/5
~/path/to/my_application

Parallel batch job submission

Geant4 is not suitable for parallel jobs.
