The latest version of geant4 (9.5) is installed on CentOS clusters under /opt/sharcnet/geant4/9.5/gcc .
Geant4 comes with many examples useful for testing purposes. You can start with a simple test. For instance, here are the steps to compile and run an analysis example A01 in ~/testing directory inside your home directory:
module unload intel module load gcc/4.5.3 module load geant4/gcc/9.5 export G4WORKDIR=~/testing cp -a /opt/sharcnet/geant4/9.5/gcc/examples/extended/analysis/A01 $G4WORKDIR/A01 source /opt/sharcnet/geant4/9.5/gcc/share/Geant4-9.5.0/geant4make/geant4make.sh export CXX=g++ cd $G4WORKDIR/A01 make # LD_RUN_PATH is ignored by this makefile, so need to set LD_LIBRARY_PATH export LD_LIBRARY_PATH=/opt/sharcnet/gcc/4.5.3/lib64:$LD_LIBRARY_PATH sqsub -q serial -r 5m -o output.log ../bin/Linux-g++/A01app
Note that geant4 makefiles will omit the environment variable $LD_RUN_PATH which has a path to gcc libraries, instead encoding only its own path to the application library you are building ($G4WORKDIR/tmp/Linux-g++/A01app in our example), so we need to set LD_LIBRARY_PATH by hand before running geant4 as illustrated by the example above.
