The latest version of geant4 (9.5) is installed on CentOS clusters (see the table at the top of this page) under _/opt/sharcnet/geant4/9.5/gcc_. We also have the older version 4.9.1 installed on some systems, but it is no longer updated, so for the newest geant4 please log in to the CentOS clusters.
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/11.0.083 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.
