This interactive approach can be useful. However, this method is not recommended if your internet connection is poor or you have to run
topasfor a long time.On a HPC, running OpenTOPAS in batch mode is preferred. Please visit OpenTOPAS (Batch, Intel) on LANTA to install OpenTOPAS that suitable for batch mode instead.
This guide is largely derived from https://opentopas.readthedocs.io/en/latest/getting-started/Debian.html#. It is recommended to visit the page for more detailed explanation of each [Step X] .
1. Load required modules and set environment variables [Step 1-4]
Paste the below lines into your terminal. (Do NOT put these directly in ~/.bashrc.)
module purge
module load expat/2.5.0
module load X11/20231019-cpeCray-23.03
module load libGLU/9.0.3-cpeCray-23.03
module load HarfBuzz/8.2.2-cpeCray-23.03
module load CMake/3.26.4
export CC=cc CXX=CC FC=ftn F77=ftn F90=ftn2. Download Geant4 [Step 5]
mkdir $HOME/Applications
mkdir $HOME/Applications/GEANT4
cd $HOME/Applications/GEANT4
wget https://gitlab.cern.ch/geant4/geant4/-/archive/v11.1.3/geant4-v11.1.3.tar.gz
tar -zxf geant4-v11.1.3.tar.gz3. Install Geant4 [Step 7]
cd $HOME/Applications/GEANT4/
rm -rf geant4-install geant4-build
mkdir geant4-{build,install}
cd geant4-build
cmake ../geant4-v11.1.3 -DGEANT4_INSTALL_DATA=OFF -DGEANT4_BUILD_MULTITHREADED=ON -DCMAKE_INSTALL_PREFIX=../geant4-install -DGEANT4_USE_QT=OFF -DGEANT4_USE_OPENGL_X11=ON -DGEANT4_USE_RAYTRACER_X11=ON
make -j8 install
cd $HOME/Applications/GEANT4/geant4-install
ln -s lib64 lib-DCMAKE_PREFIX_PATH=/usr/lib/qt5 -DGEANT4_USE_QT=ONis changed to-DGEANT4_USE_QT=OFF./geant4-install/libis symbolically linked to/geant4-install/lib64.
4. Download G4DATA [Step 6]
5. Download OpenTOPAS [Step 8.1]
6. Install GDCM [Step 8.2-8.3]
7. Install OpenTOPAS [Step 8.4]
8. Create a wrapper script of topas [Step 9.1.b]
9. Run OpenTOPAS on LANTA
You can request an interactive session by executing, for example,
The X11 forwarding feature may require further setup.
If you use MobaXterm, the X11 forwarding should be supported by default.
If you login from a Linux terminal, set
ForwardX11Trustedin/etc/ssh/ssh_configtoyesand then login usingssh -Y username@lanta.nstda.or.th.If you login from a Windows/Mac terminal, you need to install and run a X11 server, such as Xming and XQuartz, while using. Then login using
ssh -Y username@lanta.nstda.or.th.
Please visit Interactive session for more details.
After the requested resources are allocated, you can use this session to run topas and interactively execute commands afterwards. A graphic window should appears when objects are rendered. For example, run
