A simple application
The environment variable G4LEDATA for low energy EM data is required.
Use CMake on Geant4 library installed with CMake build.
This example requires G4mpi library to be installed (see examples/extended/parallel/MPI/source/REDME.md)
Follow these commands,
> mkdir build > cd build > cmake -DG4mpi_DIR=<where-G4mpi-wasintalled>/lib[64]/G4mpi -DCMAKE_CXX_COMPILER=mpicxx \ -DGeant4_DIR=<your Geant4 install path>/lib[64]/Geant4-V.m.n <path-to-source> (V.m.n is the version of Geant4, eg. Geant4-9.6.0) > make > make install
Replace mpicxx with your MPI-compiler wrapper.
> mpiexec -n # ./exMPI01 [run.mac]
