Abstract
The Geant4 simulation toolkit needs to be optimized for central processing unit (CPU) time and memory size in order to be used for a high luminosity Large Hadron Collider (LHC) experiment. We have developed a low-energy physics profiling system and studied Geant4 with respect to both software and hardware. The results of profiling with Geant4 for low-energy physics were provided to the users and developers of the Geant4 simulation toolkit. In the case of the software, we performed profiling for dependence on different Geant4 versions and provided feedback to Geant4 developers. Profiling for dependence on the number of events showed their linear dependency. In the case of the hardware, we performed profiling for machine dependency on the KISTI-4 supercomputer. This action showed that machines were homogenous. The results obtained in this study will serve as a reference for Geant4 users.
