Geant4 based simulation of radiation dosimetry in CUDA

Challenges in Monte Carlo Event Generator Software for High-Luminosity LHC

“…In this respect, generators should be somewhat easier to reengineer efficiently for GPUs than detector simulation software (notably Geant4 [156]), where the abundance of conditional branching of a stochastic nature may lead to "thread divergence" and poor software performance (see, for examples, Refs. [157][158][159][160][161][162]).…”
