= GUARDYAN || GUARDYAN (GpU Assisted Reactor DYnamic ANalysis) is a Monte Carlo based neutrontransport program running on GPU (Graphics Processing Unit). The simulation tracks neutrons in a three dimension space bounded by second degree surfaces while they interact with the isotopes present in the region. Cross Section Data may be given in ACE (A Compact ENDF ) format coming from ENDF (Evaluated Nuclear Data File) cross section table.
