Abstract: Statistical algorithms of modeling of radiation cascade transport in compound objects by use of heterogeneous computers are developed. Generation of electron fluxes by X-radiation, bremsstrahlung and radiative electron emission are considered. Economy scheme of counting the particle generations is implemented. An approach of hybrid paralleling of the calculations for effective application of CPU and GPU is worked out. The approach is based on modification of particle trajectories tree handling method. The applications of the developed simulation tool are presented in terms of results obtained with use of hybrid computer K-100 and compared to MCNP.
Keywords: radiation transport, cascade process, heterogeneous supercomputer, hybrid paralleling.
