A code for Monte Carlo simulations of radiation transport using a Graphics Processing Unit (GPU) is introduced. The code has been developed using the CUDATM programming model, an extension to the C language that allows the execution of general purpose computations on the new generation of GPUs from NVIDIA. The accurate Compton and Rayleigh interaction models and interaction mean free paths from the PENELOPE package, and a generic voxelized geometry model, have been implemented in the new code…
