In this seminar we will present our experience with porting 200K line Fortran codebase onto GPU: SixTrack model - the LHC Accelerator Beam Dynamics. The first part will be dedicated to the steps of source code transformation, modifications into crlibm and cernlib, compilation and execution. In the second part we will discuss performance evaluation results in comparison with SixTrack multi-process ensemble simulation with MPI.
