Parallelization of track for large scale beam dynamics simulation in linear accelerators

Large scale beam dynamics simulations are important to support the design and operations of an accelerator. From the beginning, the beam dynamics code TRACK was developed to make it useful in the three stages of a hadron (proton and heavy-ion) linac project, namely the design, commissioning and operation of the machine. In order to combine the unique features of TRACK with large scale and fast parallel computing we have recently developed a parallel version of the code. We have successfully benchmarked the parallel TRACK on different platforms: BG/L and Jazz at ANL, Iceberg at ARSC, Lemieux at PSC and Seaborg at NERSC. We have performed large scale end-to-end simulations of the FNAL proton driver where 10(8) particles were tracked. The actual parallel version has the potential of simulating 10(9) particles on 10 racks with 20,480 processors of BG/L at ANL, which will be available next year. After a brief description of the parallel TRACK, we will present results from highlight applications.
