Abstract: Performing high-resolution, high-fidelity, three-dimensional simulations ofType Ia supernovae SNe Ia requires not only algorithms that accuratelyrepresent the correct physics, but also codes that effectively harness theresources of the most powerful supercomputers. We are developing a suite ofcodes that provide the capability to perform end-to-end simulations of SNe Ia,from the early convective phase leading up to ignition to the explosion phasein which deflagration-detonation waves explode the star to the computation ofthe light curves resulting from the explosion. In this paper we discuss thesecodes with an emphasis on the techniques needed to scale them to petascalearchitectures. We also demonstrate our ability to map data from a low Machnumber formulation to a compressible solver.
