Abstract: Summary We give an overview of the problems and the current status of our two-dimensional (core collapse) supernova modelling, and discuss the system of equations and the algorithm for its solution that are employed in our code. In particular we report on our recent progress, and focus on the ongoing calculations that are performed on the NEC SX-8 at the HLRS Stuttgart. We discuss the case of low-mass progenitors below about ten solar masses, where we have obtained robust explosions, as well as the case of more massive progenitors, exemplified by a 15 M⊙ mass star, for which we have also observed a developing explosion in one simulation. Several open issues are mentioned, and the need for a larger set of models, evolved to sufficiently late times, is emphasized. We stress that a highly parallel code, capable of exploiting the multi-node architecture of the NEC SX-8, is indispensable for addressing these unresolved questions.
