Abstract

Supernova explosions are among the most powerful cosmic events, whose physical mechanism and consequences are still incompletely understood. We have developed a fully MPI-OpenMP parallelized version of our VERTEX-PROMETHEUS code in order to perform three-dimensional simulations of stellar core-collapse and explosion on Tier-0 systems such as Hermit at HLRS. Tests on up to 64,000 cores have shown excellent scaling behavior. In this report we present the system of equations and the algorithm for its solution that are employed in our code VERTEX-PROMETHEUS. We also discuss the parallelization of VERTEX-PROMETHEUS and present our progress in porting, optimizing, and performing production runs on a large variety of machines, starting from vector machines and reaching to modern systems. In particular the results of our efforts to achieve good parallel scaling on the new Cray XE6 at HLRS Stuttgart are highlighted.
