Abstract

The massive increase of computational power over the past decades has established numerical models of planetary interiors to one of the principal tools to investigate the thermo-chemical evolution of terrestrial bodies. Large scale computational models have become state of the art to investigate the interior heat transport, surface tectonics and chemical differentiation of planetary bodies across the Solar System and beyond. In the present work we present large scale numerical simulations performed using the mantle convection code Gaia in spherical and Cartesian geometry. The results have been obtained on the HLRS system Hornet running on 54 × 103 computational cores. The strong scaling results show an optimal speedup for a grid with 55 million computational points corresponding to 275 million unknowns.
