Our postdocs were successful in obtaining supercomputer time on the Czech supercomputer infrastructure IT4Innovations. Diego Calderón won 26 000 node hours (approx. 900 000 CPU hours) on Barbora cluster to perform radiation hydrodynamics simulations of transients. Damien Gagnier won 36 000 node hours (approx. 4 600 000 CPU hours) on the brand new Karolina cluster to develop 3D hydrodynamic simulations of common envelope.
