Re-engineering parallel astrophysical simulation codes for heterogeneous exascale computing architectures

Professor Andrea Mignone, of the High-Energy Astrophysical group at the University of Torino, explains how the EU-funded SPACE Centre of Excellence is harnessing exascale computing to power the next generation of astrophysical research and scientific discovery. Modern astronomy is undergoing a profound transformation. New generations of observatories are producing unprecedented volumes of data, enabling scientists to investigate the Universe with extraordinary precision. Turning these observations into scientific discoveries requires numerical simulations capable of reproducing complex physical processes across enormous spatial and temporal scales. High-performance computing has therefore become the third pillar of modern astrophysics, alongside theory and observation.
