Project ExaHyPE

The supercomputers of tomorrow need new software

Computer-based simulations drive progress in the field of science. In addition to theory and experiments, simulations have long since been crucial for acquiring knowledge and insight. Supercomputers allow for the computation of increasingly complex and precise models. A billion billion, i.e. 1018 computer operations per second (1 exaflop/s) is the level of performance that the next generation of supercomputers should be able to deliver. In order to be able to leverage the incredible processing power of exascale systems for correspondingly comprehensive simulation tasks, the entire supercomputing infrastructure, including the software, must be prepared for such systems. However, programming such supercomputers is a challenge. In October 2015, the European Commission began funding ‘’ExaHyPE’’ („An Exascale Hyperbolic PDE Engine“), an international project coordinated at the Technische Universität München, which seeks to establish the algorithmic foundations for exascale supercomputers in the next four years. The aim is to develop novel software, initially for simulations in geophysics and astrophysics, which will be published as open-source software for further use.
