Title: Cosmological Simulations in Exascale Era,
Abstract: The architecture of Exascale computing facilities, which involves millions of
heterogeneous processing units, will deeply impact on scientific applications.
Future astrophysical HPC applications must be designed to make such computing
systems exploitable. The ExaNeSt H2020 EU-funded project aims to design and
develop an exascale ready prototype based on low-energy-consumption ARM64 cores
and FPGA accelerators. We participate to the design of the platform and to the
validation of the prototype with cosmological N-body and hydrodynamical codes
suited to perform large-scale, high-resolution numerical simulations of cosmic
structures formation and evolution. We discuss our activities on astrophysical
applications to take advantage of the underlying architecture.
