Direct N-body code designed for a cluster based on heterogeneous computational nodes

David Goz, Luca Tornatore, Sara Bertocco & Giuliano Taffoni
The ExaNeSt H2020 project is developing an exascale ready prototype based on hybrid hardware (CPUs+accelerators). Astrophysical codes are used to test and validate the exascale platform. At the same time, astrophysical applications must be re-engineered in order to exploit heterogeneous hardware. We present and test the parallel scheme of a state-of-the-art direct N -body code (called ExaHiGPUs) conceived to be run on hybrid architecture.
