Abstract

SPH-EXA is a C++20 simulation code for hydrodynamics simulations (with gravity and other physics), parallelized with MPI, OpenMP, CUDA, and HIP. SPH-EXA is built with high performance, scalability, portability, and resilience in mind. Its SPH implementation is based on SPHYNX, ChaNGa, and SPH-flow, three SPH codes selected in the PASC SPH-EXA project to act as parent and reference codes to SPH-EXA. The performance of standard codes is negatively impacted by factors such as imbalanced multi-scale physics, individual time-stepping, halos exchange, and long-range forces. Therefore, the goal is to extrapolate common basic SPH features, and consolidate them in a fully optimized, Exascale-ready, MPI+X, SPH code: SPH-EXA.
