Abstract: Core-collapse supernovae (CCSNe) are integral to the formation and distribution of heavy elements across the universe. However, CCSNe are highly complex and inherently non-linear phenomena. Large-scale simulations of these cosmic events can provide us a glimpse of their hydrodynamic and nucleosynthetic processes which are difficult to observe. To enable these massive numerical simulations on high-performance computing (HPC) centers, this study uses FleCSPH, a parallel and distributed code, based on the smooth-particle hydrodynamics (SPH) formulation. In the recent years, the HPC architecture has evolved and the next generation of exascale computers are expected to feature heterogenous architecture. Therefore, it is important to maintain code portability across platforms. This work demonstrates code portability of FleCSPH through the incorporation of Kokkos C++ library and containers using Charliecloud.
