Recent Advances in Maxwell Solvers for PIC Simulations Across Architectures
Presenter
DescriptionIn this talk we present our experiences in developing architecture-independent linear solversfor a particle-in-cell simulation code. The algebraic multigrid solvers are part of theTrilinos library MueLu. The solvers utilize the Kokkos ecosystem (Kokkos core and KokkosKernels) for portability across architectures. We will briefly describe the simulation codeand the underlying solver algorithms. We'll then describe some of the challenges faced inimproving both strong and weak scaling across architectures, as well as solution approachesto those challenges. Finally, we'll present numerical results across a variety of architectur(CPU, ARM, and GPU) that validate our approach.
