TERRA-NG v1.0: Extreme-Scale, GPU-accelerated Mantle Convection
Fabian Böhm, Nils Kohl, Ponsuganth Ilangovan +7
We present TERRA-NG, a portable, GPU-accelerated, matrix-free mantle-convection code. A single Kokkos C++ implementation runs at scale on NVIDIA, AMD, and Intel GPU supercomputers.…
Fundamental Data Structures for Matrix-Free Finite Elements on Hybrid Tetrahedral Grids
Nils Kohl, Daniel Bauer, Fabian Böhm +1
This paper presents efficient data structures for the implementation of matrix-free finite element methods on block-structured, hybrid tetrahedral grids. It provides a complete cat…
Efficiency and scalability of fully-resolved fluid-particle simulations on heterogeneous CPU-GPU architectures
Samuel Kemmler, Christoph Rettinger, Ulrich Rüde +2
Current supercomputers often have a heterogeneous architecture using both CPUs and GPUs. At the same time, numerical simulation tasks frequently involve multiphysics scenarios whos…
