Harvesting energy consumption on European HPC systems: Sharing Experience from the CEEC project
Kajol Kulkarni, Samuel Kemmler, Anna Schwarz +5
Energy efficiency has emerged as a central challenge for modern high-performance computing (HPC) systems, where escalating computational demands and architectural complexity have l…
Large-Scale Simulations of Fully Resolved Complex Moving Geometries with Partially Saturated Cells
P. Suffa, S. Kemmler, H. Koestler +1
We employ the Partially Saturated Cells Method (PSM) to model the interaction between the fluid flow and solid moving objects as an extension to the conventional lattice Boltzmann…
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…
Particle-resolved simulation of antidunes in free-surface flows
Christoph Schwarzmeier, Christoph Rettinger, Samuel Kemmler +5
The interaction of supercritical turbulent flows with granular sediment beds is challenging to study both experimentally and numerically; this challenging task has hampered the adv…
