An Efficient ADER-DG Local Time Stepping Scheme for 3D HPC Simulation of Seismic Waves in Poroelastic Media
Sebastian Wolf, Martin Galis, Carsten Uphoff +4
Many applications from geosciences require simulations of seismic waves in porous media. Biot's theory of poroelasticity describes the coupling between solid and fluid phases and i…
TeaMPI -- Replication-based Resilience without the (Performance) Pain
Philipp Samfass, Tobias Weinzierl, Benjamin Hazelwood +1
In an era where we can not afford to checkpoint frequently, replication is a generic way forward to construct numerical simulations that can continue to run even if hardware parts…
Lightweight Task Offloading Exploiting MPI Wait Times for Parallel Adaptive Mesh Refinement
Philipp Samfass, Tobias Weinzierl, Dominic E. Charrier +1
Balancing the workload of sophisticated simulations is inherently difficult, since we have to balance both computational workload and memory footprint over meshes that can change a…
Fast GPGPU Data Rearrangement Kernels using CUDA
Michael Bader, Hans-Joachim Bungartz, Dheevatsa Mudigere +2
Many high performance-computing algorithms are bandwidth limited, hence the need for optimal data rearrangement kernels as well as their easy integration into the rest of the appli…
