An exponential integrator/WENO discretization for sonic-boom simulation on modern computer hardware
Lukas Einkemmer, Alexander Ostermann, Mirko Residori
Recently a splitting approach has been presented for the simulation of sonic-boom propagation. Splitting methods allow one to divide complicated partial differential equations into…
Performance optimization and modeling of fine-grained irregular communication in UPC
Jérémie Lagravière, Johannes Langguth, Martina Prugger +3
The UPC programming language offers parallelism via logically partitioned shared memory, which typically spans physically disjoint memory sub-systems. One convenient feature of UPC…
Exponential methods for solving hyperbolic problems with application to kinetic equations
Nicolas Crouseilles, Lukas Einkemmer, Josselin Massot
The efficient numerical solution of many kinetic models in plasma physics is impeded by the stiffness of these systems. Exponential integrators are attractive in this context as th…
Semi-Lagrangian Vlasov simulation on GPUs
Lukas Einkemmer
In this paper, our goal is to efficiently solve the Vlasov equation on GPUs. A semi-Lagrangian discontinuous Galerkin scheme is used for the discretization. Such kinetic computatio…
A low-rank projector-splitting integrator for the Vlasov--Maxwell equations with divergence correction
Lukas Einkemmer, Alexander Ostermann, Chiara Piazzola
The Vlasov--Maxwell equations are used for the kinetic description of magnetized plasmas. As they are posed in an up to 3+3 dimensional phase space, solving this problem is extreme…
Reproducibility, accuracy and performance of the Feltor code and library on parallel computer architectures
Matthias Wiesenberger, Lukas Einkemmer, Markus Held +3
Feltor is a modular and free scientific software package. It allows developing platform independent code that runs on a variety of parallel computer architectures ranging from lapt…
