Post-Moore Technologies for Plasma Simulation: A Community Roadmap
Luca Pennati, Erik M. Åsgrim, Jeremy J. Williams +21
Plasma simulations are among the most computationally demanding scientific workloads, combining high-dimensional kinetic evolution, particle-mesh coupling, field solves, and data-i…
Geoelectric Field Caused by Flux Transfer Events in an Ionosphere-Coupled Vlasiator Simulation
Konstantinos Horaites, Markku Alho, Yann Pfau-Kempf +10
We report on the relationship between flux transfer events (FTEs) at Earth's magnetopause and the geoelectric field that is induced near the FTEs' magnetic footpoints. We study thi…
Coalescing MPI communication in 6D Vlasov simulations: solving ghost domains in Vlasiator
Markus Battarbee, Urs Ganse, Yann Pfau-Kempf +3
High-performance computing is used for diverse simulations, some of which parallelize over the Message Passing Interface (MPI) with ease, whilst others may have challenges related…
Porting the grid-based 3D+3V hybrid-Vlasov kinetic plasma simulation Vlasiator to heterogeneous GPU architectures
Markus Battarbee, Konstantinos Papadakis, Urs Ganse +5
Vlasiator is a space plasma simulation code which models near-Earth ion-kinetic dynamics in three spatial and three velocity dimensions. It is highly parallelized, modeling the Vla…
Hybrid-Vlasov simulation of soft X-ray emissions at the Earth's dayside magnetospheric boundaries
Maxime Grandin, Hyunju K. Connor, Sanni Hoilijoki +5
Solar wind charge exchange produces emissions in the soft X-ray energy range which can enable the study of near-Earth space regions such as the magnetopause, the magnetosheath and…
First 3D hybrid-Vlasov global simulation of auroral proton precipitation and comparison with satellite observations
Maxime Grandin, Thijs Luttikhuis, Markus Battarbee +15
The precipitation of charged particles from the magnetosphere into the ionosphere is one of the crucial coupling mechanisms between these two regions of geospace and is associated…
