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…
