Load Balancing in Strongly Inhomogeneous Simulations -- a Vlasiator Case Study
Leo Kotipalo, Markus Battarbee, Yann Pfau-Kempf +2
Parallelization is a necessity for large-scale simulations due to the amount of data processed. In this article we investigate different load balancing methods using Vlasiator, a g…
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…
3D propagation of relativistic solar protons through interplanetary space
S. Dalla, G. De Nolfo, A. Bruno +5
Context. Solar Energetic Particles (SEPs) with energy in the GeV range can propagate to Earth from their acceleration region near the Sun and produce Ground Level Enhancements (GLE…
