Hybrid Workshop: Space Plasma Simulations with Vlasiator on LUMI

The Plasma-PEPSC Centre of Excellence, in collaboration with the EuroCC National Competence Centre Sweden (ENCCS), hosted a hybrid training workshop from 13-15 February in Stockholm. This workshop was designed to bring together code developers, researchers, and research software engineers engaged in space plasma simulation technologies. The workshop participants had the unique opportunity to learn how to use and program the Vlasiator package (a state-of-the-art tool for plasma simulation and analysis especially designed for space simulations) on the EuroHPC LUMI supercomputer. Expert Vlasiator developers from the University of Helsinki and the Finnish Meteorological Institute provided comprehensive training throughout the workshop on utilising the Vlasiator code’s capabilities, including data analysis tools to understand space simulations. The sessions were structured to cater to both beginner users and experienced space researchers. In addition to hands-on training on using Vlasiator on the LUMI supercomputer, the workshop featured a series of presentations and discussions highlighting the latest advancements in plasma simulation techniques for space simulations. Attendees from the space physics and space weather community at the KTH Royal Institute of Technology and Uppsala University could network with peers, share their experiences of space simulations, and explore potential collaborations across different plasma physics and simulation projects. The hybrid format of the event also allowed remote participants from France and Germany to engage in the training activities, broadening the workshop’s reach and impact. The lectures about using Vlasiator on the LUMI system are collected on the Plasma-PEPSC YouTube channel ( www.youtube.com/@PlasmaPEPSC ).
