High-performance computing Lab (HPCLab)
Our research group develops and utilises high-performance and data intensive computing (HPC) methods and applications for heterogeneous NUMA-architectures.
Our spearhead area is astroinformatics, namely methods and tools for simulating and analysing data from complex (astro)physical systems, such as turbulent fluids, the Sun, and interstellar matter in galaxies. The developed methods include simulation tools accelerated with graphics processing units, and data-analysis tools employing machine learning. Our current projects aim at understanding, predicting, and mitigating the harmful effects from solar magnetic activity (ERC consolidator grant UniSDyn, ERC proof-of-concept grant SYCOS, Inno4Scale project NEOSC).

Evidence of turbulent dynamo action in the Sun
Astroinformatics research group has determined magnetic helicity spectrum from the solar surface observations using the recently developed two-scale formalism.
Surface gravity oscillation mode shows remarkable solar cycle dependence
12 years of satellite data was used to reveal an enigmatic behaviour of the surface-gravity wave energy contained in the most quiet regions on solar surface.
LUMI-G pilot
VISSI-project was selected as LUMI-G pilot
Dust destruction in Supernova blast waves
A supernova explosion blasts hot supersonic plasma, destroying more interstellar dust in its path than fits current theory or observations of dust abundances in early galaxies.People
