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).
