What LUMI Supercomputer does

LUMI is a EuroHPC pre-exascale supercomputer infrastructure project operated under the EuroHPC Joint Undertaking and hosted at the CSC – IT Center for Science data center in Kajaani, Finland. The system is co-funded by the European Union (via the Connecting Europe Facility and Horizon 2020) and 11 participating states: Finland (host), Belgium, Switzerland, the Czech Republic, Denmark, Estonia, Iceland, the Netherlands, Norway, Poland, and Sweden. The platform comprises the core LUMI system and the LUMI-G GPU-accelerated partition, supplemented by a Lustre parallel file system and a dedicated LUMI AI Factory for AI/ML workloads. User support is delivered through the LUMI Documentation Portal, a service-status portal, training events, and a YouTube/LinkedIn/Bluesky presence.

LUMI serves European research communities spanning meteorological and climate science (e.g., the Danish Meteorological Institute via the SAPIEN project), fundamental physics and astrophysics (e.g., Polish gamma-ray burst simulations), and AI/ML research including AI agent infrastructure. Access is not sold commercially; compute resources are allocated to qualifying research projects through periodic open-access grant competitions administered by national supercomputing centers (Sigma2 for Norway, IT4Innovations for the Czech Republic) under EuroHPC JU coordination. Effectively, LUMI's revenue mechanics are pooled sovereign and EU appropriations rather than customer payments.

LUMI competes in the pre-exascale tier with other EuroHPC systems and is consistently ranked in the global Top500 at ISC High Performance events. Competitive differentiators include the depth of multi-country capital backing, regulatory protection via EuroHPC JU governance, the energy-efficient cold-climate siting in Kainuu, and a focused LUMI AI Factory that positions the system as a credible European alternative for large-scale AI training and inference workloads.
