LUMI EuroHPC, one of the fastest supercomputers in the world, is located in CSC’s data center in Kajaani. LUMI will be fully operational in May 2022, and will then offer the state-of-the-art supercomputing platform for European research and industry.


Promoting sustainable development in Europe 

LUMI is a unique European supercomputer project involving ten European countries as well as the European Union's EuroHPC Joint Undertaking, which seeks to improve research, employment and competitiveness in Europe.

The implementation of the LUMI project is unique worldwide in both its environmental benefits and cost-effectiveness. It is leading the way in achieving ambitious climate targets in the ICT sector and optimizing the overall costs of an energy-intensive data center industry.

In June 2019, the EuroHPC Joint Undertaking (JU) decided to locate one of three high-speed, pre-exascale supercomputers in CSC's Kajaani data center. The two other EuroHPC flagship supercomputers are located in Spain and Italy. When compared with the environmental load and total costs of the other EuroHPC projects, LUMI is in a class of its own.

The total cost of the LUMI project is approximately EUR 202 million, half of which is covered by the European Union and half by the countries of the LUMI consortium. In addition, LUMI and CSC have received European Regional Development Fund (ERDF) funding granted by the Regional Council of Kainuu. The purpose of the grant is to strengthen Kajaani's data center ecosystem and improve international awareness.
