The EuroHPC Joint Undertaking (EuroHPC JU) has signed a procurement contract with Bull to deliver LUMI-AI, a next-generation supercomputer to be located in CSC’s data center in Kajaani, Finland. The system is expected to deliver a tenfold increase in artificial intelligence (AI) capacity and nearly double the high-performance computing (HPC) capability of the current LUMI supercomputer. The total value of the LUMI-AI contract, including acquisition, delivery, installation, and maintenance, is EUR 387.8 million. LUMI-AI will strengthen Europe’s capabilities in AI, high-performance computing, data-driven research and innovation as well as competence development.
LUMI-AI will serve as the computing backbone of the LUMI AI Factory, supporting both industrial AI innovation and academic research. Designed for a wide range of workloads, the system will enable breakthroughs in AI training and inference, as well as large-scale scientific simulations.
The LUMI-AI supercomputer is owned by the EuroHPC JU and hosted by the LUMI AI Factory consortium, which includes six countries: Finland, Czechia, Denmark, Estonia, Norway, and Poland. The system is scheduled for deployment in the second half of 2027 at CSC’s new data center in Renforsin Ranta business park in Kajaani, Finland.
The total value of the LUMI-AI contract, including acquisition, delivery, installation, and maintenance, is EUR 387.8 million. Funding is shared equally between EuroHPC JU and the LUMI AI Factory consortium.
With LUMI-AI, EuroHPC JU has now signed its sixth AI Factory procurement contract for a next-generation AI-optimised supercomputer. Together, these systems will form a powerful European AI infrastructure ecosystem, enabling SMEs and startups to access world-class supercomputing resources, unlock the full potential of AI, and drive innovation, growth, and technological leadership across Europe
- states Anders Jensen, EuroHPC JU Executive Director.
The LUMI AI Factory consortium builds on the success of the LUMI supercomputer. I want to thank the EuroHPC JU and the consortium for the great collaboration: together we can build this world-class infrastructure for European researchers. LUMI-AI’s modern capabilities combined with the LUMI-IQ quantum computer will help European researchers and industry tackle unforeseen research and innovation challenges in key fields such as health, climate and disruptive technologies
- says Kimmo Koski, Managing Director of CSC – IT Center for Science.
Top-tier technology with environmental responsibility
The liquid-cooled supercomputer will be based on Bull’s latest BullSequana XH3500 architecture, specifically designed for advanced AI workloads. It will be built on next-generation AMD Instinct™ MI430X GPUs alongside state-of-the-art 6th Gen AMD EPYC™ 256-core processors, providing flexibility across diverse computing workloads.
The other technology partners are IBM, providing an ambitious storage solution based on their Storage Scale technology, as well as Nokia, providing data center networking expertise to build a network that complements the BXI interconnect by Bull.
The system will be complemented by additional compute and storage resources, maximising its overall performance and usability. A key differentiator is its multi-tenant architecture, designed to meet the needs of diverse AI communities, combined with extensive API-based access to support modern development environments.
We are proud to continue our work to support European research and innovation, competitiveness and resilience through developing digital research infrastructures and related capabilities. We want to support the European Commission in its endeavour to reinforce the ‘European way’ to technological sovereignty based on sustainability, human-centricity and European values
- Koski continues.
Sustainability is a central aspect of the project. LUMI-AI is designed to capture and reuse excess heat, which will be fed into Kajaani’s district heating network. The data center construction work also follows ambitious sustainability goals. LUMI-AI will be 100% powered by renewable energy, making it one of the most energy- and eco-efficient supercomputers in the world.
A time for quantum computing integration
The LUMI-AI computing environment will be complemented by a quantum computing (QC) platform, LUMI-IQ,to be delivered by IQM Quantum Computers. Together, LUMI-AI and LUMI-IQ will form a leading hybrid computing platform enabling workloads combining HPC, AI and quantum computing. LUMI-IQ will be located in the same data center as LUMI-AI and be tightly integrated to it.
This integrated approach is expected to enable new forms of scientific workloads that combine traditional simulation, machine learning, and quantum algorithms, opening new research avenues across science and industry. The new LUMI-AI system, together with the LUMI-IQ quantum computing platform will enable European research to drive academic breakthroughs and industrial RDI across Europe and thereby strengthening expertise, employment, and competitiveness across Europe in the 2030’s
