- LUMI’s immense computing capacity is used in data and computing intensive research across various disciplines. Up to 20% of LUMI’s capacity is reserved for industrial use.
- Around 3500 scientific projects have been running on LUMI, and over half of LUMI’s computing resources have been utilized for AI-related research and innovation.
- The LUMI data center is one of the greenest in the world.
- LUMI’s waste heat is used to heat up hundreds of households annually in the city of Kajaani.
- LUMI runs on 100% renewable power.
- High security and safety standards (ISO 27001).
- LUMI and the projects utilizing the system’s power have received multiple global awards throughout the years from HPCwire Readers’ and Editors’ Choice Awards, DCD Awards, Electrical Review and Data Centre Review Excellence Awards, Data Centre Awards and HPC Innovation Excellence Awards.
LUMI-AI supercomputer
LUMI-AI will gradually replace the current LUMI supercomputer. LUMI-AI will enable breakthroughs in AI training and inference, as well as large-scale scientific simulations. The system will be delivered by Bull and it will be located in CSC’s new data center in Kajaani, Finland. It 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 system is scheduled for deployment in the second half of 2027.
LUMI-AI system architecture
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 6thGen 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.

LUMI-IQ – experimental quantum computing platform
The LUMI-AI computing environment will also include experimental quantum computing platform, LUMI-IQ, designed for HPC+AI+QC workloads. This one-of-a-kind platform will open completely new horizons for scientific discovery and RDI, both for industry and fundamental science. LUMI-AI and LUMI-IQ will form the most advanced public quantum-accelerated HPC+AI research infrastructure in the world.
Goals of LUMI-IQ are:
- Set up a world-leading HPC+AI+QC infrastructure to serve all of Europe
- Explore a quantum advantage for AI, and utilize AI tools for quantum computing
- Accelerate Europe’s efforts to take a leading position in quantum computer hardware and software development
- Accelerate European academic leadership in quantum-accelerated AI
- Establish new high-value commercial activities
LUMI-IQ to be available at the end of 2027
- First system deployed in LUMI-IQ will be IQM Halocene H4 quantum computer, featuring a quantum processing unit (QPU) with 150 high-quality qubits. The first system is scheduled for delivery at the end of 2027.
- The delivered Halocene system, a first of its kind, is an advanced on-premises superconducting quantum computer, combining quantum error correction with high-quality NISQ-era qubits.
- The LUMI-IQ quantum computer will be upgraded during its lifetime, evolving towards early fault tolerant quantum computing. A series of upgrades are delivered in multiple phases, significantly increasing the platforms qubit count, error resilience and advanced quantum error correction capabilities.
- LUMI-IQ will incorporate modular quantum error correction stack, allowing users to develop and implement Quantum Error Correction (QEC) concepts on a world-leading system.
- LUMI-IQ bridges high-performance computing (HPC), AI, and emerging quantum technologies. As part of the LUMI AI Factory, LUMI-IQ extends the existing computing environment with quantum computing capabilities, enabling researchers and companies to combine HPC, AI, and quantum technologies to address some of the most complex scientific and industrial challenges, including problems beyond the reach of today’s conventional computing methods.
- LUMI-IQ will offer services to support the adoption of hybrid computing, including user support, consulting, training, software tools, development environments, and application-focused use cases. From launch, users will have access to a dedicated software library with practical examples for integrating quantum AI into existing workflows, making hybrid computing accessible to both experts and non-experts. Together, these services will help researchers and companies translate quantum technologies into new applications, innovations, and business opportunities, while strengthening Europe’s leadership in quantum technologies and AI.
