Get to know the computing infrastructure
By building on the LUMI supercomputer, adding an AI-optimised system, LUMI-AI, and exploring quantum computing for AI workloads on the LUMI-IQ platform, we provide a world-class environment for innovation.
LUMI supercomputer
In the beginning, the LUMI AI Factory will leverage the power of the LUMI supercomputer. The LUMI supercomputer comes with numerous benefits and tangible impacts, making the entire LUMI system stand out from many other data centers.
LUMI is Europe’s top-tier supercomputer owned by the EuroHPC Joint Undertaking. It is hosted by the 11-country LUMI consortium and is located in CSC’s data center in Kajaani, Finland.
The LUMI consortium countries of Finland, Belgium, Czech Republic, Denmark, Estonia, Iceland, the Netherlands, Norway, Poland, Sweden and Switzerland provide a high-quality, cost-efficient and environmentally sustainable HPC ecosystem based on true European collaboration. As part of the EuroHPC JU, LUMI delivers world-class computational power for research and innovation across Europe, supporting AI and big data research with advanced GPU nodes, cloud services, and object storage.

LUMI – Europe’s top-tier supercomputer
- One of the world’s fastest computer systems. The sustained computing power is 380 petaflops (HPL, High-Performance Linpack).
- Computing power equivalent to the combined performance of 1.5 million modern laptops.
- Achieves its high performance with a large number of nodes with accelerators (2978 GPU nodes, a total of 11 912 AMD GPU processors). The system is complemented by a CPU only partition, cloud services and a large object storage solution.
- LUMI is also one of the world’s most powerful AI platforms for science.
- LUMI features one of the most mature integrations of quantum processors to high-performance computing.
- 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.
- Over 3000 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% hydropower.
- 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 be the new AI-focused supercomputer leveraging a large, accelerated partition utilising next-generation GPUs offering flexibility in supporting a wide range of compute workloads, from training to inference and classical simulations. It will be located at CSC’s data center in Kajaani, Finland, home also to the current LUMI system.
LUMI-AI system architecture
Built using the latest-generation GPUs and CPUs with the best cost-performance ratio at the time of installation, LUMI-AI will be one of the fastest and most advanced public supercomputer systems globally. The system will be supplemented by several supporting compute and storage resources, maximizing its overall value. One of its key differentiator will be the multi-tenancy approach, designed to meet the needs of AI communities, coupled with a pronounced role for API-based access.
The procurement process for the LUMI-AI system is ongoing. Below you will find design phase images of the system’s architecture, software-defined clusters and storage solution.



LUMI-IQ
The LUMI-AI computing environment will also leverage a one-of-a-kind experimental quantum computing platform, LUMI-IQ, designed for HPC+AI+QC workloads. This one-of-a-kind platform will open completely new horizons for research. 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
- Provide a quantum advantage for AI
- 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

The proposed solution will start with a base installation of a high-performant quantum computer. Along with the first installation, the entire hardware stack, including for example possible cryostats and control electronics will be set up, resulting in a world leading quantum computing experimental platform based on European technology. The whole system will be designed to enable upgrades of the central computational component of the platform, that is, the quantum processing unit, QPU.
The initial installation will be upgraded throughout the project. The upgrades will increase the capacity and capability of the platform through both hardware and software improvements. The first upgrade will enable parallel quantum computing, and future upgrades will introduce quantum error correction, higher number and quality of qubits, transitioning towards fault-tolerant quantum computing and logical qubits.
