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-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 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 – experimental quantum computing platform

  • 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 in 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 computing platform 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.
