MeluXina-AI is the supercomputer behind the Luxembourg AI Factory: 1.008 NVIDIA GPUs on 252 nodes, split between data centres in Bissen and Bettembourg, for 80 Mio. EUR. According to the government, it opens to users from 2027.

The EuroHPC Joint Undertaking signed the supply contract with E4 Computer Engineering on 22.07.2026, and LuxProvide will operate the system. Until then, AI workloads in Luxembourg run on the existing MeluXina.

What is MeluXina-AI?

According to the EuroHPC JU announcement of 22.07.2026, MeluXina-AI is an AI-optimised supercomputer for training, testing and preparing advanced AI models for deployment. It is built on Dell Technologies servers with liquid cooled NVIDIA GB200 NVL4 systems from the Blackwell generation: 252 nodes with 1.008 GPUs in total, so four per node. Its estimated AI peak performance is above 20 exaflops, backed by a file system serving both AI and HPC workloads.

The software stack is designed to deliver GPU-as-a-Service to multiple tenants in isolated, container based environments, with bridges to external data platforms, cloud providers and other AI Factories. LuxProvide says the system will run in LuxConnect's Tier IV data centres under LuxProvide's ISO 27001 framework.

Who builds it, who owns it and what does it cost?

The contractor is not Dell but the Italian systems integrator E4 Computer Engineering, selected after a tender launched in February 2026. Dell Technologies takes part as a subcontractor. According to the tender notice, MeluXina-AI will be owned by the EuroHPC JU and operated by LuxProvide, Luxembourg's national supercomputing centre.

The 80 Mio. EUR cover acquisition, delivery, installation and maintenance, with the EuroHPC JU paying 50 % through the Digital Europe Programme. That is not the full bill. Back in December 2024 the government put the total cost at 112 Mio. EUR, including 32 Mio. EUR for hosting and operation over five years. On top come 14 Mio. EUR to run the AI Factory for three years, which is why the Luxembourg AI Factory cites a total investment of 126 Mio. EUR.

How far along is the project?

The EuroHPC JU said installation was expected to start in autumn 2026. In April 2026 the launch was still planned for the end of 2026. In their answer to parliamentary question No. 4551, dated 02.09.2026, ministers Lex Delles and Stéphanie Obertin wrote instead that the capacity would be available "from 2027". As of 12.11.2026 we found no public update from the EuroHPC JU, LuxProvide or the government on the state of the installation.

The same answer explains why the more than 2.100 accelerators announced in December 2024 became 1.008 GPUs: the chosen chips are newer and far more powerful, but also much more expensive. According to the ministers, the contractor guarantees a machine ten times more powerful than today's MeluXina for training AI models and forty times more powerful for inference.

How does it relate to the existing MeluXina?

The existing MeluXina has been running in Bissen since June 2021, with 18 petaflops and 800 GPU accelerators, NVIDIA A100 according to its documentation. It is a general purpose supercomputer for simulation, data analytics and AI. According to the parliamentary answer, its average utilisation is above 70 %, with more than 4.600 users and over 1.550 projects. Over three years, public research used about 90 % of the national capacity and private companies about 10 %.

MeluXina-AI does not replace it but adds a specialised AI machine. Half of MeluXina-AI's capacity is reserved for Luxembourg and the other half for the EuroHPC network.

Who can use the Luxembourg AI Factory?

The support services are already running. According to Luxinnovation, the AI Factory offers 66 services in seven categories and had supported more than 150 companies by April 2026, mostly SMEs. Luxinnovation is the single point of entry. The consortium is coordinated by LuxProvide and also includes LNDS, the University of Luxembourg and LIST.

For computing time there are several routes:

  • EuroHPC access modes: Playground for newcomers, with access within two working days; Fast Lane for up to 50.000 GPU hours over at most three months; Large Scale for more than 50.000 GPU hours, with two cut-offs a month, the next on 13.11.2026 and 30.11.2026. These industrial access modes are free for SMEs and start-ups, while research applies through "AI for Science".
  • LuxProvide: INITIATE gives start-ups founded within the last five years up to six months of free computing time on MeluXina. CASHBACK80 refunds SMEs up to 80 % of usage costs through a state aid application to the Ministry of the Economy.
  • Funding: for a first AI assessment in your own company, see our guide to the SME Packages AI.

Prices for MeluXina-AI's national capacity have not been set yet, the government says, and companies will in principle pay market rates. LuxProvide urges users on LinkedIn not to wait for MeluXina-AI and to run AI workloads on MeluXina now.

What role does Luxembourg play in the EU network?

Luxembourg was picked in December 2024 as one of the first seven AI Factories. According to the European Commission, the EU is now setting up 19 AI Factories and 13 Antennas, with at least nine new AI-optimised supercomputers. One level up are the AI Gigafactories: the tender launched on 30.07.2026 targets up to seven sites with more than 100.000 AI processors each, backed by up to 10 Mrd. EUR in public funding. MeluXina-AI is far smaller, but is aimed squarely at access for SMEs and start-ups. For where the country stands overall, see the IMD ranking.

How dependent is the project on Nvidia?

Both Luxembourg systems run on NVIDIA GPUs. Nvidia today announced the resignation of CEO Jensen Huang. The MeluXina-AI contract has been signed with E4 and the hardware is specified. As of 12.11.2026 we found no statement from the EuroHPC JU or LuxProvide on any possible consequences.

What does this mean for companies in Luxembourg?

MeluXina-AI is funded, ordered and specified, and is due to open to users from 2027. Until then, the AI Factory's support services and MeluXina are the way in. Companies that want to test AI models should also keep an eye on the new AI regulatory sandboxes.

Questions and answers

When can MeluXina-AI be used?
From 2027, according to the answer by ministers Delles and Obertin of 02.09.2026. In April 2026 the end of 2026 was still mentioned.
Who is building MeluXina-AI?
The EuroHPC JU contractor is E4 Computer Engineering. Dell Technologies supplies the servers as subcontractor and the GPUs come from NVIDIA.
What does access cost?
Prices for the national capacity have not been set. Through EuroHPC access modes, computing time is free for SMEs and start-ups, and LuxProvide offers INITIATE and CASHBACK80.
