Nvidia unveils 35 AI supercomputers across Europe

NVIDIA ↘ 1.39% announced Monday at ISC High Performance 2026 in Hamburg, Germany, that a record 35 AI supercomputers are under development across Europe, representing the continent's largest one-year expansion in supercomputing infrastructure.Investing.com

The systems span national supercomputing centers, AI factories, and academic research institutions across 23 countries and will serve more than 3 million researchers. Built on NVIDIA's Blackwell and Hopper platforms, the buildout accounts for over 90% of Europe's AI factory deployment, with 800 AI exaflops deployed or announced since last year.Investing.com

Key Installations

Among the headline projects, Barcelona Supercomputing Center will expand its MareNostrum 5 system with NVIDIA GB300 NVL72 and GB200 NVL4 systems, delivering approximately 20 exaflops of AI training and 33 exaflops of AI inference performance. Italy's IT4LIA will feature over 8,000 GPUs delivering 82 exaflops of AI training performance, supporting applications in agritech, cybersecurity, meteorology, and manufacturing.Investing.com

Germany's first AI factory, HammerHAI, hosted at the High-Performance Computing Center Stuttgart, will deploy over 850 GPUs based on liquid-cooled NVIDIA GB200 NVL4 architecture. The EuroHPC Joint Undertaking signed the deployment contract with HPE in March, with the system expected to become operational in the second half of 2026. BavariaAI's Blue Swan will bring 1,000 GPUs to FAU Erlangen and LRZ supercomputing centers.TechNews 科技新報+2

Clean Energy and Quantum Ambitions

Beyond raw computing power, the expansion is fueling applied research in decarbonization and quantum computing. Siemens Energy is using NVIDIA technologies to develop hydrogen-capable gas turbine burners, reducing simulation times by up to 77%. Barcelona Supercomputing Center, CINECA, Fraunhofer, and Jülich Supercomputing Centre are integrating quantum processors with GPU systems using the CUDA-Q platform.Investing.com

The announcement builds on NVIDIA's growing footprint in European scientific computing. At last year's ISC, the company revealed that the JUPITER supercomputer at the Jülich Supercomputing Centre — powered by nearly 24,000 GH200 Grace Hopper Superchips — had become Europe's fastest system and was on track to become the continent's first exascale machine. NVIDIA also unveiled on Monday its new Vera Rubin platform for scientific computing, delivering over 7 exaflops of AI performance in a single rack-scale system.investor.nvidia.com+1

The 35-system deployment underscores Europe's accelerating investment in sovereign AI infrastructure at a time of intensifying global competition in supercomputing.
