Greece has brought online DAEDALUS, its most capable supercomputer to date. Debuting in the June 2026 TOP500 list, the machine claimed 31st position among the world's fastest systems and 23rd in the Green500 efficiency rankings.
The inauguration took place on 19 October at the Lavrion Technological Cultural Park, part of the National Technical University of Athens. Greek Prime Minister Kyriakos Mitsotakis attended, alongside Thomas Skordas, Deputy Director-General at the European Commission's Directorate-General for Communications Networks, Content and Technology (DG CONNECT); Minister Dimitris Papastergiou; Afrodite Sevasti and Evangelos Floros, Head of Infrastructure unit at the EuroHPC JU. The event also included Professor Ioannis Hatzigeorgiou, Professor Emeritus Stefanos Kollias and Professor Nektarios Koziris.
Greece's journey in technology, from lagging behind to being at the forefront, particularly in the field of Artificial Intelligence, has indeed been and continues to be extremely exciting. I would like to thank everyone who worked to make this project a reality. I can see the emotion in many people's eyes, because I know how hard you all worked in order for us to reach this point today, where, as a country, we have one of the world's most powerful supercomputers, while at the same time having it installed in a building of such great historical and cultural significance. We are building a 'bridge' from the Second Industrial Revolution, from the early 20th century, when we generated electricity in this space, to having installed a supercomputer with exceptional capabilities in the very same building. Now we are taking the next step: making this incredible computing power available to Greek researchers, the Greek business community, start-ups, and larger enterprises alike. Wishing all the good fortune ahead for DAEDALUS operations
Kyriakos Mitsotakis, Prime Minister of Greece
It is a great honour to be in Lavrion today for the inauguration of the 'DAEDALUS' supercomputer. At a time when technological sovereignty and competitiveness are crucial, Europe is investing strategically in advanced computing. With EUR 36 million in support, 'DAEDALUS' strengthens Greece's position at the heart of the digital future. Greece is among the first seven European countries to host an AI Factory, placing it firmly on the global supercomputing map. As the computing infrastructure of the PHAROS AI Factory, it will turn research into tangible social and economic impact by providing world-class computing power to Greek talent. Together, we are ensuring that Greece and Europe help shape the future.

I am delighted to welcome another powerful supercomputer to the EuroHPC ecosystem, strengthening Europe's supercomputing capabilities and technological sovereignty. DAEDALUS will provide European researchers, industry and innovators with access to advanced computing resources focussing on areas such as healthcare, public services, energy, and the environment.

System specifications and design
The machine delivers sustained performance of 85.69 petaflops—roughly 86 quadrillion calculations per second—with peak capacity reaching 115 petaflops. Hewlett Packard Enterprise constructed the system using more than 2,000 NVIDIA GH200 Grace Hopper Superchips, incorporating direct liquid cooling to optimise energy consumption.
Total acquisition cost stands at EUR 36 million. The EuroHPC JU contributed 35 per cent of this sum, while Greece's National Recovery and Resilience Plan 'Greece 2.0', supported by the European Union's NextGenerationEU funding, supplied the remaining 65 per cent. The DAEDALUS consortium extends beyond Greece to include Cyprus, Montenegro and North Macedonia, demonstrating regional collaboration on computing infrastructure.
Location and operations
The supercomputer occupies a newly constructed data centre at the Lavrion Technological Cultural Park within a former power station building that forms part of Greece's industrial heritage. The facility draws power from renewable energy sources. GRNET S.A., the National Infrastructures for Research and Technology, manages and operates the system.
DAEDALUS will support applications spanning artificial intelligence, medicine, climate and meteorological research, engineering, big data analytics, smart transport systems and cybersecurity.
Integration with PHAROS AI Factory
The supercomputer serves as the computational foundation for PHAROS, Greece's AI Factory operating within the EuroHPC JU's European network of AI Factories. PHAROS concentrates on health, sustainability, language and culture, developing innovative AI solutions and reinforcing the broader European AI ecosystem.
The pairing of DAEDALUS and PHAROS creates pathways for AI development, enabling European innovators to build, validate and expand AI applications.
EuroHPC JU context
The EuroHPC JU functions as a joint legal and funding entity uniting the European Union with participating member states to coordinate supercomputing efforts and combine resources, positioning Europe as a global supercomputing leader.
The organisation has already procured 12 supercomputers distributed throughout Europe. Researchers and organisations across the public and private sectors can access EuroHPC systems through EuroHPC Access Calls, regardless of their location within Europe, to advance scientific and industrial applications of continental importance.
Beyond supercomputing, the EuroHPC JU oversees 19 AI Factories across Europe, complemented by 13 AI Factory Antennas providing free, tailored assistance to small and medium-sized enterprises and startups. The organisation is also deploying a European Quantum Computing infrastructure that combines various European quantum technologies with existing supercomputers.
The EuroHPC JU funds research and innovation initiatives aimed at constructing a complete European supercomputing supply chain, encompassing processors, software, applications and expertise development. Following the recent adoption of Council Regulation (EU) 2026/150, the EuroHPC JU's remit has expanded to include deployment of AI Gigafactories and advancement of quantum technologies.
