DAEDALUS inaugurated: Greece’s new national supercomputer at Lavrio, with 85.69 petaflops, ranks 31st in the world

DAEDALUS, Greece’s new national supercomputer, was inaugurated on Monday, October 19 at Lavrio in the presence of Prime Minister Kyriakos Mitsotakis. With a measured computing power of 85.69 petaflops, roughly 85.69 quadrillion floating-point operations per second, the system ranks 31st in the world and opens new possibilities for developing artificial intelligence applications in Greece. It is one of the systems of the EU’s EuroHPC Joint Undertaking for high-performance computing, a mid-range supercomputer installed in Attica.

Cost and technology

The project costs 58.9 million euros in total, funded by the Recovery and Resilience Facility and EuroHPC. Hewlett Packard Enterprise supplied and installed the computing equipment with a budget of 41 million euros, while Mainsys carried out the electromechanical installations and the data centre for 17.9 million euros, figures that include VAT. Management and technical operation have been taken on by GRNET, which was also the implementing body.

DAEDALUS is based on Nvidia Grace Hopper GH200 technology with liquid cooling, and in the June 2026 Green500 ranking it came 23rd in the world for energy efficiency.

Who will use it

The supercomputer is housed in the historic building of the former power station in the Lavrio Technological and Cultural Park, run under the responsibility of the National Technical University of Athens. It will be used by universities, research centres, businesses, public bodies and health organisations to train advanced AI models, process large volumes of data and run complex simulations. A key advantage is that sensitive or confidential data can be processed inside the country, which matters for medical research, public administration and any sector with strict data rules.

A central role in making DAEDALUS available to the market will be played by the Pharos AI Factory, Greece’s “AI factory”, which was among the first seven such initiatives selected by the EU. Wider services for businesses are planned for March 2027, after technical testing. Start-ups and small and medium-sized enterprises are expected to have free access within state aid rules, while charging by usage time is being considered for larger companies.

DAEDALUS adds to Greece’s high-technology infrastructure, such as the satellite control centre of Planetek Hellas, at a time when Greek defence is also turning to autonomous systems like the unmanned vessel Pyrpolitis.
