DAEDALUS supercomputer, implemented by the National Infrastructures for Research and Technology (GRNET S.A.), supervised by the Hellenic Ministry of Digital Governance and Artificial Intelligence, has been ranked significantly high in the internationally renowned TOP500 and Green500 lists, the two most recognized global rankings of supercomputing systems.
The latest editions of the TOP500 and Green500 rankings were published on Tuesday, 23 June 2026, during ISC 2026 in Hamburg, Germany, according to the relevant announcement of the European High Performance Computing Joint Undertaking (EuroHPC JU). DAEDALUS is ranked 31st in the TOP500 list and 23rd in the Green500 list, further strengthening Greece’s position on the global map of High-Performance Computing (HPC) and energy-efficient supercomputing.
DAEDALUS joins the strong presence of EuroHPC systems featured in the latest TOP500 and Green500 rankings, alongside European supercomputers such as JUPITER, LUMI, Leonardo, MareNostrum and Arrhenius, highlighting Europe’s contribution to both High-Performance Computing and sustainable, energy-efficient supercomputing.
With a measured performance of 85.69 petaflops in the TOP500 ranking, DAEDALUS becomes the most powerful computing system ever ranked in Greece to date. The system is based on Hewlett Packard Enterprise (HPE) architecture, featuring NVIDIA GH200 accelerators and direct liquid cooling technology, combining high computational performance with a strong focus on sustainability and operational efficiency.
DAEDALUS and its new Data Center is situated at the Lavrion Technological and Cultural Park of the National Technical University of Athens (NTUA), within the historic former Power Station building, a recognized monument of modern industrial heritage. The infrastructure has been designed with sustainability at its core, utilizing renewable energy sources and advanced cooling technologies aimed at reducing overall energy consumption.
About the TOP500 and Green500 Lists:
The TOP500 list ranks the 500 most powerful supercomputers in the world based on their measured computational performance using the internationally recognized LINPACK Benchmark. The ranking reflects the maximum processing speed at which these systems are capable of executing complex mathematical calculations.
The Green500 list ranks TOP500 systems according to their energy efficiency, measuring the computational performance delivered relative to the energy consumed. DAEDALUS’ presence in both rankings demonstrates its successful combination of high computational power and sustainable operation.
DAEDALUS represents a critical national infrastructure for supporting advanced applications in Artificial Intelligence, scientific research, big data analytics and innovation. Its computational capabilities will be leveraged across a wide range of domains, including personalized healthcare, climate research, public administration, cybersecurity, the Greek language and culture, amongst others.
At the same time, DAEDALUS will serve as the computational backbone of the Greek AI Factory, PHAROS, coordinated by GRNET within the framework of the European AI Factories network. PHAROS aims to foster a trustworthy and sustainable Artificial Intelligence ecosystem serving the public sector, the research community, startups and SMEs, with a particular focus on Language and Culture, Health and Sustainability.
The inclusion of DAEDALUS in both the TOP500 and Green500 lists marks a significant milestone for Greece, strengthening the country’s participation in the European and international ecosystems of High-Performance Computing, Artificial Intelligence and sustainable digital innovation.
The project is being implemented by GRNET S.A. within the framework of the National Recovery and Resilience Plan “Greece 2.0”, with funding from the European Union – NextGenerationEU and the EuroHPC Joint Undertaking (EuroHPC JU). DAEDALUS is expected to become operational during 2026 and will be made available to the Greek and European research, academic and scientific communities, as well as industry and the public sector.
