On the international TOP500 and Green500 lists, the two most widely recognized global supercomputer rankings, “DAIDALOS”—implemented by the National Network for Technology and Research Infrastructure (EDYTE S.A. - GRNET), an agency of the Ministry of Digital Governance and Artificial Intelligence.
The TOP500 and Green500 lists were published in Hamburg, Germany, as part of ISC 2026, according to a related announcement by the European High-Performance Computing Joint Undertaking (EuroHPC JU).
According to the ministry’s announcement, “DAIDALOS” ranked 31st on the TOP500 list and 23rd on the Green500 list, strengthening Greece’s presence on the international map of high-performance computing and energy-efficient supercomputing. It should be noted that the supercomputer to be installed in Lavrio ranks among the most powerful systems in the EuroHPC network, alongside other European supercomputers such as Germany’s JUPITER, Finland’s LUMI, Italy’s Leonardo, and Sweden’s Arrhenius.
It should be noted that the “DAIDALOS” system is based on Hewlett Packard Enterprise (HPE) architecture with NVIDIA GH200 accelerators and direct liquid cooling technology, and its measured performance is 85.69 petaflops. This makes it not only the most powerful computing system in Greece to date, but also marks the country’s first appearance on such lists.
“DAIDALOS” and the new Data Center will be installed at the Lavrio Technology and Cultural Park of the National Technical University of Athens, in the historic building of the former Power Station, a recognized monument of modern industrial heritage. The infrastructure has been designed with sustainability in mind, utilizing renewable energy sources and advanced cooling systems, with the aim of reducing energy consumption.
The project is being implemented by EDYTE S.A. – GRNET, as part of the National Recovery and Resilience Plan “Greece 2.0,” with funding from the European Union – NextGenerationEU and the EuroHPC Joint Undertaking (JU). “DAIDALOS” is expected to become operational in the near future, serving the Greek and European research, academic, and scientific communities, as well as industry and the public sector.
The TOP500 & GREEN500 Lists
The TOP500 list ranks the 500 most powerful supercomputers in the world based on their measured computational performance on the internationally recognized LINPACK Benchmark. It reflects the maximum relative speed at which supercomputing systems perform complex mathematical calculations.
The Green500 list ranks the TOP500 systems based on their energy efficiency—that is, the computational power they produce relative to the energy they consume.
The presence of “DAIDALOS” on both lists highlights its combination of high computing power and sustainable operation.
“DAIDALOS” and Data Utilization
“DAIDALOS” is a critical infrastructure for supporting advanced applications in artificial intelligence, scientific research, big data analysis, and innovation. Its computing power will be harnessed in fields such as personalized healthcare, climate research, public administration, cybersecurity, the Greek language, and culture, among others.
At the same time, it will serve as the computational core of the national “PHAROS” Artificial Intelligence Factory, which is being developed as part of the European AI Factories network, with EDYTE S.A. — GRNET, an agency of the Ministry of Digital Governance, coordinating the project, and PHAROS S.A., a subsidiary of the Superfund and the Ministry of Digital Governance and Artificial Intelligence, serving as the project’s business arm.
The initiative is part of the broader framework of policies and actions for Artificial Intelligence in the country, under the coordination of the Special Secretariat for Artificial Intelligence and Data Governance, contributing to the strengthening of national capabilities in critical technologies and the European Union’s digital sovereignty.
