The “GRNET S.A. Grant for the development of a new national High Performance Computing (HPC) system” Project includes the development of a new system through the procurement of new hardware and infrastructure. The new high-performance supercomputer called “DAEDALUS” is installed in the Lavrion Technological Cultural Park of the National Technical University of Athens, inside the “Former Electrical Station” building, an industrial heritage monument, covering an area of 1.500sq.m.
GRNET is responsible for the development and operation of the new high-performance supercomputer DAEDALUS. GRNET participates in multiple pan-European HPC initiatives and projects, mainly through the development and support of the infrastructure of ARIS supercomputer (Advanced Research Information System). DAEDALUS has a computational power of >85 Petaflops, 120 times greater than the ARIS system, performing eighty-five million billion mobile subspace operations per second (i.e. eighty-five quadrillion – 89,000,000,000,000,000). In addition, it will be hybrid, featuring both high-density central processing units (CPUs) and accelerator units.
This performance places DAEDALUS among the world’s leading supercomputing systems. According to the June 2026 TOP500 and GREEN500 rankings, published on 23 June 2026, DAEDALUS ranks 31st in the TOP500 and 23rd in the GREEN500. With a measured performance of 85.69 petaflops, DAEDALUS is the most powerful computing system ever ranked in Greece, strengthening the country’s position on the global High-Performance Computing and scientific research landscape. At the same time, it provides significant opportunities for scientific and technological advancement, supporting a wide range of Greek and European users from the scientific and academic communities, industry, and the public sector. Its computing capabilities will enable the development of new applications across a broad range of research fields, including Computational Chemistry, Physics, Biology, Biomedicine, Meteorology, Artificial Intelligence, and large-scale data analysis.
DAEDALUS’s installation in Lavrio has taken into consideration environmentally sustainable design principles. DAEDALUS is powered by renewable energy systems, while modern cooling systems are being used in order to keep energy costs low. The air conditioning solution is adapted to the weather of Lavrio area (ambient temperatures and relative humidity during the year), taking advantage of the natural environment and is expected to save a significant percentage of the required operational energy (due to cooling), in the range of 40%-50%.
The Project is a derivative from the Digital Transformation Strategy 2020-2025, called: The Digital “Bible” of the Ministry of Digital Governance and Artificial Intelligence is implemented within the framework of the National Recovery and Resilience Plan “Greece 2.0” with the funding of the European Union - NextGenerationEU. At the same time, the Initiative of the Joint Undertaking “European High Performance Computing Joint Undertaking - EuroHPC JU” announced that Greece has been selected as one of the five European countries that will host the leading mid-range HPC supercomputers (pre-exascale or petascale HPC). The EuroHPC JU Joint Undertaking allows the European Union and its participating countries to coordinate their efforts and share resources, in order to develop a world-class supercomputing infrastructure and a competitive innovation ecosystem in Europe.
GRNET has over the last two decades been strategically responsible to develop and support major science and technology projects in Greece, as well as support the wider region of Southeast Europe, by coordinating a number of major infrastructure projects. In this context, Cyprus, North Macedonia and Montenegro, as members of the EuroHPC JU Joint Undertaking, have joined the operation consortium of the new supercomputer DAEDALUS. Therefore, these countries will form part of the support consortium of DAEDALUS users and will receive equivalent hours of usage on the new supercomputer.
The procurement cost of DAEDALUS is 36 million euros and is covered up to 35% by the European Initiative of the EuroHPC JU & 65% of the Recovery and Resilience Fund (RRF) “Greece 2.0” receiving funds from the European Union - NextGenerationEU. The total cost of this project is estimated more than 50 million euros.
