EuroHPC supercomputers achieve top rankings on TOP500 and Green500 lists once again

All operational petascale EuroHPC systems have ranked once again among the world’s most powerful & energy efficient supercomputers, while LUMI remains one of the greenest supercomputers in the world.

The TOP500 list ranks the world’s most powerful supercomputers by their performance on the LINPACK Benchmark while the Green500 list ranks the top 500 most powerful supercomputers in the world by measuring their energy efficiency features. The TOP500 and the Green500 lists are compiled twice a year in June and November. The lastest rankings have been released earlier this week at the SC22 conference in Dallas, United States.

LUMI: one of the greenest supercomputers in the world

The EuroHPC pre-exascale supercomputer LUMI, located in Finland and hosted by CSC – IT Center for Science, is not only the most powerful supercomputer in Europe but also one of the greenest in the world, reaching 7th place on the new Green500 list.

LUMI, like all EuroHPC JU systems, is water cooled. As such it removes the requirement of high operational costs of air-cooled systems and in parallel reduces the energy footprint of the system.

What makes the energy-efficiency of LUMI so unique is the fact that LUMI uses 100% carbon-free hydroelectric energy for its operations, and its waste heat is reused to heat up the surrounding houses in city of Kajaani. In addition thanks to the cool climate of the region very little energy is needed to keep the supercomputer cool.

Anders Dam Jensen, Executive Director of the European High Performance Computing Joint Undertaking (EuroHPC JU), commented:

“I am not only pleased with LUMI’s achievements for its computing power, but also its result on the Green500 list. It is ever more important to consider energy efficiency and sustainability in supercomputing, and I am very proud that LUMI can be an example of eco-conscious computing allied with top-of-the-range technology and world-leading supercomputing power.“

Kimmo Koski, Managing Director of CSC – IT Center for Science, Finland, on behalf of the LUMI consortium added:

“Excellent energy efficiency has been a key priority for the LUMI consortium since the very beginning of the LUMI project. We are very proud of the small carbon footprint of our supercomputer and we are also expecting LUMI to have a sizeable carbon handprint, i.e., positive impact on climate through RDI projects aiming to create new knowledge and innovation for advancing climate-friendly public policies and business operations”

A fleet of world-class green supercomputers

All operational EuroHPC petascale supercomputers,  MeluXinaVegaDiscoverer, and Karolina have also ranked in the top 140 of the world’s fastest supercomputers, according to the latest TOP500 ranking.

In the Green500 list, four EuroHPC supercomputers, LUMI in Finland, Leonardo in Italy, Karolina in Czechia and MeluXina in Luxembourg, rank among the top 25 greenest supercomputers in the world.

These rankings are testimonies to the work that the EuroHPC JU is doing to achieve its mission of developing a world-class supercomputing infrastructure in Europe while promoting green and sustainable technologies.


Background

The EuroHPC JU is a legal and funding entity created in 2018 to enable the European Union and EuroHPC participating countries to coordinate their efforts and pool their resources with the objective of making Europe a world leader in supercomputing. The mission of the EuroHPC JU is:

  • to develop, deploy, extend and maintain in the EU a federated, secure hyperconnected supercomputing, quantum computing, service and data infrastructure ecosystem;
  • to support the development and uptake of demand-oriented and user-driven innovative and competitive supercomputing and quantum computing systems based on a supply chain that will ensure the availability of components, technologies and knowledge;
  • and, to widen the use of that supercomputing and quantum computing infrastructure to a large number of public and private users.

To date the EuroHPC JU has already procured eight supercomputers, located across Europe: LUMI in Finland, LEONARDO in Italy, Vega in Slovenia, MeluXina in Luxembourg, Discoverer in Bulgaria, Karolina in the Czechia, MareNostrum5in Spain, and Deucalion in Portugal.
