MeluXina is the European Union's greenest supercomputer

Published on

The EuroHPC Joint Undertaking petascale supercomputer MeluXina, located in Luxembourg, has been named by the Green500 as the greenest supercomputer in the European Union and the fourth greenest in the world.

The Green500 list, compiled bi-annually by supercomputer ranking organisation TOP500, ranks the top 500 most powerful supercomputers in the world by their energy efficiency.

MeluXina and all EuroHPC JU systems are water cooled, removing the requirement of high operational costs of air-cooled systems and in parallel reducing the energy footprint. MeluXina relies on the latest AMD EPYC processors and NVidia A100 GPUs to achieve a remarkable efficiency in terms of performance to power consumption ratio (26.957 gigaflops/watt).

Another EuroHPC JU machine also performed well on the list released this week, with petascale supercomputer Karolina in the Czech Republic ranking 7th in the EU and 15th globally for energy efficiency.

As well as placing at the top of the Green500, MeluXina is ranked as the 10th most powerful supercomputer in the EU and 37th globally, according to the TOP500 ranking of the world’s most powerful supercomputers.

All four EuroHPC JU supercomputers delivered so far have been placed in the top 500 list for the first time. Hot on MeluXina’s heels is Karolina, placed at 20th in the EU and 70th globally; Discoverer, located in Bulgaria, ranked at 27th in the EU and 92nd globally; and Slovenian machine Vega at 32nd in the EU and 107th globally.

Anders Dam Jensen, EuroHPC Joint Undertaking Executive Director, said:

“We are proud to lead the way in European green HPC technology. MeluXina confirms that the next generation of supercomputers will need to harness energy efficient solutions and contribute to environmental targets while providing world-class supercomputing capabilities.

“Furthermore, MeluXina like all other EuroHPC JU supercomputers will be accessible to European researchers, SMEs, and organisations working to solve key environmental and climate issues in the coming years. Green and sustainable technologies are a priority for the Joint Undertaking, as part of the European Green Deal’s aim to make Europe climate neutral by 2050.”

 

Valentin Plugaru, Chief Technology Officer of LuxProvide, said:

“We are delighted with the results, they show the fruit of years of planning and now implementation of the vision of what MeluXina should be. The system has been built on an efficient platform and is meant to serve a large variety of complex, data-driven computational workloads.

“Based on the Modular Supercomputing Architecture, its forward-looking design responds to the convergence of simulation, modelling, data analytics and AI, and enables simulation driven by predictive analytics. MeluXina will provide a robust platform for science and industry for years to come.”

 

Background

The TOP500 list is compiled twice per year in June and November and ranks the world’s most powerful supercomputers by their performance on the LINPACK Benchmark.

The Green500 list is compiled twice per year in June and November and ranks the world’s supercomputers for their energy efficiency.

The EuroHPC JU’s objective is to foster better science and enhance innovation in Europe by providing access to cutting-edge High Performance Computing infrastructures and services to a wide range of users from the research and scientific community, as well as industry and the public sector.

The company Atos was selected following the call for tender launched in January 2020 for the acquisition, delivery, installation and maintenance of a Petascale supercomputer located in LuxProvide's data center in Bissen, Luxembourg.

Four other petascale supercomputers have been procured under the EuroHPC Joint Undertaking:

Furthermore, two EuroHPC pre-exascale supercomputers have been procured and will complement the petascale machines:
