LUMI again among the fastest and greenest supercomputers in the world

EuroHPC Joint Undertaking’s LUMI supercomputer reached the third spot on the new Top500 list of world’s fastest supercomputers released at the SC22 conference in Dallas, USA, on 14 November 2022. LUMI reached a measured High-Performance Linpack (HPL) performance of 309 petaflops on this biannual list. This makes LUMI the fastest supercomputer in Europe. 

The LUMI supercomputer reached the seventh spot on the new Green500 list which biannually ranks supercomputers from the Top500 list in terms of energy efficiency. The GFlops/Watts ratio for LUMI is 51.38, making it one of the greenest supercomputers in the world.

LUMI is a unique endeavour thanks to its scale, sustainability and pan-European nature, hosted by a consortium of ten countries. Kimmo Koski, Managing Director of CSC – IT Center for Science, Finland, on behalf of the LUMI consortium, comments: "To be able to reach the very top spots of the Top500 ranking is a remarkable achievement and proves the power of European cooperation. By joining forces, the LUMI consortium, in cooperation with EuroHPC JU, has managed to acquire the kind of state-of-the-art device to support its RDI efforts none of us in the ten consortium countries could have achieved on our own."

"We are delighted about LUMI’s position in the ranking, and we are even more excited about seeing the societal impact that this extremely powerful platform will have, by making it possible to tackle next-level computational challenges in all fields of research, involving larger datasets than most European researchers have ever been able to use before. LUMI will advance digitalization across the whole society," Koski continues. 

"I am very pleased to see LUMI on the Top500 podium. With this remarkable machine, we can really see the results of European collaboration at work. LUMI's exceptional technologies will bolster European competitiveness and innovation, and further support Europe’s digital sovereignty," says Anders Dam Jensen, Executive Director of the EuroHPC Joint Undertaking.

The LUMI system is supplied by Hewlett Packard Enterprise (HPE), based on an HPE Cray EX supercomputer. 

CSC’s data centre in Kajaani, Finland, where LUMI is placed, is one of the world’s most eco-efficient data centres. LUMI uses 100% carbon-free hydroelectric energy for its operations, and its waste heat can be reused to heat the surrounding houses in city of Kajaani. Thanks to the cool climate of the region very little energy is needed to keep the supercomputer cool.
