Lenovo, the technology company, has recently announced that its General Purpose Partition (GPP) of the MareNostrum 5 supercomputer has been classified as the top x86 general-purpose cluster on the prestigious TOP500 list. MareNostrum 5, which was inaugurated at the Barcelona Supercomputing Center, is a pre-exascale supercomputer built for the European High Performance Computing Joint Undertaking (EuroHPC JU). This powerful machine will play a crucial role in advancing Europe’s supercomputing capabilities and accelerating artificial intelligence (AI) research.

MareNostrum 5 is designed to handle a wide range of complex applications, from climate research to material science, surpassing the capabilities of cloud computing. With exceptional performance, the GPP cluster part of MareNostrum 5 will achieve an impressive 40.1 Rmax PFlop/s while consuming an efficient power of 5.7MW. The system incorporates Lenovo’s Neptune direct water-cooling technology and is powered by 6400 Lenovo ThinkSystem SD650 V3 systems integrated with the latest 4th Gen Intel Xeon Scalable processors.

Lenovo’s HPC infrastructure, built on its award-winning Neptune Liquid Cooling technology, has enabled the creation of the largest General-Purpose Partition in the world. Ranked at #19 overall on the TOP500 list, this partition is specifically designed to solve complex scientific problems by allowing resources to be shared and multiple tasks or programs to run simultaneously. This flexibility and improved efficiency enhance productivity by enabling different users or projects to access the system simultaneously based on their specific needs.

Sergi Girona, Operations Director at Barcelona Supercomputing Center, expressed pride in the joint work with Lenovo and highlighted the significance of MareNostrum 5 in addressing major global challenges in the digital era. The supercomputer’s partitioning and accelerated capabilities make it one of the most heterogeneous high-performance systems, enabling breakthroughs in climate change research, personalized medicine, and energy solutions. Girona emphasized that this infrastructure will be instrumental in advancing Europe’s digital strategy and fostering a more resilient and sovereign Europe.

Noam Rosen, Director of HPC and AI EMEA at Lenovo, commended Europe’s commitment to technological excellence and Lenovo’s support through the MareNostrum 5 pre-exascale system. Manufactured entirely in Europe, this supercomputer exemplifies Europe’s drive for technological leadership and Lenovo’s dedication to advancing scientific research. The MareNostrum 5 system is poised to accelerate scientific discovery and empower researchers to tackle a wide range of challenges. Lenovo is excited about supporting the scientific community and contributing to the Barcelona Supercomputing Center and EuroHPC’s leadership in driving HPC innovation across Europe.

It is worth noting that the HPC servers provided by Lenovo for MareNostrum 5 were manufactured at its state-of-the-art facility in Budapest, Hungary. This facility, opened in 2022, has played a crucial role in serving customers throughout Europe, the Middle East, and Africa with their server infrastructure and high-end PC workstation needs. Lenovo’s close collaboration with European customers and improved local visibility of supply chains has resulted in reduced CO2 emissions on shipments by over 90%. Lenovo has also partnered with prestigious institutions like the Barcelona Supercomputing Center, Leibniz Supercomputing Center, and SURF in the Netherlands to advance research and development capabilities.

Lenovo’s dominance in the supercomputing arena is evident in its impressive performance on both the TOP500 and Green500 lists. With 169 systems on the TOP500 list, Lenovo retains its number one position in systems share, solidifying its status as the leading provider of supercomputers worldwide. Additionally, Lenovo’s ThinkSystem SR670 V2 powers the Flatiron Institute’s Henri system, which holds the top spot on the Green500 list for the most energy-efficient supercomputer. Lenovo’s commitment to energy efficiency is further demonstrated by the inclusion of another system, South Korea’s Institute for Basic Sciences system, in the Green500’s top ten.

Lenovo’s achievements in supercomputing, its commitment to technological leadership, and its dedication to advancing scientific research make it a key player in driving HPC innovation and solving global challenges. With MareNostrum 5 and its technologies, Lenovo is poised to shape the future of supercomputing and enable scientific discoveries.

Technology Explained


Liquid Cooling: Liquid cooling is a technology used to cool down computer components, such as processors, graphics cards, and other components that generate a lot of heat. It works by circulating a liquid coolant, such as water or a special coolant, through a series of pipes and radiators. The liquid absorbs the heat from the components and then dissipates it into the air. This technology is becoming increasingly popular in the computer industry due to its ability to provide more efficient cooling than traditional air cooling methods. Liquid cooling can also be used to overclock components, allowing them to run at higher speeds than their rated speeds. This technology is becoming increasingly popular in the gaming industry, as it allows gamers to get the most out of their hardware.


Xeon: The Intel Xeon processor is a powerful and reliable processor used in many computer systems. It is a multi-core processor that is designed to handle multiple tasks simultaneously. It is used in servers, workstations, and high-end desktop computers. It is also used in many embedded systems, such as routers and switches.
