The TOP500 list of the world's most powerful supercomputers is announced twice a year at international supercomputing conferences. It also includes the announcement of the Green500 list, which evaluates supercomputers in terms of their energy efficiency. The energy efficiency of the most powerful Czech supercomputer, Karolina, which is located at IT4Innovations National Supercomputing Center of VSB - Technical University of Ostrava, brought already great ranking in the Green500 List in June. At that time Karolina was ranked 8th in Europe. Since then, further dynamic tuning of Karolina's parameters has been carried out, such as tuning of processor frequencies when running parallel supercomputing applications. All of this has now earned Karolina in St. Louis, USA, the 8th place worldwide and the 3rd place in Europe in the Green500 list.
"I am extremely pleased with Karolina's position. Since June, we have taken a number of targeted steps to improve Karolina's energy efficiency, which has been reflected in the Green500 list. We now closely monitor energy consumption for everything - whether it is household appliances or machinery and equipment in manufacturing plants. This is also the case with supercomputers, the energy consumption of which reaches very high numbers in relation to their power, and it is therefore our priority to continuously improve energy efficiency," said Vít Vondrák, Managing Director of IT4Innovations National Supercomputing Center.
"The next generation of supercomputers will need to use energy-efficient solutions and contribute to environmental goals while delivering world-class supercomputing capabilities," said Anders Jensen, CEO of the pan-European EuroHPC Joint Undertaking involved in the acquisition of Karolina, adding: "In addition, Karolina and all EuroHPC supercomputers will be accessible to European researchers, SMEs, and organisations working on key environmental and climate issues in the coming years. Green and sustainable technologies are a priority for us as part of the European Green Deal's goal of a climate-neutral Europe by 2050."
