The European Commission recently released a statement stating that the latest world-class supercomputer in Europe, MareNostrum5, has been built at the Supercomputing Center in Barcelona, Spain and will be open to users in the European scientific and industrial communities starting from March 2024. As one of the 10 most powerful supercomputers in the world, this computer is specifically designed to solve complex scientific problems, with a peak performance of 3.14 billion floating-point operations per second. It will support research in Europe in areas such as drug and vaccine development, simulated virus transmission, climate change, engineering, materials science, and earth science. According to the Spanish newspaper Abesai, this supercomputer uses the most advanced accelerator chip currently available, which will assist in the development of artificial intelligence and improve the performance of large-scale artificial intelligence language models in Europe. Meanwhile, the computer is completely powered by sustainable energy, and the heat generated during operation will be used to heat the building, making it one of the most environmentally friendly supercomputers in Europe. Supercomputers are crucial for scientific research, especially in the field of artificial intelligence, which has broad application prospects. In recent years, the European Union has actively developed supercomputers to promote digital transformation, enhance regional technological level and industrial competitiveness. As early as 2018, the European Commission and member states launched the "European High Performance Computing Common Plan", which coordinates the deployment and operation of world-class high-performance computing and data infrastructure within the EU, and concentrates resources on building the European high-performance computing ecosystem. In 2019, the European Commission selected 8 locations among member states, including Barcelona, to build world-class supercomputing centers, with the aim of making Europe a top supercomputing region in the world. According to the information released by the European High Performance Computing Joint Program, the project is jointly funded by its members and currently plans to invest 7 billion euros between 2021 and 2027. The EU will aggregate resources from all parties and establish high-performance computing and big data systems. The EU will also integrate a batch of quantum computers into supercomputer networks and enhance computing power. At present, at least half of the components of the European supercomputers under construction are based on local European technology. According to the latest Global Supercomputer 500 list released in November last year, three of the top ten supercomputers in the world currently come from the European Union. At present, the European Union is still promoting the establishment of a world-class billion dollar secondary supercomputing center. Last October, the European High Performance Computing Joint Program announced the procurement of a billion dollar secondary supercomputer called Jupiter, which is expected to be put into use by the end of 2024. Users, including European scientists, will be able to access the system for scientific research activities. Another billion dollar secondary supercomputer located in France is also under construction. Andrews Ansip, former Vice President of the European Commission responsible for the construction of the EU's single digital market, stated that these investments are crucial for Europe to acquire the next generation of computing power and will help the EU move towards future technological fields such as the Internet of Things, artificial intelligence, robotics, and data analysis. European Commission President von der Leyen said that these supercomputers will also provide assistance for AI start-ups, shorten development time, and accelerate the prediction of related technologies in extreme weather
