Extract from Press Release
LUMI is a unique European supercomputer endeavour, Norway including nine partner European countries and the EuroHPC Joint Undertaking (EuroHPC JU) investing in one joint system. It is set to boost research, employment and competitiveness throughout Europe. The procurement process of LUMI is now complete, and the system supplier is Hewlett Packard Enterprise (HPE), providing an HPE Cray EX supercomputer with next-generation AMD EPYC™ CPUs and AMD Instinct™ GPUs. In addition to the remarkable computing power, LUMI is also one of the world’s most advanced platforms for artificial intelligence (AI) and it will be one of the world’s best known scientific instruments throughout its lifetime.
- "Today we mark an important step forward in the realisation of the European High-Performance Computing strategy. The pre-exascale supercomputer hosted by the LUMI consortium will be among the top 5 in the world. Together with the other EuroHPC pre-exascale and petascale supercomputers that will be deployed in 2021, the LUMI supercomputer will help Europe’s public and private users address many daunting research and innovation problems across different areas from weather and climate change through cybersecurity to drug discovery and personalised medicine. LUMI supercomputer aligns the Digital and Green Deal policies of the European Commission, using 100% renewable carbon-neutral energy. Moreover, the heat generated will provide 20 per cent of the district heat of the area, being one of the most efficient supercomputers in the world", says Khalil Rouhana, Deputy Director-General of the Directorate‑General for Communications Networks, Content and Technology (DG Connect) of the European Commission.
- "Once operational in mid-2021, the LUMI supercomputer will be one of the most competitive and green supercomputers in the world! Such a leadership-class system will support European researchers, industry and public sector, in better understanding and responding to complex challenges and transforming them into innovation opportunities in sectors like health, weather forecasting or urban and rural planning", says EuroHPC Joint Undertaking’s Executive Director Anders Dam Jensen.
- "We are committed to supporting the European High-Performance Computing Joint Undertaking (EuroHPC JU) to seize opportunities in next-generation supercomputing and bolster R&D in science, advance innovation and unlock economic growth. We are honoured to continue collaborating with EuroHPC JU, and through our partnership with AMD, build one of the world’s fastest pre-exascale supercomputers for Europe.”, says Peter Ungaro, senior vice president and general manager, high-performance computing (HPC) and mission-critical solutions (MCS), HPE.
- "The reliability of CSC and Finland made the European Commission and ten partner countries invest in one pan-European high-performance computing and data management infrastructure in Finland. We have to keep up the excellent collaboration to maximize this investment to benefit society on a larger scale", says Permanent Secretary Anita Lehikoinen from the Ministry of Education and Culture, Finland
Investment of 200 million Euros
LUMI is an investment of over 200 million Euros, covering the whole lifecycle of the system. It will lift Europe to the forefront of high-performance computing (HPC) and research. Exploiting the potential of the data economy is a crucial factor for Europe’s competitiveness. The investment will make CSC’s data centre one of the world’s largest players in the field of HPC.
- "The investment will make CSC data centre one of the world’s largest players in the field of HPC. The joint procurement process with the EuroHPC Joint Undertaking and ten European countries has proceeded on schedule despite the global pandemic, thanks to the vast know-how of the LUMI consortium and the excellent collaboration. LUMI's astonishing computing power combined with a very modern artificial intelligence platform and data management infrastructure will help European researchers tackle unforeseen research questions", says CSC's Managing Director Kimmo Koski.
The uptake of HPC will increase the competitiveness of small and medium-sized enterprises (SMEs) in Europe remarkably. Up to one-fifth of LUMI’s resources will be available for industry and SMEs.
Supercomputers fight against pandemics and resolve unforeseen research questions
LUMI's top-notch computing resources are needed in leading-edge research in a wide range of data- and computing-intensive fields. Examples include climate, pharmaceutical, and artificial intelligence.
LUMI will also have a channel for urgent computing for time- and mission-critical simulations. This kind of simulation might be, for example, related to a large epidemic or pandemic disease. The current COVID-19 pandemic has largely benefitted from supercomputers: supercomputers have been used for example to simulate studies related to vaccine research and defeat the spread of the virus. With its vast computing resources, LUMI can answer different research questions even faster than before. It will also enable new types of research questions combining multidisciplinary research and artificial intelligence.
- "It is of the utmost importance for Norwegian researchers to have access to e-infrastructure at a high international level to be competitive, and a continuing growing number of research groups will benefit greatly from the computational power of the new LUMI system", says Gunnar Bøe, Managing Director of UNINETT Sigma2 in Norway. "The convergence of HPC and AI is an exciting new development giving Norwegian researchers opportunities they have not had before".
CSC’s data centre in Kajaani is one of the world’s most eco-efficient data centres: it uses 100% hydropower. LUMI's waste heat will be used in Kajaani's district heating network: 20% of the area's yearly district heating needs will be covered with LUMI's waste heat.
LUMI system architecture explained:
- The LUMI system will be supplied by Hewlett Packard Enterprise (HPE), based on an HPE Cray EX supercomputer.
- The peak performance of LUMI is an astonishing 552 petaflop/s meaning 552 * 1015 floating-point operations per second. This figure makes LUMI one of the world’s fastest supercomputers. For comparison, the world’s fastest computer today (Fugaku in Japan) reaches 513 petaflop/s and the second fastest (Summit in the US) 200 petaflop/s (more information: www.top500.org). If LUMI’s computing power were compared to normal laptops, it would require 1.5 million laptops together to reach the performance of LUMI. If these laptops were piled up, they would form a tower of over 23 kilometres high!
- LUMI will also be one of the most advanced platforms in the world for artificial intelligence (AI). With LUMI, it will be possible to combine AI, especially deep learning, and traditional large scale simulations combined with massive-scale data analytics in solving one research problem.
- The number-crunching capability of LUMI is accelerated by the GPU (Graphics Processing Unit) partition. It is based on the future generation AMD Instinct™ GPU.
- LUMI will be complemented by a CPU (Central Processing Unit) partition, featuring 64-core next-generation AMD EPYC™ CPUs.
- LUMI’s data analytics partition has 32 aggregated terabytes of memory and 64 visualization GPUs. This partition is used e.g. for visualization, heavy data analysis, meshing and pre/post-processing.
- LUMI’s storage system will consist of three components. First, there will be a 7-petabyte partition of ultra-fast flash storage, combined with a more traditional 80-petabyte capacity storage, both based on the Lustre parallel filesystem, as well as a data management service, based on Ceph and being 30 petabytes in volume.
- In total, LUMI will have astounding storage of 117 petabytes and an impressive aggregated I/O bandwidth of 2 terabytes per second
- LUMI will also have an OpenShift/Kubernetes container cloud platform for running microservices.
- All the different compute and storage partitions are connected to the very fast Cray Slingshot interconnect of 200 Gbit/s. The global bandwidth of the LUMI-GPU partition is 160 TB/s. The global Internet traffic would fit therein, in fact, two times!
- LUMI takes over 150m2 of space, which is about the size of a tennis court. The weight of the system is nearly 150 000 kilograms (150 metric tons).
