The LUMI Supercomputer
At the time of installation in late 2021, the LUMI supercomputer will be one of the world's fastest computer systems, with theoretical power of more than 550 petaflops. This means 550 quintillion calculations per second. LUMI’s performance will be sevenfold compared to one of Europe’s fastest supercomputers today (Juwels in Germany). LUMI will also be one of the world’s leading platforms for artificial intelligence.
LUMI is a GPU-accelerated supercomputer enabling the convergence of high-performance computing, artificial intelligence, and high-performance data analytics.
The largest partition of the system is the LUMI-G consisting of GPU accelerated nodes using future-generation AMD instinct GPUs. A smaller CPU-only partition, LUMI-C features third-generation AMD Epyc CPUs.
LUMI will become available as a resource in the same way as the other Sigma2 resources, with the same application and evaluation process.
LUMI is aimed at AI and HPC workloads that can take advantage of GPU accelerators. LUMI-G is based on AMD GPU Accelerators and AI researchers using one of the larger frameworks, such as TensorFlow and PyTorch, will be able to use LUMI-G directly.
LUMI-C is the compute partition of LUMI, dealing with CPU based HPC applications. Users interested in this partition should also consider the other clusters already in operation in Norway.
As part of EuroHPC, LUMI is also available for industry usage. The conditions for this type of usage and procedure for applications are still being worked out. Please contact the Norwegian Competence Centre for more information.
If you wish to use LUMI, you apply for access through the regular Sigma2 call for resources prior to each period start (1 April and 1 October). We manage LUMI as an extension to the national e-infrastructure resources.
Please contact us at email@example.com if you want to know more about LUMI and how to get access.
Deploying world-class exascale-level supercomputing infrastructure in Europe. This is the main goal of the EuroHPC Joint Undertaking - a joint initiative between the European Union, European countries, and private partners. Half of the LUMI resources belong to the EuroHPC Joint Undertaking, and the other half of the resources belong to the participating countries, currently estimated to be 2% for Norway. Each consortium country has a share of the resources based on the country’s contribution to the LUMI funding, and the countries will allocate these resources according to local considerations and policies.
The LUMI consortium consists of the following countries: Belgium, Czech Republic, Denmark, Estonia, Finland, Iceland, Norway, Poland, Sweden, and Switzerland.
The EuroHPC JU is behind 8 new pan-European supercomputers – 3 pre-exascale (among them LUMI) and 5 exascale, some still under deployment and some currently operational.
LUMI is installed at CSC's datacentre in Kajaani, Finland and hosted by the LUMI consortium. It is powered 100% by hydroelectricity, and its waste heat will cover 20% of the Kajaani's annual district heating needs.
