LUMI retains its position on Top500

The new Top500 list of the fastest supercomputers was released at the SC25 conference in St. Louis, Missouri, USA. LUMI, EuroHPC Joint Undertaking’s top-tier supercomputer operated by the LUMI consortium, retained its 9th position on the Top500 list reaching a measured High-Performance Linpack (HPL) performance of 379.7 petaflops. Since its launch, LUMI has provided leading-edge high-performance computing (HPC) and AI capacity for around 3500 research projects in academia and industry. Over half of LUMI’s computing resources have been utilized for AI-related research and innovation.

In addition to the Top500 list, several other new benchmark lists were published at SC25.

On the new HPCG list (High-Performance Conjugate Gradient) LUMI was ranked number 5, achieving  4.587 pflop/s, like on the last list. The HPCG benchmark provides an alternative metric for assessing supercomputer performance from the memory-bandwidth bound applications point of view and is meant to complement the HPL measurement.

LUMI supercomputer reached the 38th spot on the new Green500 list which biannually ranks supercomputers from the Top500 list in terms of energy efficiency. The GFlops/Watts ratio for LUMI is 53.4. LUMI is one of the greenest supercomputers in the world.

The LUMI supercomputer is supplied by Hewlett Packard Enterprise (HPE), based on an HPE Cray EX supercomputer. The supercomputer is owned by the EuroHPC Joint Undertaking and hosted by the LUMI consortium, including eleven European countries.

LUMI to be succeeded by an AI-optimized supercomputer

To meet the needs of the AI era, the LUMI system will be followed by a new AI-focused supercomputer called LUMI-AI. This system will leverage a large, accelerated partition utilising next-generation GPUs. This supercomputer is part of the LUMI AI Factory, one of the European Union’s AI Factories. The LUMI AI Factory has started its operations utilizing the computing power of the LUMI supercomputer.

The LUMI-AI computing environment will be complemented by an experimental quantum computing platform named LUMI-IQ, designed for workloads combining quantum computing and artificial intelligence. This one-of-a-kind platform will open completely new horizons for research. LUMI-AI and LUMI-IQ will form the most advanced public quantum-accelerated HPC+AI research infrastructure in the world.

Sustainable computing

Like the current LUMI system, the upcoming LUMI-AI system will be fully powered by carbon-free renewable energy, and its waste heat will be utilized in the district heating system of the city of Kajaani, Finland, making the installation one of the most energy-efficient and eco-efficient large AI supercomputers in the world. One of the purposes of the data center is among others to provide a better understanding of climate change and tools for fighting it. This is referred to as a positive handprint, which relates to the benefits of green research and innovation on climate and the environment.
