LUMI is the fastest supercomputer in Europe and the fifth fastest in the world. It is a pre-exascale system based on AMD technology. It contains 2048 CPU-based compute nodes and 2978 GPU nodes, interconnected with a fast Slingshot-11 network.
LUMI: Europe's fastest supercomputer
Do you want to perform computations on an extreme scale? Meet LUMI, the fastest supercomputer in Europe. LUMI offers all the facilities you need to run your GPU-accelerated or AI applications at an unprecedented scale.
Advantages
Unprecedented scale
LUMI offers a large GPU partition that enables running GPU-accelerated applications on an extreme scale.
Sustainability
LUMI uses 100 percent renewable electricity. Waste heat produced by LUMI is used to heat hundreds of households in the city of Kajaani, Finland, where LUMI is located.
Easy access
Half of LUMI's computational resources belong to the LUMI consortium countries. Access to LUMI for pilot and regular projects can be obtained directly via SURF and NWO.
