LUMI supercomputer

At the time of installation, LUMI will be one of the world’s fastest computer systems, having theoretical computing power of more than 550 petaflops which means 550 quintillion calculations per second. LUMI’s performance will be sevenfold compared to one Europe’s fastest supercomputer today (Juwels, Forschungszentrum Jülich, Germany). LUMI will also be one of the world’s leading platforms for artificial intelligence.

LUMI facts:

LUMI’s computing power will be over 550 petaflops.
LUMI’s computing power is equivalent to the combined performance of 1.5 million of the latest laptop computers. These would form over 23-kilometer high tower.


In total, LUMI will have astounding storage of 117 petabytes and an impressive aggregated I/O bandwidth of 2 terabytes per second.
LUMI is using 100% hydropowered energy. Up to 200MWs are available. The waste heat of LUMI will produce 20 percent of the district heat of the area.


Used technologies: The supercomputer achieves its high performance with a large number of nodes with accelerators (GPUs). In addition, the system is complemented by a CPU only partition, IaaS cloud services, and a large object storage solution.
