LUMI is the fastest supercomputer in Europe and the third fastest globally (the Top500 list published in November 2022). LUMI is also the seventh greenest supercomputer on the planet (the Green500 list published in November 2022).
LUMI, an HPE Cray EX system, has a sustained computing power of 375 petaflops (HPL, High-Performance Linpack) in its final configuration. LUMI is also one of the world’s leading platforms for artificial intelligence.
|LUMI’s sustained computing power (HPL) is 375 petaflops (sustained performance) in its final configuration.|
|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 has an astounding storage of 118 petabytes and an impressive aggregated I/O bandwidth of 2 terabytes per second.|
|LUMI is using 100% hydro-powered energy. Up to 200MWs are available. The waste heat of LUMI produces accounts for about 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.
