LUMI supercomputer

LUMI is EuroHPC JU’s flagship supercomputer and the 8th fastest globally (the Top500 list published in November 2024). LUMI is also the 25th greenest supercomputer on the planet (the Green500 list published in November 2024). You can read more about LUMI’s sustainability on the Sustainable future section.

LUMI, an HPE Cray EX system, has a sustained computing power of 380 petaflops (HPL, High-Performance Linpack) in its final configuration. LUMI is also one of the world’s leading platforms for artificial intelligence.

LUMI facts:

		LUMI’s sustained computing power (HPL) is 380 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 a 23-kilometer-high tower.
		LUMI is using 100% hydro-powered energy. LUMI’s waste heat is used to heat hundreds of households in the city of Kajaani.

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.
