LUMI (Large Unified Modern Infrastructure) is a petascale ("pre-exascale"[1]) supercomputer currently under construction at the CSC data center[2] in Kajaani, Finland. The completed system will consist of around 200,000 cores, capable of executing more than 375 petaflops, with a theoretical peak performance of more than 550 petaflops, which will place it among the top five most powerful computers in the world. The system is being supplied by Hewlett Packard Enterprise (HPE), providing an HPE Cray EX supercomputer with next generation 64-core AMD EPYC CPUs and AMD Radeon Instinct GPUs[3]. LUMI is a GPU based system, and the majority of its computing power comes from its GPU cores, an architecture which was chosen primarily for its cost/performance advantage[4]. The system will be equipped with 32 terabytes of RAM, and storage will include a 7-petabyte partition of flash storage, combined with 80-petabytes of traditional storage, both based on the Lustre parallel filesystem, as well as a 30-petabyte data management service based on Ceph. This will give the system a total of 117 petabytes of storage with an aggregated I/O bandwidth of 2 terabytes per second[5].
LUMI is co-funded by the EuroHPC Joint Undertaking and the LUMI Consortium, which is composed of the following countries: Finland, Belgium, Czech Republic, Denmark, Estonia, Iceland, Norway, Poland, Sweden, and Switzerland. The total budget is €144.5 million[6].
The computer will use 100% renewable carbon neutral energy, and the heat it generates will be captured and used to heat buildings in the area[7].
"Lumi" means "snow" in Finnish[8].
