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 would place it among the top five most powerful computers in the world.
Architecture
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][4] 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.[5] 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 file system, 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.[6]
Funding
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.[7]
Energy
The computer will use 100% hydroelectric energy, and the heat it generates will be captured and used to heat buildings in the area,[8][9] making LUMI one of the most environmentally efficient supercomputers in the world.[10] Using hydroelectricity will also guarantee reliability of the power supply, estimated to cause a single 2 minute outage on average every 38 years.[11]
Operation
Half of LUMI's capacity belongs to the EuroHPC Joint Undertaking, 20% of which is reserved for industry and SME use.[12] The other half is shared among the LUMI Consortium countries, according to each country’s financial contribution.[13]
By June 2021 pilot projects had been selected for the first run of the CPU partition, scheduled for September 2021, with full operations including the GPU partition planned for early 2022.[14]
Naming
The word "lumi" means "snow" in Finnish.[15]
