CSC's Mahti ranked 55th on the latest supercomputer Top500 list

CSC's Mahti supercomputer fell by a few places on the newest biannual supercomputer Top500 list. Mahti is ranked 55th on the November 2020 list with a maximum performance of 5.39 Petaflops. Mahti's first appearance in the Top500 list was in June 2020 and Mahti was opened into researchers’ use on 26.08.2020. 
 

Puhti is number 317 with performance of 1.7 Petaflops. The maximum performance is measured by the Linpack Benchmark and Puhti's figure includes all CPU nodes but not GPU nodes. 

The world's most powerful supercomputer is still Fugaku in Japan,  442 Petaflops, and Europe's number one, JUWELS Booster Module (FZJ, Jülich, Germany), is 7th on the list. 

Supercomputer LUMI, which will start operating at CSC's Kajaani data center next year, is predicted to have more than 375 Petaflops of Linpack performance. LUMI is expected to be one of the most powerful supercomputers in the world in its first Top500 listing in November 2021. 

LUMI (Large Unified Modern Infrastructure) is a unique joint European supercomputer project involving ten European countries and the EuroHPC Joint Undertaking.
