First European pre-exascale supercomputers forgo homegrown CPUs

November 20, 2019

It is now pretty much assured that the first three pre-exascale systems being installed in the European Union will not be powered by processors being developed under the European Processor Initiative (EPI).

The three upcoming pre-exascale machines – LUMI at CSC in Finland, Leonardo at CINECA in Italy, and MareNostrum 5 at BSC in Spain – are scheduled to begin installation in 2020 and be operational in late 2020 or in 2021. The first-generation Arm and RISC-V processors from the EPI effort, which were originally aimed at the pre-exascale supercomputers, are scheduled to be available in 2021, which means the timelines no longer match up.
