Leonardo is the second of the EuroHPC Joint Undertaking's pre-exascale supercomputers to enter into service following the LUMI system in Finland back in June.The move means that Europe now has two of the four most powerful supercomputers as ranked in the Top500 list, behind the US Frontier exascale system and Japan's Arm-based Fugaku system.- HPC's lost histories will power the future of tech- Nvidia H100-based Henri supercomputer tests AMD's claim on Green500- Azure-based 'AI supercomputer' to use Nvidia GPUs and software- Cerebras's supercomputer has more cores than world's fastest iron – with a big catchThis is set to be joined next year by another pre-exascale supercomputer, the MareNostrum 5 at the Barcelona Supercomputing Center in Spain.These are stepping stones towards the first European exascale supercomputer, Jupiter, which will be based at the Jülich Supercomputing Centre (JSC) in Germany and is expected to arrive sometime in 2023/2024, according to EuroHPC.However, the senior European Commission official speaking to the media said that the tender for Jupiter has yet to be awarded, but the system is expected to be capable of "1,000-plus petaflops" – exascale – when fully operational."
