Do You Even PetaFLOP?
The UK Government just inked a £79m with Cray for the Archer2, a 28PFLOPS EPYC powered supercomputer which will be made available to scientists and engineers across the UK. It will contain 5,848 compute nodes, each packing a pair of 64-core AMD Epyc Rome processors clocked at 2.2GHz and a mere 1.57PBs of system memory. If you are pondering how to set one of these up, you need to shop around for something similar to the 23 liquid-cooled Shasta Mountain cabinets that will be used to house this beast.
All three are dwarfed by the world's fastest-known beasts, such as America's 201-petaFLOPS IBM-Nvidia Summit, and the upcoming generation of publicly known exascale monsters.
