UK Atomic Weapons Establishment readies Shasta supercomputer

The UK Atomic Weapons Establishment (AWE) has selected Cray’s Shasta supercomputer to power the organisation’s nuclear simulations and other science projects supporting UK nuclear deterrence.

The seven petaflop supercomputer is named Vulcan and fitted with AMD’s Epyc 7542 processors, Cray Slingshot interconnect and ClusterStor Lustre storage. 

AWE said Cray’s HPC beast was selected because of its ability to run mixed workloads and applications at a low total cost of ownership (TCO).
