HP And Nvidia Will Supply the UK With a 21 Exaflop AI Supercomputer

Isambard-AI will be built using the HPE Cray EX supercomputer, a next-generation platform architected to support unprecedented performance and scale, and consist of 5,448 NVIDIA GH200 Grace Hopper Superchips which combine NVIDIA’s Arm-based Grace CPU with a Hopper-based GPU optimized for power efficiency and giant-scale AI, along with the latest HPE Slingshot 11 interconnect, and nearly 25 petabytes of storage using the Cray Clusterstor E1000 optimised for AI workflows.

When in production, Isambard-AI will achieve well over 200 PetaFLOP/s using the Top500’s Linpack benchmark, while also achieving over 21 ExaFLOP/s of AI performance to accelerate AI training for large-scale AI, such as large language models.

This represents a massive 10 times improvement over the next fastest system in the UK when Isambard-AI is live, and will enable Isambard-AI to perform over 21 quintillion AI-optimised floating point operations per second.

Details of a £225m investment from the Government to create the UK’s fastest supercomputer at the University of Bristol have been announced today
