Description:
Britain's fastest supercomputer is powered by nearly 5,500 GH200 chips.

FULL STORY
======================================================================Nvidia's
 GH200 chips are at the core of Britain's Isambard-AI supercomputer It's the 
11th fastest in the world, and 10x faster than Britain's second-fastest The 
UK government hopes it'll aid in drug discovery and more 

The UK's most powerful AI supercomputer, Isambard-AI, is now fully 
operational at the Bristol Centre for Supercomputing (BriCS), with some 
serious Nvidia power at its core. 

With 21 exaFlops of AI performance backed by 5,448 Nvidia GH200 Grace Hopper 
superchips, Isambard-AI now ranks 11th on the Top 500 list of fastest 
supercomputers, making it one of the global leaders. 

Nvidia declared the British supercomputer is now 10x faster than the next UK 
supercomputer, and more powerful than all the others in the UK combined. A 
giant leap forward 

Besides being the 11th fastest supercomputer globally, Isambard-AI also ranks 
fourth globally on the Green500 list for energy efficiency, demonstrating the 
progress being made to reduce the environmental impact of AI machines and 
data centers. 

Its eco-credentials are endless, including carbon-free power, waste heat 
recycling and a power usage effectiveness (PUE) of below 1.1  among the best 
in the world. 

Build in collaboration with Nvidia, HPE and the University of Bristol, 
Isambard-AI received 225 million in government funding in the hope that the 
supercomputer would go on to aid across important humanitarian issues like 
drug discovery and climate modeling. 

"And as we press this switch to activate the UKs most powerful supercomputer, 
we are embarking on Britains super future where AI contributes towards the 
delivery of better public services, greater public prosperity, deeper 
scientific discovery and stronger national security," UK Secretary of State 
Peter Kyle commented. 

Among its first projects are Nightingale AI, trained on NHS data to support 
earlier diagnoses and personalized care, BritLLM, designed to promote 
inclusivity and better public service delivery in the UK's languages, 
including Welsh; and UCL Cancer Screening AI for prostate cancer detection.
