UK Government Invests £225m to Create UK’s Most Powerful AI Supercomputer With University of Bristol and Hewlett Packard Enterprise

  • University of Bristol awarded £225m of a £300m overall Government investment to make the UK a world leader in AI with new Isambard-AI supercomputer
  • Hewlett Packard Enterprise (HPE) has been named as the supplier to deliver next-generation supercomputing technologies and is due to deliver Isambard-AI at the National Composites Centre in Bristol next summer
  • The new system will be UK’s most powerful supercomputer, with over 5,000 state-of-the-art NVIDIA GH200 superchips, capable of an incredible 200 quadrillion calculations per second
  • Isambard-AI will offer computing capacity never seen before in the UK for researchers and industry to make AI-driven breakthroughs in fields such as robotics, big data, climate research, and drug discovery

As part of the UK Government’s investment in a national AI Research Resource, The University of Bristol and Hewlett Packard Enterprise (NYSE: HPE) today announced that HPE has been selected to deliver the UK’s fastest supercomputer thanks to £225m of Government funding.

The funding injection, part of a £300m package to create a new national Artificial Intelligence Research Resource (AIRR) for the country announced at the government’s AI Safety Summit at Bletchley Park, will make the UK a world leader in AI.

To be known as Isambard-AI, it will be 10 times more powerful than the UK’s current fastest supercomputer and among the most powerful in the world when it opens at the National Composites Centre (NCC) in the summer of 2024.

Isambard-AI will be designed with cutting-edge technologies to drive AI-driven research

Hewlett Packard Enterprise (HPE) will build and deliver the new system with the next generation HPE Cray EX supercomputers and over 5,000 state-of-the-art NVIDIA GH200 superchips. The advanced technologies and design will allow Isambard-AI to reach up to 200 quadrillion calculations per second.

The new Bristol facility will be used by a wide range of organisations from across the UK to harness the power of AI, which is already the main driver of emerging technologies such as training large language models (LLMs), big data and robotics. The new supercomputing facility will also play a vital role in important areas such as accelerating automated drug discovery and climate research.

Isambard-AI will connect with a new supercomputer cluster at the University of Cambridge, called Dawn, which is being developed to offer additional capacity as part of the new national AIRR.

Professor Simon McIntosh-Smith, Director of the Isambard National Research Facility at the University of Bristol, said: “Isambard-AI represents a huge leap forward for AI computational power in the UK. Today Isambard-AI would rank within the top 10 fastest supercomputers in the world and, when in operation later in 2024, it will be one of the most powerful AI systems for open science anywhere.

“It’s immensely exciting to be at the forefront of the AI revolution and to partner with industry leaders HPE and NVIDIA to rapidly build and deploy large-scale research computing infrastructure to create one of the most powerful supercomputers in the world. Isambard-AI will offer capacity never seen before in the UK for researchers and industry to harness the huge potential of AI in fields such as robotics, big data, climate research and drug discovery.”

Justin Hotard, executive vice president and general manager, HPC, AI & Labs at HPE said: "Today's announcement of the UK’s major investment in AI supercomputing underscores its commitment to taking a global leadership position in AI. The Isambard-AI system will harness world-leading supercomputing, including high-performance networking co-developed at HPE's Bristol labs, to provide the performance and scale required for compute-intensive AI projects. We are proud to partner with the UK Government and the University of Bristol to give UK researchers and industry access to Europe's largest AI system for open science."

Ian Buck, vice president of hyperscale and HPC at NVIDIA, said: “In building one of the world's fastest AI supercomputers, the UK is demonstrating the importance for nations to create their own infrastructure. Isambard-AI will provide researchers with the same state-of-the-art AI and HPC compute resources used by the world's leading AI pioneers, enabling the UK to introduce the next wave of AI and scientific breakthroughs.”

The Government’s new Frontier AI Taskforce will have priority access to support its work to mitigate the risks posed by the most advanced forms of AI, including national security from the development of bioweapons and cyberattacks. The resource will also support the work of the AI Safety Institute, as it develops a programme of research looking at the safety of frontier AI models and supports government policy with this analysis.

Michelle Donelan, Secretary of State for Science, Innovation and Technology said: “Frontier AI models are becoming exponentially more powerful. At our AI Safety Summit in Bletchley Park, we have made it clear that Britain is grasping the opportunity to lead the world in adopting this technology safely so we can put it to work and lead healthier, easier and longer lives.

“This means giving Britain’s leading researchers and scientific talent access to the tools they need to delve into how this complicated technology works. That is why we are investing in building UK’s supercomputers, making sure we cement our place as a world-leader in AI safety.”

Notes to editors

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 (i.e. 1.3 billion billion).

Isambard-AI will also feature sophisticated direct liquid-cooling capabilities as part of the HPE Cray EX supercomputer design to improve energy efficiency and overall carbon footprint impact. The system will be hosted in a self-cooled, self-contained data center, using the HPE Performance Optimized Data Center (POD), and will be situated at the National Composites Centre (NCC), based at the Bristol and Bath Science Park. NCC is one of seven research centres across the UK that form the High Value Manufacturing Catapult, helping to turn great ideas into reality by providing access to world-class research and development facilities and expertise that would otherwise be out of reach for many businesses in the UK.

HPE is also collaborating with the University of Bristol on a highly-energy efficient heat re-use model, extracting waste heat from the Isambard-AI system to use as renewable energy to heat local buildings, supporting the Net Zero carbon efficiency targets for 2030/2040 as mandated by the UK Government.

Bristol is one of the top UK universities for AI research and scientific computing. It already plays host to cutting-edge computing technology, including the previously announced Isambard 3 supercomputer, while being home to the UKRI Centre for Doctoral Training in Interactive Artificial Intelligence and the newly announced UKRI AI Centre for Doctoral Training in Practice-Oriented Artificial Intelligence.
