Covering Disruptive Technology Powering Business in The Digital Age

Details of a £225m investment from the Government to create the UK’s fastest supercomputer at the University of Bristol have been announced today [1 November 2023].

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.

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.

Science, Innovation and Technology Secretary Michelle Donelan 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.”

Isambard-AI will be hosted in a self-cooled, self-contained data centre, 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.

Richard Oldfield, Chief Executive Officer, National Composites Centre, said: “We are immensely proud to be hosting Isambard-AI at the National Composites Centre. This underpins our vision of bringing together world-class innovators, academic researchers and cutting-edge technology to solve some of the world’s most complex engineering challenges.

“Building on our expertise and state-of-the-art capability in accelerating industrial transformation from fundamental research to industrial application, we’re excited to be the home of the UK’s national AI supercomputing facility.”

Phase one of the system, available in March 2024, will utilise Isambard 3 – a TOP500-class supercomputer service for AI and high-performance computing (HPC). This is due to be installed at the NCC at the start of 2024 and was developed in collaboration with the GW4 group of universities – an alliance made up of the Universities of Bath, Bristol, Cardiff and Exeter. It will offer early access to UK-based scientists, researchers and developers so their research can get underway as soon as possible.

GW4 Alliance Director, Dr Joanna Jenkinson MBE, said: “Isambard-AI builds on the success of the GW4 Isambard Supercomputer, which started as a GW4 collaborative research community, and was the world’s first Arm-based computer to go into production use. Through GW4 Isambard, we have already seen progress made across research into vital areas such as Parkinson’s disease, osteoporosis and supporting patients with heart failure.

“I am delighted the strength and innovation of GW4 Isambard, and the importance of supporting academic and industrial collaboration, has helped to enable this new national Artificial Intelligence Research Resource – which will supercharge the nation’s digital growth and AI capabilities.”
