Construction work has begun at the supercomputer in Midlothian
Written by Midlothian View Reporter, Liam Eunson
Construction work has begun on the UK’s new £750 million supercomputer, being built on the outskirts of Penicuik and Roslin.
With experts hailing it as a milestone moment, the project brings the country a step closer to turbo-charging its capacity for research and innovation.
Started today, the project hosted by the University of Edinburgh is supported by £750 million funding from the UK Government.
The supercomputer, owned by UK Research and Innovation (UKRI), is set to ‘empower world-changing discoveries in globally significant fields such as aircraft engineering, extreme weather events and drug discovery for cancer’.
Supercomputing also allows researchers to model flood risks for communities, understand changes in our ocean temperatures, and simulate earthquakes – challenges that are simply unfeasible or prohibitively costly to do in the real-world.
It marks a step-change in the UK’s compute power, aiming to cement the country’s status as a leader in supercomputing, with experts explaining that the project is ‘critical for driving economic growth’.
The new machine is expected to have thousands of the latest processers, allowing it to deliver at least a billion – billion calculations per second, up from the 20 million – billion calculations per second currently delivered by the current national supercomputer.
At around fifty times more powerful than the UK’s current national supercomputer, ARCHER2, the new system will be able to carry out incredibly complex calculations in hours rather than days, and solve much larger problems than ever before. This will help make today’s impossible calculations possible.
Director of the EPCC and Dean of Research Computing, Professor Mark Parsons, explained:
“You would never guess from this ordinary-looking building site just how vitally important it will be for the UK and how its contents could impact on all of our lives positively. This marks a profound leap in compute power for the UK. The value of this supercomputer across our society is vast, and will aid strong industry, a healthier economy and a happier population.”
Constructed in Midlothian, developers explained that having the supercomputer sited in Scotland has been a benefit to sustainability concerns thanks to its cooler air, with nature offering a simple solution to cool the system, combined with leading-edge cooling technology reducing the energy required.
Environmental considerations are at the forefront of the new supercomputer’s design, which will be more efficient than existing models, with surplus heat generated being used to warm University buildings and research planned to assess if it could also be used to warm local homes, by warming mine-water in disused mines.
Principal and Vice-Chancellor, Professor Peter Mathieson, explained:
“It is an honour for the University to be trusted to host this essential piece of UK infrastructure, and a testament to the hard work of everyone involved to help make this happen. It is clear that this investment will strengthen UK science and with our track record in supercomputing, Edinburgh is perfectly placed to host this.”
It was explained that the University was chosen as the new supercomputer’s home in recognition of EPCC’s leadership in high performance computing for more than 30 years.
The University has been the home of AI research in Europe for six decades, with EPCC recently formally designated the first UK National Supercomputing Centre.
ARCHER2 – also housed at the University – aided Covid-19 drug-discovery, empowered firms like Rolls Royce to improve aircraft engine efficiency and sustainability, and has enabled engineers to make wind farms more efficient.
Supercomputing also allows researchers to model flood risks for communities, understand changes in our ocean temperatures, and simulate earthquakes – challenges that are simply unfeasible or prohibitively costly to do in the real-world.
A recent independent report showed that ARCHER2 generated £8 per £1 invested, enabling more than £4.2bn in benefits for the UK economy.
Vice-Principal for Research and Innovation and Chair of Food and Environmental Security, Professor Liz Baggs, added:
“The best research advances can happen when skills and talent are enabled by exceptional tools. This supercomputer has the potential to help UK researchers accelerate frontiers, unlock new paradigms, and develop solutions to challenges that were previously impossible. This includes creating the next generation of medicines, revealing untold stories about our planet, and, most excitingly, leading to discoveries that we can’t even imagine yet.”
ARCHER2 is already designated as net zero in operation, thanks to its use of 100% green certified electricity. The current supercomputing facility estimates that it runs with the same water usage as three typical bungalows.
Site demolition has been kept to a minimum to reduce environmental impacts and a number of sustainability projects are planned with the construction team, including tree planting, protecting ancient trees, and conservation projects for local wildlife.
Minister for AI and Online Safety, Kanishka Narayan, explained:
“Today’s milestone in Edinburgh marks a decisive step in delivering our Compute Roadmap – building the sovereign computing power Britain needs to stay in control of its future in AI and science. For decades, Edinburgh has been at the heart of world-leading supercomputing. This new machine takes that further – making sure UK researchers, businesses and innovators have the cutting-edge power they need here in the UK, rather than relying on others. This is what will unlock the next generation of breakthroughs – from training more powerful AI systems to accelerating scientific discovery and creating new products and high-growth businesses. It is our Industrial Strategy in action, turning British ideas into the jobs and industries of the future.”
