Developed in partnership with Intel, Dell Technologies, and key UK research organizations, Dawn is already powering impactful projects—from forecasting Arctic sea ice to enhancing kidney cancer detection. By leveraging high-performance computing, Dawn is helping scientists tackle complex global problems with remarkable speed and precision.
A New Chapter in UK Supercomputing
Dawn marks a significant leap in computational power for the UK. The system was developed through a collaborative effort between the University of Cambridge, UK Research & Innovation, the UK Atomic Energy Authority, Intel, and Dell Technologies. At its core are more than 1000 high-performance Intel GPUs, purpose-built to handle demanding AI training and simulation workloads.
This investment signals a strategic push to equip UK researchers with the advanced tools needed to address urgent global issues. Dawn’s architecture is fine-tuned for projects that demand rapid data processing and large-scale simulations—making it a critical asset in scientific exploration and innovation.
IceNet: Forecasting Arctic Sea Ice with AI
Among Dawn’s flagship projects is IceNet, a cutting-edge AI model developed by the British Antarctic Survey and the Alan Turing Institute. IceNet predicts daily sea ice concentrations up to three months in advance—far beyond what traditional physics-based models can achieve.
The system learns from both historical satellite data and future climate projections, offering improved accuracy in forecasting extreme ice loss events. This matters not only for understanding climate dynamics but also for protecting wildlife habitats and supporting safer, more efficient shipping routes in polar regions.
Thanks to Dawn’s computing power, researchers can continuously retrain IceNet with fresh data, keeping forecasts aligned with fast-changing environmental conditions.
Early Detection of Kidney Cancer
Dawn is also making waves in healthcare. A project led by Cambridge Ph.D. student Bill McGough uses AI to detect kidney cancer by analyzing CT scans with the accuracy of a radiologist—at a fraction of the time and cost.
Kidney cancer often goes undetected until late stages, contributing to around 5000 deaths annually in the UK. This AI tool, trained on thousands of multi-phase CT scans, identifies cancer-related patterns even in lower-dose imaging, improving both safety and accessibility.
With Dawn’s ability to process massive datasets, large-scale screening becomes a real possibility. If adopted by the NHS, this approach could allow millions to be screened each year, catching cancer earlier and easing the healthcare burden.
Supporting the Future of Fusion Energy
Beyond health and climate, Dawn is playing a crucial role in advancing clean energy. The UK Atomic Energy Authority is using it to simulate next-generation fusion reactors, including the STEP (Spherical Tokamak for Energy Production) program.
Fusion energy—the same process that powers the sun—offers a nearly limitless, low-carbon energy source. But bringing it to Earth requires solving massive engineering challenges. With Dawn, researchers can develop digital twins of reactors and run complex simulations to test designs and troubleshoot issues like plasma turbulence and magnetic confinement.
This simulation-led approach reduces the need for expensive physical prototypes, helping accelerate progress toward the UK’s target of a commercial fusion reactor in the 2040s.
Final Thoughts
Dawn highlights the real-world value of next-generation supercomputing. Whether it's improving climate resilience, advancing early cancer detection, or accelerating the path to sustainable energy, Dawn is helping researchers turn ambitious ideas into actionable solutions.
Its success also underscores the power of collaboration between academia, government, and industry in tackling today’s biggest scientific and societal challenges.
