UK launches its most powerful supercomputer in Bristol

The UK’s most powerful AI supercomputer was launched in Bristol. The new Isambard-AI facility is developed by the University of Bristol in close partnership with HPE and NVIDIA, and is able to process in one second what it would take the entire global population 80 years to achieve. This will allow researchers and industry to harness the huge potential of AI in fields such as robotics, big data, climate research and drug discovery.

The supercomputer is a key part of the UK Government’s AI Research Resource (AIRR), intended to boost the country’s capabilities in responsible and cutting-edge AI development.

Named after revolutionary engineer Isambard Kingdom Brunel – a nod to the region’s historic contributions to engineering and innovation – Isambard-AI was built in partnership with HPE, using next-generation supercomputing with HPE Cray EX that is optimized for AI workloads with 5,400 cutting-edge NVIDIA GH200 Grace Hopper Superchips.

It is not only the 6th fastest supercomputer in Europe, it is also the 4th greenest in the world according to the Green500 list. Built to be incredibly energy efficient, the facility exclusively uses zero carbon electricity. It has been built in a low-carbon, modular data centre, installed by Oakland Construction, leading to a reduction in carbon emissions of around 72% compared to traditional build methods.

The supercomputer also utilizes HPE’s 100% fan-less, direct liquid cooling technology to deliver up to 90% reduction in cooling power consumption. There is also potential to recycle the waste heat output for nearby homes and businesses.
