The UK government has announced a groundbreaking $273 million investment to develop Isambard-AI, its most powerful supercomputer to date. When operational, Isambard-AI will rank among the top AI supercomputers globally. Utilizing thousands of NVIDIA superchips, it will be capable of performing over 200 quadrillion calculations per second.
Expected to begin operations in the summer of 2024, Isambard-AI will be hosted by the University of Bristol. The supercomputer, built by Hewlett Packard Enterprise, will incorporate 5,448 of NVIDIA’s GH200 Grace Hopper Superchips, achieving over 21 exaflops of AI performance—equivalent to over 21 quintillion floating point operations per second. This immense processing power will significantly enhance AI applications, including the training of large language models.
The University of Bristol reports that Isambard-AI will be ten times faster than the fastest supercomputer currently in the UK. It will be housed in a self-cooled, self-contained data center at Bristol’s National Composites Center.
This announcement coincided with the UK's AI Safety Summit, where global leaders, including those from the US, are discussing the future and risks of AI. Ultimately, Isambard-AI is set to connect with other supercomputers in the UK, further enhancing computational capabilities. According to Simon McIntosh-Smith from the University of Bristol, Isambard-AI “will be one of the most powerful AI systems for open science anywhere.”
