Rapid Access applications will be subject to a light touch review by a member of the UK Research and Innovation (UKRI) and Department for Science, Innovation and Technology (DSIT) delivery team. The aim is that this will be done on a weekly cadence, with a maximum time-to-resource-access of two weeks after the date of submission. The UKRI and DSIT delivery team will use the following assessment criteria: are the project objectives in scope for the AIRR programme? has the project demonstrated that access to AIRR would add value to the project? have any concerns been raised regarding the project compliance information? We reserve the right to modify the assessment process as needed. Contact us at  to ask for guidance. Background The AIRR programme intends to address the significant shortage of publicly available computing resources in the UK. In January 2025 the government announced expanding AIRR capacity by at least 20 times by 2030, as part of the . The government has committed to spending an extra £1 billion to scale up our compute power by a factor of 20, giving Britain the power to become an AI leader. AIRR is a partnership between: UK government UK Research and Innovation (UKRI) University of Cambridge University of Bristol Hewlett Packard Enterprise (HPE) Nvidia Intel Dell AIRR compute clusters The government is investing significantly in the Isambard-AI and Dawn AIRR clusters and will have invested over £350 million by 2030. Isambard-AI (University of Bristol) The Isambard-AI facility is the UK’s most powerful public compute facility. It is made up of 5,448 Nvidia GH200 Grace-Hopper superchips (supplied by HPE) and operated by the University of Bristol at Bristol’s National Composites Centre. . Dawn (University of Cambridge) The Cambridge Dawn facility is made up of 1,024 Intel Data Centre GPU Max 1550 GPUs. It is a close partnership between Cambridge, Intel and Dell at the Cambridge Open Zettascale Lab. . Supporting documents Guidance on how to apply to the Rapid Access route:
