The UK government has recommitted to building a £750 million ($1bn) supercomputer at the University of Edinburgh despite having initially canceled the project last year.

Plans for the supercomputer were announced as part of Chancellor Rachel Reeves’ spending review, which set out the government’s investment plans for the coming years.

It will support UK R&D efforts in areas such as drug discovery, climate change modeling, and national security, Whitehall officials said.

Details of the supercomputer’s processing power have yet to be revealed, but a government statement said it would “vastly exceed” the capacity of the UK’s current national supercomputer, ARCHER2, which is also based at the university.

Edinburgh was selected to host what at the time was dubbed “the UK’s first exascale supercomputer” in 2023, with £800 million set aside to build a system 50 times more powerful than ARCHER2.

But the plan, formulated under the previous Conservative government, was canceled last year when Labour took office, with the new government claiming the plans were unfunded.

The University of Edinburgh subsequently started lobbying government to have the project restored, and it seems its efforts have paid off. The Scottish university has already spent £31 million ($42m) on a new building to house the supercomputer, and hopes to have the new machine up and running by 2027.

Professor Sir Peter Mathieson, principal and vice-chancellor of the University of Edinburgh, said: “This significant investment will have a profoundly positive impact on the UK’s global standing, and we welcome the vast opportunities it will create for research and innovation.

“Building on the University of Edinburgh’s expertise and experience over decades, this powerful supercomputer will drive economic growth by supporting advancements in medicine, bolstering emerging industries and public services, and unlocking the full potential of AI.

“We look forward to working alongside the UK government and other partners to deliver this critical national resource.”

More details about the system will be revealed in a new UK compute map, set to be published later in the summer.

It will form part of the UK’s AI Research Resource, alongside the Isambard-AI supercomputer at the University of Bristol, and the University of Cambridge’s Dawn system.
