Interview: Sunrise, a supercomputer for nuclear fusion research | Computer Weekly
"One area in which Sunrise will be used is accelerating simulation, surrogates and design, where AI could simplify simulations or learn the behaviour of complex systems such as plasmas to speed up simulations that previously took weeks or months to run."
"The role of high-performance computing (HPC) AI acceleration hardware within the government's strategy for nuclear fusion is to prepare fusion data for AI applications to ensure that researchers from small and medium-sized enterprises (SMEs) and academic institutions can access data, supporting greater collaboration and engagement with industry partners."
"It will also be used for data management, making the UK Atomic Energy Authority's (UKAEA) fusion research and experimental data consistent, accessible and electronically readable. In addition, Sunrise offers the UKAEA the ability to enhance experimental operations and control in real-time diagnostics, where AI can be trained to spot anomalies and flag issues."
The UK fusion strategy 2026 allocates £125m funding for an AI growth zone at Culham, Oxfordshire, with £45m dedicated to Sunrise, a 6.76 exaflops supercomputer. Sunrise accelerates fusion research through multiple applications: it simplifies complex plasma simulations that previously required weeks or months, manages and standardizes fusion research data for accessibility, and enables real-time diagnostics where AI detects anomalies. The supercomputer supports collaboration between the UKAEA, academic institutions, and SMEs by preparing fusion data for AI applications. Sunrise represents a collaborative effort involving AMD, Dell Technologies, Intel, the University of Cambridge, and other partners, offering flexible floating-point precision from 8-bit to 64-bit to meet diverse computational needs.
