The Exascale Computing ALgorithms & Infrastructures Benefiting UK Research (ExCALIBUR) programme ran between October 2019 and March 2025 under the Strategic Priorities Fund.

The £47.5m programme aimed to deliver the next generation of high-performance simulation software for the highest-priority fields in UK research. It involved redesigning high priority computer codes and algorithms to meet the demands of both advancing technology and UK research. 

We led ExCALIBUR with the Engineering and Physical Sciences Research Council (EPSRC). It was also supported by the Public Sector Research Establishment, the UK Atomic Energy Authority (UKAEA) and UK Research and Innovation (UKRI) research councils, including the Natural Environment Research Council (NERC), the Medical Research Council (MRC) and the Science and Technologies Facilities Council (STFC).
