Exascale Computing ALgorithms & Infrastructures Benefiting UK Research (ExCALIBUR)

ExCALIBUR is a UK research programme that aims to deliver the next generation of high-performance simulation software for the highest-priority fields in UK research. It started in October 2019 and will run through until March 2025, redesigning high priority computer codes and algorithms to meet the demands of both advancing technology and UK research. 

ExCALIBUR will achieve this by building on the four pillars: 

Separation of Concerns
The algorithms that encapsulate the mathematics and physics of the problem are separated from the computational science of their implementation.

Holistic design of the software of the entire simulation system involving innovative collaborations between mathematicians, domain scientists and computational scientists.

Data Science
Research to design new workflows adapted to managing & analysing vast volumes of data ingested and produced by simulations.

Investment in People
Improved RSE career development driven by professional forward-looking approach to scientific software design of simulation codes.


The programme is led by the Met Office and the Engineering and Physical Sciences Research Council (EPSRC) along with 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).
