| Description | The award has allowed the team to develop software for lattice field theory simulations on new architectures. In particular, simulations that are relevant for studies of physics beyond the Standard Model have been ported to GPUs, which enables the team to run code on the latest machines available to our community. |
| Exploitation Route | The code that has been developed is now merged in the codebase Grid and is publicly available. |
| Sectors | Digital/Communication/Information Technologies (including Software) |
| Description | We have continued to develop software for simulations of theories beyond the Standard Model on GPU architectures. The experience we have developed working with software for high-energy physics will be useful for benchmarking and procurement of high-performance computing hardware. |

| Description | Development of Grid software |
| Organisation | Swansea University |
| Country | United Kingdom |
| Sector | Academic/University |
| PI Contribution | In partnership with Swansea University we have extended the Grid software to be able to simulate lattice gauge theories with a symplectic gauge group. Symplectic gauge theories coupled to matter fields lead to symmetry enhancement phenomena that have potential applications in such diverse contexts as composite Higgs, top partial compositeness, strongly interacting dark matter, and dilaton-Higgs models. These theories are also interesting on theoretical grounds, for example in reference to the approach to the large-N limit. The Grid software is one of the leading community codes for simulating lattice field theories, and is extensively used for benchmarking new hardware. An extensive physics programme involving two new PhD students is already under way, which is going to rely on this code development. |
| Collaborator Contribution | Work in close collaboration between Edinburgh (expertise in Grid) and Swansea (expertise in symplectic gauge theories) was necessary for the full deployment of the simulation code in the Grid framework. |
