Hybridised multigrid preconditioners for a compatible finite‐element dynamical core Open
Compatible finite‐element discretisations for the atmospheric equations of motion have recently attracted considerable interest. Semi‐implicit timestepping methods require the repeated solution of a large saddle‐point system of linear equa…

Scalable and robust Firedrake deployment on ARCHER2 and beyond Open
We summarise the different aspects of Firedrake deployment that we have improved for our HPC users and additional benefits for ARCHER2 users. A Spack package has been created for Firedrake many of its dependencies as well as determining a …

Code Generation for Productive, Portable, and Scalable Finite Element Simulation in Firedrake Open
Creating scalable, high performance PDE-based simulations requires an appropriate combination of models,\ndiscretizations, and solvers. The required combination changes with the application and with the available hardware, yet software\nde…

Multigrid preconditioners for the hybridized Discontinuous Galerkin discretisation of the shallow water equations Open
Numerical climate- and weather-prediction requires the fast solution of the equations of fluid dynamics. Discontinuous Galerkin (DG) discretisations have several advantageous properties. They can be used for arbitrary domains and support a…
