The realisation of DG's volumetric kernels has got its fair attention. We focus on techniques to reduce the coupling between cells and increase the cell level parallelism.

Tobias Weinzierl @tobiasweinzierl.bsky.social · 6d

All the implementations were championed through an RSR at Durham's ARC and the project kicked off as part of an #ExCALIBUR project.

Paper alert: arxiv.org/abs/2510.00998 Together with our friends in Bath, we discuss some techniques how to implement DG on modern computers where we need high concurrency and as few memory accesses as possible.

Implementation techniques for multigrid solvers for high-order Discontinuous Galerkin methods

Matrix-free geometric multigrid solvers for elliptic PDEs that have been discretised with Higher-order Discontinuous Galerkin (DG) methods are ideally suited to exploit state-of-the-art computer archi...

Great talk from Marion Weinzierl (Let's stop pretending to be unicorns!) about better management of expectations of RSEs

In case you wondered where the RSE unicorn came from there is the quote from Cristin who designed the logo.
