ExaGRyPE

ExaGRyPE is a suite of numerical relativity applications built with ExaHyPE which in turn sits on top of Peano. Therefore, its documentation is hosted as part of the whole Peano PDE framework. Peano’s landing page can be found at www.peano-framework.org.

    Paper alert: thanks to funding through the #eCSE programme we have completed a first version of our domain specific language DSLHyPE for ExaHyPE to model compute kernels for hyperbolic PDEs for CPUs and GPUs. This is joint work with friends from @epcc.bsky.social : arxiv.org/abs/2608.19273 https://arxiv.org/abs/2608.19273

    I think I wrote about this before, but a lot interesting recordings from the Durham #HPCDays2026 are now available at www.youtube.com/@Durham_HPC. Besides that, you find a lot of our C++ training there as a latest update! https://www.youtube.com/@Durham_HPC

    I travelled to WCCM in Munich today and the first talk I attended was on the impact of climate change on historic masonry. It presented studies from Durham Castle. The world is small ...

    This is an interesting paper to read: arxiv.org/pdf/2607.04881 It addresses a fundamental issue we have in many octree-based codes: The number of leaves explodes as we go down the hierarchy even though we might not need isotropic refinement. https://arxiv.org/pdf/2607.04881

    There's a great article on the @cake-dri.bsky.social webpage (it is not written by us!) summarising some impressions from the #HPCDays in Durham this year. What a great show, what a great community. https://www.cake.ac.uk/news/k8s-cake-at-dhpcd/
