Tobias Weinzierl is Professor of High-Performance Computing (HPC) in the Department of Computer Science at Durham University, where he leads the Scientific Computing research group and serves as the Director of Durham’s Institute for Data Science (IDAS). After studying Computer Science with a minor in Maths, he earned a Dr. rer. nat. (PhD) as well as a habilitation in Computer Science from TUM. Tobias has been the inaugurate director of the Master in Scientific Computing and Data Analysis (MISCADA), he is the PI on multiple HPC projects tied to the UK’s exascale programme ExCALIBUR, and he heads the UK’s first Intel oneAPI Centre of Excellence. He also serves as Domain Panel Chair (Artificial Intelligence) for EuroHPC JU.

He is particularly interested in efficient ways how to translate state-of-the-art algorithms – multigrid, higher-order DG or SPH formalisms – into fast code that fits to modern architectures, and how to create performance-portable algorithms and code. Where possible, his work feeds into open source software. This software has to challenge modern hardware and software stacks, including compilers, tools, and runtimes, while demonstrating how we can obtain better insights more efficiently from modern technology by exploiting systems creatively and employing the latest numerical schemes.

In his role as Director of IDAS, Tobias is particularly interested in upskilling Digital Research Technology Professionals (RTPs). He champions several large grants within the UK’s Digital Research Infrastructure initiative that focus on skills development (including CAKE, SHAREing, and HAI-End), and is therefore heavily involved in creating advanced upskilling materials for HPC, developing novel training formats, and establishing a productive and efficient HPC software and service landscape.

  • 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/
