Tobias Weinzierl is Professor in High-Performance Computing (HPC) in the Department of Computer Science at Durham University, where he leads the Scientific Computing research group, and the Director of Durham’s Institute for Data Science (IDAS). After studying Computer Science with a minor in Maths, he obtained 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.

    We had a very constructive kick off session for our 2025 performance analysis workshop series. Hope to be able to publish and share our insights and lessons learned soon.

    It has been a privilege, fun, and extremely productive scientifically to be part of ExCALIBUR due to multiple projects. There are still many papers to come that directly result from this programme. [contains quote post or other embedded content]

    It was great to have Prakash Murali from @cst.cam.ac.uk in our SciComp seminar today. Interesting ideas on full stack design in quantum computing.

    I realise we've never published our SIAM BGCE contribution on arXiv. Here it is: arxiv.org/abs/2504.15814 We study stationary black holes phrased as wave equations over an adaptive mesh. The solution should be stationary by definition, but it is subject to numerical instabilities. https://arxiv.org/abs/2504.15814
