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.

- The CFP for #PPAM2026 is out. Always one of the best conferences in the field with an outstanding cultural programme on top: ppam.edu.pl https://ppam.edu.pl/
- Most of it is German, but there's always some English content in there as well. And it is nice to learn about the new computer Lion Cubs, as well as to see the HPC Days featured: https://www.cs.cit.tum.de/sccs/weiterfuehrende-informationen/quartl/
- Our Correctness & Debugging workshop came to an end on Monday, and we have summarised the outcomes at https://shareing-dri.github.io/events/202511-correctness-workshop/ We'll certainly run one or two more of these events within the HAI-End project, and use the insights to feed into @shareing.bsky.social
- Paper alert: arxiv.org/abs/2512.05516 In this paper, we extend our concept to let a compiler offload kernels to the GPU through annotations (so similar to OpenMP pragmas). Previously, it converted data SoA and rewrote the compute kernels automatically to work only on these slimmed down data views. https://arxiv.org/abs/2512.05516
- Congrats to our @durham-comp-sci.bsky.social students for representing Durham Uni successfully at #CIUK2025 's cluster competition, with posters, volunteering, and ... HPC rulez
