We are pleased to invite you to the HACE 2026 Workshop – HPC/AI Convergence and Exascale, which will take place in Toulouse, France, from 26 to 28 May, 2026.
Building on the opening conference SCOPE on « HPC and AI convergence at the Exascale era », HACE 2026 will explore how hybrid AI–HPC workflows can deliver robust and scalable solvers for complex physical and industrial applications. The workshop will address methodological advances — including Physics-Informed Neural Networks (PINNs), Neural Operators, diffusion models, and foundation models — alongside large-scale implementations and real-world application case studies. This workshop is part of the AISSAI thematic trimester on « HPC and AI convergence at the exascale era. »
You can find the programme and access to the registration platform here: https://aissai-hace.sciencesconf.org/.
We are delighted to announce a strong lineup of invited speakers, covering both methodological foundations and application-driven talks across three days, among others:
- Alena Kopanikacova (PINNs: theoretical and algorithmic advances)
- Nikola Kovachki (Neural Operators)
- Jean Kossaifi (Neural Operators: applications)
- Nilo Schwencke (applications of AI-based surrogates)
- Bruno Raffin (AI/HPC coupled workflows)
- Tobias Grosser, University of Cambridge (MLIR-based approaches)
- Edouard Oyallon (training at scale)
- Olivier Beaumont (training at scale)
- Fanny Lehmann, ETH Zurich (foundation models for geophysical sciences)
- Youngdoo Choi (generative models for scientific applications)
- Laure Raynaud, Météo-France (AI for weather and climate)
- Alban Farchi, ECMWF (AI for numerical weather prediction)
- Andreas Lintermann (AI for computational fluid dynamics)
- Oriol Lehmkuhl (AI-driven simulations)
- Philipp Krah
- Benoît Malézieux
The programme combines keynote talks, focused application sessions, panel discussions, and hands-on technical sessions. A panel dedicated to benchmarking AI-based methods — from PINNs to foundation models — will bring together speakers across the workshop days.
HACE 2026 has been preceded by the SCOPE opening conference and is followed by the GAP workshop on inverse problems in physical science (Grenoble, 17–19 June 2026) and a Hackathon dedicated to AI/HPC convergence using the JAX programming framework (Orsay, 20-23 July 2026).
