The General Assembly of the Exa-MA project took place at the University of Strasbourg on January 14-15, 2025. This two-day event was an opportunity to share the latest advancements of the project, strengthen collaborations between Work Packages (WPs), and discuss the next steps.

Exa-MA aims to revolutionize methods and algorithms for exascale scaling: discretization, resolution, learning and order reduction, inverse problem, optimization and uncertainties. We are contributing to the software stack of future European computers.
The General Assembly gathered 83 participants, including members of the Scientific Board, external partners, and young recruits, with 15 joining online. The event featured plenary sessions, thematic workshops, and strategic discussions focused on intra- and inter-project synergies, particularly with Exa-Soft and Exa-DI. Key topics included AI, accelerators, software sustainability, and external collaborations. Strengthening ties with academic and industrial partners was also a major focus, reinforcing Exa-MA’s role in the broader exascale computing ecosystem.
