The 2025 Exa-SofT Annual Assembly took place from 5 to 7 November, 2025, bringing together 65 researchers and engineers from academia and industry to discuss the latest progress, prepare the milestones of the work packages, and welcome the latest recruits.
Exa-DoST (Data-oriented Software and Tools for the Exascale) is one of the five projects of the NumPEx program. Exa-DoST will address the major data challenges by proposing operational solutions co-designed and validated in French and European applications. This will allow filling the gap left by previous international projects to ensure that French and European needs are taken into account in the roadmaps for building the data-oriented Exascale software stack.
Finally, Exa-DoST was proud to welcome its new recruits, who rose brilliantly to the challenge of presenting scientific highlights in plenary sessions and via poster sessions !
