The goal is to leverage innovative storage technologies and support complex hybrid workflows involving simulation, analytics, and learning, running at extreme scales across supercomputers interconnected to Clouds and Edge-based systems.<\/p>\n<p>The second annual meeting of the Exa-DoST project took place at Inria, in Rennes, on 18-19 September 2024. It gathered participants in the project (scientists, engineers, students) with the goal of providing a common, shared vision on the project\u2019s objectives, activities, and strategy. It also included specific workshops focused on identifying challenging application requirements in terms of data storage and analytics. For the first time, members of the ExaDoST Scientific Advisory Committee and of the Industrial and Technology Advisory Committee attended a global Exa-DoST meeting.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=\u00a0\u00bb1\/1&Prime;][vc_custom_heading uncode_shortcode_id=\u00a0\u00bb861884&Prime;]Mercredi 18 septembre 2024[\/vc_custom_heading][vc_column_text uncode_shortcode_id=\u00a0\u00bb207823&Prime;]The first day was dedicated to presentations providing an overview of the project\u2019s goals and activities in the various specific areas covered by the technical work packages.
