Report on the setup of the MAX CoE. Deliverable D7.3 of the HORIZON-EUROHPC-JU-2021-COE-01 project MaX (101093374)

The deliverable D7.3 summarises the setting up of the MAX Centre of Excellence (CoE), established through the HORIZON-EUROHPC-JU-2021-COE-01 call for the four year period 2023-2026. The Centre was not created anew: it is actually based on two previous MAX CoE editions (H2020 2015-2018 and 2018-2022). We therefore move from that experience to address significant changes and new challenges that affect the CoE organisation. Among these, we point out the new consortium composition and the modified rules and objectives. Importantly, the CoE now lies within the EuroHPC Joint Undertaking and will therefore develop strong collaborations with its ecosystem and with the Castiel-2 CSA.This third phase of MAX allows the management team and the whole consortium to take advantage of the experience acquired, analyse strengths and weaknesses of the previous project phases, and to consolidate the management structure while implementing ad hoc corrections to take into account the new call requirements and the new consortium composition.In the deliverable we present the establishing of governing bodies; the internal organisation structure; activities performed within WP7 Management, including references to the initial collaboration with the Castiel2 CSA. A description of the KPIs as set by the consortium is also given and discussed.
