Collaboration plan with definition of common objectives and activities including milestones. Deliverable D7.1 of the HORIZON-EUROHPC-JU-2021-COE-01 project MaX (101093374)

MAX - MAterials design at the eXascale (GA 101093374) is a Centre of excellence for HPC applications funded in the joint EuroHPC-Horizon Europe call. It develops and uses its lighthouse (quantum simulation) codes to enhance the understanding, predicting, and discovering of the properties and performance of materials, to address the HPC-ecosystem challenges, to leverage the opportunities arising from future exascale and post-exascale architectures, and to offer powerful paths to discovery and innovation serving both scientific and industrial applications.In this endeavour, MaX will collaborate with the complementary projects and the dedicated Coordination and Support Action (CSA) CASTIEL 2 (Grant No 101102047) by developing the following activities:● Actively contributing to the coordination activities of CASTIEL 2● Contributing to the knowledge pool and available information in the common portal C2ISS● Establishing effective collaborations and jointly addressing cross-cutting issues● Participating in regular meetings to plan, implement and monitor collaborations and to synchronise research and development activities● Participating in benchmarking exercises● Sharing results and best practices as relevant● Joint publication and dissemination of results● Joint events● Actively contributing supported lighthouse codes to a common continuous integration and application deployment platform with automated testing (e.g., using Special Access scheme in collaboration with CASTIEL 2) at least on all EuroHPC JU systems, provided that a suitable IT infrastructure and access agreements are put in place by EuroHPC JU● Establishing common best practices for IP management and development including effective measures to ensure code quality, reviews, testing, management and development cycles● Actively advancing modularisation: implementation of concrete measures for identification of common routines/algorithms/modules, creation and extension of software libraries used by multiple codes across disciplines.This deliverable shows how, at Month 6, we plan to implement these activities.
