EESSI CI/CD hackathon Provided by EuroHPC CoE MultiXscale in collaboration with CASTIEL2 and EuroCC DenmarkThe hackathon will give a general introduction to CI/CD, and then focus on the specific issues that can affect CI/CD workflows in the HPC domain. It will introduce the European Environment for Scientific Software Installations (EESSI, https://eessi.io) and some of the tools that EESSI is creating to help to address these issues.Ample time will be provided for participants to follow prepared examples, as well as time to investigate the implementation of some of the practices for their own application codes.The session will be recorded. Recordings, slides, and materials used will be made publicly available shortly after the event via this page.SessionsThursday 02 October 2025 (09:30-16:00 CEST): EESSI CI/CD hackathonVenueThe event will take place at the Royal Danish Library's Cultural Centre, in the Black Diamond building.Online participation is available via Zoom.FormatHybrid formatSpace for 25 in-person attendeesOnline participation via ZoomMix of presentation & hands-on exercises~2.5h of content~2.5h for hands-on~30min for final Q&ARegistrationBoth in person and online attendance is free of charge, but registration is required.Register via https://event.ugent.be/registration/eessi202510 « All Events EESSI CI/CD hackathon October 2 @ 9:30 am - 4:00 pm Website: https://www.eessi.io/docs/training-events/2025/hackathon-eurohpc-user-days/ Black Diamond Søren Kierkegaards Plads 1 Copenhagen, 1221 Denmark + Google Map Add to calendar Google Calendar iCalendar Outlook 365 Outlook Live EESSI Happy Hour session

Systematic coarse-graining and machine learning in soft matter physics with ESPResSo This school will teach coarse-graining, reverse coarse-graining, chemical space exploration, machine learning descriptors, machine-learned effective potentials, reinforcement learning, soft matter physics, and lattice-Boltzmann hydrodynamics. Lectures will provide an introduction to the physics and model building of these systems as well as an overview of the necessary simulation algorithms. During the afternoon, participants will practice running their own simulations in tutored hands-on sessions using the software ESPResSo. Many of the lectures and hands-on sessions will be taught by developers of the software. Hence, the school will also provide a platform for discussion between developers and users about the future of the software used in the hands-on sessions. Moreover, users can get advice on their specific simulation projects. Time will also be dedicated to research talks, which illustrate how the simulation models and software are applied, and which provide further background on simulating soft matter at different length and time scales.
