Are you interested in scientific software, HPC, and reproducible computing environments? Join us in Dublin for an exciting EESSI Hackathon on Friday, 25 September 2026, from 09:00 to 17:30 local time (IST, UTC+1). Taking place immediately after the EuroHPC User Days, held in Dublin from 22 to 24 September, the hackathon will offer a great opportunity to get hands-on with EESSI, exchange expertise, tackle challenges, and collaborate with fellow members of the HPC community. Whether you are already using EESSI or are keen to discover how it can simplify the deployment and sharing of scientific software across diverse computing environments, this is a great opportunity to learn, experiment, and contribute to the EESSI ecosystem. Don’t miss this opportunity to connect with the EESSI community and take your HPC software workflows to the next level! Provided by EuroHPC CoE MultiXscale in collaboration with the EuroHPC Federation Platform. Further information and registration available here.

Our MultiXscale expert Matteo Zanfrognini (Leonardo) will present “Corporate Development of a gpu-native lattice Boltzmann solver for turbulent flows simulations” in the framework of HPCSIM26 – Frontiers of High-Performance & Cloud Computing in Modeling and Simulation, on 17 September at 9h40, in Bologna (Italy). Further details available here.

The talk “Shared-memory parallelism and performance portability in the ESPResSo package for particle- and lattice-based simulations”, given by MultiXscale expert Jean-Noël Grad at deRSE26 Conference is already available online through this link.

On Friday 25 September 2026 (09:30-16:30 local time, UTC+1), an EESSI hackathon will be organised in the wake of the EuroHPC User Days which takes place 22-24 September 2026 in Dublin. Provided by EuroHPC CoE MultiXscale in collaboration with the EuroHPC Federation Platform The hackathon will be general in nature, but centred primarily on the needs of in-person participants. A detailed program will be added after initial registrations have taken place and discussions with those registrants. An expected general outline of the program is: More information available here

The recording of the talk and slides presentation given by MultiXscale expert Alan O’Cais (Ghent University) on 17th June 2026, in the framework of the event HPC Knowledge Portal annual meeting – HPCKP26 Barcelona, are already available on the website through this link. HPC Knowledge Portal annual meeting is a key global event for High-Performance Computing able to attract relevant professionals and main developers of leading software projects widely used by the HPC community. Abstract: The EuroHPC Federation Platform (EFP) serves as a secure “one-stop shop” designed to harmonize access to European supercomputing, AI, and quantum computing infrastructure. Driven by the EuroHPC Joint Undertaking, the EFP streamlines user onboarding and unifies fragmented cross-site workflows through centralized services like single sign-on (SSO), federated resource allocation, and interactive web tools. This talk introduces the architecture and core components of the EFP, with a dedicated deep dive into its Federated Software Catalog (FSC). Built upon the European Environment for Scientific Software Installations (EESSI), the FSC addresses hardware heterogeneity by serving a pseudo-uniform, highly optimized stack of scientific software, applications, and libraries natively across all federated supercomputers. Attendees will learn how the EFP and EESSI alleviate user friction during cross-system migration, explore the current status of supported CPU/GPU architectures, and view a demonstration of software and workflow portability in action.

MultiXscale and the ICP Stuttgart invite you to the 2026 ESPResSo summer school “Studying dynamics in soft matter and porous materials”, taking place on October 5-9, 2026 in Stuttgart, Germany. Attendance is free of charge. The call for poster abstracts is open until September 25, 2026. More information available here

MultiXscale CoE will be actively contributing to EuroHPC User Days 2026, taking place from 22–24 September 2026 in Dublin (Ireland) bringing together the European HPC community. As part of the event programme, MultiXscale experts will participate in an interactive session, deliver a hands-on showcase of EESSI, organize a parallel session about Chemistry and Material Sciences and present a poster. The interactive session will provide an opportunity for participants to engage directly with MultiXscale experts, explore the challenges and opportunities in scaling HPC workflows, and discuss approaches for improving access to advanced computing environments. Through open discussions and practical examples, attendees will gain insights into how modern HPC software ecosystems can support researchers and communities across Europe. The parallel session: Chemistry and Material Sciences will take place on Wednesday, 23 September from 14h to 15h30. Join us at EuroHPC User Days 2026 to discover how MultiXscale and EESSI are helping shape the future of HPC.

MultiXscale experts Matteo Zanfrognini and Antonio Sciarappa (Leonardo) will give “An introduction to the lattice Boltzmann method for industrial applications” (and hands-on session as part of it) during the CFD parschool, from July 12 to 17 2026, in Gran Sasso Science Institute, L’Aquila (Italy).
