MultiXscale experts Céline Merlet and Lara Peeters have been featured in the SC25 HPC Ignities Women’s History Month, a special issue that highlights contributions of women working in the field of HPC. Since 2023, this program showcased over 150 experts, among pioneers, leaders and students whose work continues to inspire the next generation. More information is available on the blog post “Women Igniting Innovation in HPC” here.

MultiXscale experts will give the following talks during the 10th EasyBuild User Meeting, to be carried out this week in Jülich, Germany: Thursday 27 March 2025(focused on EESSI) EasyBuild is a software build and installation framework that allows you to manage (scientific) software on High Performance Computing (HPC) systems in an efficient way. The EasyBuild User Meeting is an open and highly interactive event that provides a great opportunity to meet fellow EasyBuild enthusiasts, discuss related topics, and learn about new aspects of the tool.

The “Portable test run of ESPResSo on EuroHPC systems via EESSI” article has been published on Procedia Computer Science on 7th March 2025.  The document is available through this link: https://www.sciencedirect.com/science/article/pii/S1877050925006283 Abstract: One of the milestones of the EuroHPC Centre of Excellence MultiXscale is to be able to run the EESSI test suite on at least two different architectures available on EuroHPC Supercomputers. Our initial efforts focused on making the test suite portable across two different supercomputers: Karolina and Vega (the CPU partitions of both are a Zen2 micro-architecture).More recently we have spent time getting the same test suite working on a more “exotic” architecture, the ARM A64FX architecture of Deucalion (which was in pre-production at the time of the experiment). This has raised some additional complications for EESSI as CernVM-FS (which is used to distribute EESSI) was not yet natively available there.We show the current scalability of the ESPResSo application using the portable test suite. ESPResSo is already known to have scalability issues for both multi-node and multi-GPU configurations which are currently being analysed in collaboration with the POP Centre of Excellence. The purpose of this effort was to ensure that we can quickly and automatically record the performance of the application across a range of EuroHPC systems (i.e. ESPResSo acts as a pilot application for the full test suite)

Several partners of the MultiXscale Center of Excellence will be involved in the EuroHPC Summit 2025, to be carried out at the ICE Congress Centre, in Kraków (Poland) from Tuesday 18 to Thursday 20 March 2025. We will participate in the following sessions: We are looking forward to enjoying a week full of insightful discussions! See you in Kraków next week!

This week, we celebrate the International Women’s Day 2025 (8 March) by featuring the amazing women involved in our MultiXscale Center of Excellence. They explain, in their own words, their roles and contributions to the project. Discover our cohort of professional women here below and using the hashtag #WomenAtMultiXscaleCoE on our social media profiles: Facebook, X, LinkedIn and Bluesky.

We are pleased to invite you to the workshop Modeling & Simulation of Fluid-Structure Interactions Across Scales, taking place on April 8–11, 2025, at National Institute of Chemistry, Ljubljana, Slovenia.This workshop will bring together experts and researchers to discuss recent advances in hydrodynamics modeling, multiscale coupling methods, AI-driven approaches, large-scale simulations, and HPC technologies. The program will feature lectures, discussions, and hands-on sessions covering: Invited Speakers: The workshop is free of charge.

Abstract submission for poster presentations is open until March 14, 2025. Looking forward to your participation!

A couple of weeks ago the EuroHPC Joint Undertaking (EuroHPC JU) announced the consortium that will develop the EuroHPC Federation Platform (EFP). This ambitious effort will deliver a ‘one-stop shop’ for researchers using the EuroHPC supercomputers, as well as the upcoming EuroHPC AI Factories and quantum computers, built with open source software. Ghent University is part of this consortium to integrate EESSI into the EuroHPC Federation Platform as common software stack. Henrik Nortamo (CSC), the technical lead of the EFP consortium, gave an excellent 20-minute talk on EFP last weekend in the 10th HPC, Big Data, and Data Science devroom at FOSDEM’25 in Brussels. Slides and recording of the talk are available here. The EFP consortium¶ The consortium that will develop the EuroHPC Federation Platform consists of: A productive kickoff meeting was held on 16+17 January 2025 in Helsinki, Finland. Each of the components of the federated platform were presented by and to the consortium partners, and practical aspects of executing the planned work in the coming months and years were discussed. * Read full article here

EESSI (European Environment for Scientific Software Installations) has been used in an ESiWACE CoE webinar on Extrae + Paraver. ESiWACE3 CoE and the National Competence Center for HPC in Austria organized the training event “Extrae and Paraver: Profiling Weather and Climate Applications” on January 27, 2025, as part of the CASTIEL2 Training Sprint. The course focused on the BSC performance analysis tools (widely used in POP3 CoE), which are a set of different tools to support developers in the evaluation, tuning, and optimization of their codes. EESSI provided the installations of such tools, in a collaboration between MultiXscale CoE and ESiWACE CoE.

NRIS Talks videos are already available on the YouTube channel. NRIS (Norwegian Research Infrastructure Services) is organizing webinars as part of it’s outreach program NRIS Talks. This webinar aims to provide a comprehensive overview of how to build software on top of the scientific software stack provided by the European Environment for Scientific Software Installations (EESSI). About the Webinar: We explain and demonstrate how everyone can easily build and install software on top of EESSI. While EESSI already provides ~ 500 software packages a specific software you need may not be available through EESSI yet. The webinar shows how to use EasyBuild to build (scientific) software on top of EESSI for all users, for a specific project account or individual users.

MultiXscale CoE will gather top European experts in High-Performance Computing (HPC) from academic and industrial sectors across Europe during its General Assembly (GA), to be carried out from 23rd to 24th January 2025 after the HiPEAC event in Barcelona (Spain), where the completed activities and future work in the 3rd year of the project will be discussed in this two-days meeting.  Previously to their GA, MultiXscale experts will be involved in several sessions during the HiPEAC conference in Barcelona, the premier European forum for experts in computer architecture, programming models, compilers and operating systems for general-purpose, embedded and cyber-physical systems. These sessions are:  Funded for a period of four years, and coordinated by the National Institute of Chemistry based in Ljubljana, Slovenia, MultiXscale is a collaborative project between members of the CECAM network and EESSI that will allow domain scientists to take advantage of the computational resources offered by EuroHPC JU. It gathers the following 13 partners joining from the academic and industrial sectors across Europe: National Institute of Chemistry, Forschungszentrum Jülich GmbH, University of Stuttgart, University of Barcelona, SURF BV, University of Groningen, Ghent University, University of Bergen, Barcelona Supercomputing Center, Sorbonne University, HPCNow!, Leonardo and the Italian Institute of Technology.  *Download press release in pdf here
