Understanding these systems requires a multiscale approach that integrates knowledge from various levels of organization, from molecular interactions to macroscopic behavior. This approach is crucial for tackling challenges in diverse fields such as bioliquids, energy storage devices, and helicopter dynamics. In the realm of bioliquids, such as biomolecules and cellular components, multiscale modeling plays a pivotal role in unraveling the complexities of biological processes. From protein folding to membrane dynamics, researchers employ techniques ranging from atomistic simulations to coarse-grained models to capture the intricate interplay of molecules within cellular environments. These models not only enhance our fundamental understanding of biological systems but also have practical applications in drug design and personalized medicine. Similarly, the design and optimization of batteries demand a multiscale perspective to address issues ranging from electrode materials to system-level performance. Atomistic simulations provide insights into the behavior of ions and electrons within electrode materials, guiding the development of novel chemistries with enhanced energy storage capabilities. Meanwhile, continuum models facilitate the prediction of battery performance under various operating conditions, aiding in the design of safer and more efficient energy storage devices. In the field of helicopter dynamics, multiscale modeling enables engineers to simulate the interaction between aerodynamics, structural mechanics, and control systems. By integrating these disparate disciplines, engineers can optimize helicopter design for improved performance, maneuverability, and safety. Despite significant advancements, multiscale modeling of complex systems still faces challenges. Bridging the gap between different scales, accurately representing system dynamics, and incorporating uncertainty remain areas of active research. Furthermore, the increasing complexity of modern systems demands innovative computational techniques and interdisciplinary collaboration. In conclusion, the state of the art in multiscale modeling and simulation of complex systems encompasses a diverse range of applications, from bioliquids and batteries to helicopters. By integrating knowledge across multiple scales, researchers strive to unravel the mysteries of nature, optimize technological innovations, and address pressing societal challenges.

“OOD Meets EESSI: Accessing and Distributing Scientific Software with Ease” by our HPC experts Christian Bustelo and Arturo Gimeno at Global Open OnDemand Conference -GOOD2025🗓️ 19 March, from 9h30 to 09h55 (US/Eastern).📌 Tsai Auditorium (CGIS S010), Harvard University (USA) Abstract: This presentation will provide an overview of the EESSI project and its objectives, as well as our plans to integrate it into the OOD platform. This will allow for combined easy access to both scientific software and HPC resources in a single platform. In the HPC space there is a push to improve accessibility and lower the entry barrier to users. Thus, they can focus solely on science and not deal with the intricacies of HPC systems, which can be pretty obscure to non HPC experts. The OOD platform is the result of such efforts and has become sort of a standard: many of the supercomputers around the world provide it as one of the ways to access and interact with the HPC system. OOD deals mainly with accessibility to the HPC resources, but there is another aspect to accessibility: scientific software availability. Installation of scientific software is rather complex, since it is not sufficient for it to work, but must also perform. Here enters the European Environment for Scientific Software Installations (EESSI) project, that provides a complete and optimized scientific software stack accessible from many different platforms: personal workstations, cloud and supercomputers. This allows users to work with the same software environment, regardless of the platform, OS, or architecture. Two distinct projects with different aims, but complementary: EESSI provides the scientific software and OOD the way to access it. More information here

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)
