SUMMARY:MS2B - Hardware–Software Co-Design for Trustworthy Digital Twins i
 n Fusion Energy Research
DESCRIPTION:Access the recording\n\nOrganizer(s): Gilles Fourestey (EPFL),
  and Filippo Spiga (NVIDIA Corporation)\n\nThis minisymposium explores how
  integrated co-design strategies strengthen confidence in computational mo
 dels for fusion energy. It examines how GPU-accelerated architectures enha
 nce the reliability and reproducibility of digital twins for plasma physic
 s. Fusion energy research combines complex multi-physics phenomena with AI
 -driven models, requiring convergence between hardware innovation, softwar
 e optimization, and scientific validation. The session brings together exp
 erts from academia, industry, and major European programmes to highlight c
 o-design efforts that balance simulation scalability with scientific integ
 rity. Via the contributions of EUROfusion partners (SCITAS and CINECA) and
  the technology partner NVIDIA, this minisymposium will discuss GPU-enable
 d advances in plasma modelling, uncertainty quantification, and digital tw
 in fidelity. The discussion emphasizes verification, validation, and repro
 ducibility as foundational to scientific trust in high-performance fusion 
 research. The session aims to demonstrate concrete co-design pathways from
  hardware to scientific validation, establish a reference architecture for
  trustworthy digital twins applicable beyond fusion, foster collaboration 
 among HPC engineers, domain scientists, and AI experts, and produce action
 able guidelines enhancing reproducibility and transparency in co-designed 
 HPC applications.\n\nFrom Physics to Hardware: Co-Designing Fusion Codes f
 or Exascale Systems\n\nPlasma fusion releases massive amounts of energy, m
 aking it an important area of research for future energy production. Howev
 er, the experimental devices required to study magnetically confined plasm
 as are extremely expensive. Numerical simulations are therefore a crucial 
 tool for studying such syst...\n\n\nEmily Bourne (EPFL), Virginie Grandgir

 n), Matthieu Protais (CEA), and Pauline Vidal (Max Planck Institute for Pl
 asma Physics)\n---------------------\nThe Fusion Digital Twin: Integrating
  Databases, Simulation, AI Surrogates and Visualization for Design Workflo
 ws of Fusion Devices\n\nDesigning elements for nuclear fusion devices is a
  challenge at the crossroads of engineering and HPC, requiring data from s
 imulation codes, experimental databases, and engineering tools. Previous w
 ork shows that separate applications of heterogeneous software greatly com
 plexify the engineering anal...\n\n\nFlorian Cabot (EPFL)\n---------------
 ------\nIntegrating AI into Trustworthy Workflows for Digital Twins. A Fus
 ion Perspective\n\nAdvances in high-performance computing (HPC) and artifi
 cial intelligence (AI) are transforming how complex, multidisciplinary sci
 ence problems are addressed. Fusion is one of those domains waiting to be 
 disrupted. Historically, theory, engineering and operations were living in
  different silos, each ...\n\n\nPeter Messmer and Filippo Spiga (NVIDIA In
 c.) and John Stone (NVIDIA Inc)\n---------------------\nBuilding Trust in 
 Fusion Science through Co-Designed HPC Infrastructure\n\nFusion is regarde
 d as a sustainable and almost infinite source of energy, making it essenti
 al for the future energy landscape. Achieving controlled fusion requires a
  deep understanding of the plasma in which fusion reactions occur. However
 , the plasma processes involved span multiple spatial and tem...\n\n\nNiti
