SUMMARY:MS4A - Performance-Portable High-Order CFD for Digital Twins on He
 terogeneous Exascale Architectures
DESCRIPTION:Organizer(s): Dominik Obrist (University of Bern)\n\nThe emerg
 ence of Digital Twins and large-scale computational design is reshaping hi
 gh-performance scientific computing, demanding scalable, trustworthy, and 
 hardware-extensible solutions. This minisymposium brings together advances
  in high-order computational fluid dynamics (CFD) and compiler technologie
 s that enable performance portability across heterogeneous CPU–GPU archite
 ctures. The three presentations highlight complementary strategies—softwar
 e architecture, scalable optimization frameworks, and compiler-driven kern
 el generation—for building next-generation, performance-portable CFD and d
 esign tools for heterogeneous exascale systems. The minisymposium will con
 clude with a podium discussion on future directions in this field.\n\nNext
 -Generation Digital Twins: C++-Based Solvers Across CPUs and GPUs\n\nDigit
 al Twins are rapidly becoming a key driver of industrial innovation in sec
 tors such as automotive and aeronautics, placing stringent demands on comp
 utational physics solvers for performance, portability, and long-term main
 tainability. Meeting these demands requires more than efficient algorithm.
