SUMMARY:MS6F - Application Perspective on SYCL, a Modern Programming Model
  for Performance and Portability
DESCRIPTION:HPC and data-intensive computing now stand as the fourth pilla
 r of science. The heterogeneous architectures, primarily GPUs, are a stapl
 e of HPC. However, the fast pace of development and increasing diversity o
 f hardware bring forth not only new opportunities, but also challenges. Pr
 oprietary heterogeneous programming models often pose risks due to vendor 
 lock-in, hurting collaboration and limiting portability, hence undermining
  reproducibility in scientific research. SYCL, a vendor-agnostic, C++-base
 d standard for heterogeneous computing with several mature implementations
  for a wide range of hardware accelerators, offers a promising path toward
 s vendor-agnostic, high-performance computing. This minisymposium focuses 
 on the experiences of scientific application developers using SYCL as a pe
 rformance-portability solution across different hardware accelerators, fos
 tering a collaborative open-software ecosystem. The talks will focus on be
 st practices for developing performance-portable and maintainable code usi
 ng SYCL, as well as on co-development and interaction between the SYCL Wor
 king Group and application developers. The aim of this workshop is to cont
 ribute to the wider adoption of open standards in scientific computing.\n\
 nExperiences with Using SYCL for NWChemEx on Exascale Supercomputers\n\nTh
 e rise of exascale computing offers new possibilities for computational ch
 emistry, particularly in modeling molecular systems. We examine the integr

 cs Using SYCL\n\nShamrock is a native SYCL-based framework designed for nu
 merical astrophysics on exascale architectures. Developed in C++17, Shamro

 elopment at HPC Scale\n\nThe vendor-agnostic SYCL standard provides a C++-
 based foundation for the development of applications targeting heterogeneo
 us systems. However, while SYCL supports multiple devices in a single shar
