IXPUG Annual Conference 2025 will shift to a one-day virtual meeting of HPC and AI experts featuring keynotes, tech talks, lightning talks, and more. The meeting will still be hosted by Texas Advanced Computing Center (TACC) but will be online via Zoom on Tuesday, April 15. The event welcomes software developers, scientists, researchers, academics, systems analysts, students, and end-users who want to share with and learn from our vibrant, global community via technical discussion and networking. Challenges surrounding application performance and scalability will be covered across all levels, including tuning and optimization of AI and HPC workloads and applications. Topics are wide-ranging, including system hardware beyond the processor (memory, interconnects, etc.) and accelerators (e.g., GPUs, AI accelerators) as well as topics related to open standards, oneAPI, software tools, programming models, OPEA, PyTorch, and more. Key themes: latest advancements in high performance computing, heterogeneous computing, artificial intelligence, visualization, memory, I/O, and storage.

The event will feature multiple sessions related to the ALCF’s Aurora exascale supercomputer:

• OpenMP in oneAPI: Empowering Scientific Computing on Intel Platforms, From Laptop to Aurora Exascale Supercomputer, Presenter: Jeongnim Kim, Intel Corporation, Co-Authors: Patrick Steinbrecher and Xinmin Tian, Intel Corporation and Ye Luo, Argonne Leadership Computing Facility, Argonne National Laboratory
• Scaling Molecular Dynamics Simulations on Aurora with NAMD, Authors: David Hardy and Eric Bohm, University of Illinois at Urbana-Champaign; Ke Yue, Intel Corporation; Wei Jiang, Argonne National Laboratory
• Leveraging HIP on Intel PVC, Presenter: Brice Videau, Argonne Leadership Computing Facility, Argonne National Laboratory
• Multi-Scale Light-Matter Dynamics in Quantum Materials on Aurora PVC, Presenter: Nariman Piroozan, Intel Corporation
