Event Description

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 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.

Submission Guidelines

If you are interested in presenting a talk, or technical session, please submit a short abstract by Friday, March 14, 2025, AoE via EasyChair. While in-person presentations are preferred, live online presentations will be allowed in exceptional cases. Published or work-in-progress research in respective areas is encouraged and presenters retain the right to publish elsewhere. All final presentations are due by April 11, 2025, AoE.

Topics of Interest

• Application characterization on Intel platforms: Intel® Xeon® CPUs, Intel® Gaudi® AI accelerators, Intel GPUs, etc.), CXL-attached memory, etc.
• Experiences with incorporating machine learning and deep learning in HPC applications and workflows including surrogate modeling, foundational models, augmented experiment design, etc.
• Performance analysis, optimization, and best practices, and implications of HPC and HPC-AI workload behavior on system design at extreme scale (power, reliability, scalability, performance, processor design)
• Memory system, I/O, interconnects (PSM2/3, OPA, ethernet)
• Software environments and tools for computing at extreme scale (instrumentation, debugging/correctness, thread and process management, libraries and language development)
• Experience using extreme scale systems: usability, in-situ visualization, programming challenges, algorithms and methods, etc.
• Site updates from existing and forthcoming systems

Important Dates (Updated)

• Presenters’ confirmation and consent deadline: April 10, 2025, AoE
• Final presentations due from speakers: April 11, 2025, AoE
