The Cray User Group (CUG) facilitates collaboration and information exchange across the high-performance computing (HPC) community.  You and your colleagues from CUG Member sites around the world hold the key to sustaining this conference as an invaluable source of information and technical interchange.

We invite you to present at the CUG 2025 May 4 – 8, in New York, NY. If you are not from an active CUG member site, please read the “Attending a CUG Meeting” section at https://cug.org/events/.

CUG is not only about computing, it represents users across all inter-connected and inter-related HPC disciplines, including computing, storage, and analytics.

CUG2025 includes several different technical program elements:

        Paper
            Full-length abstracts presenting novel results
            Submissions in this track will require a final paper
            Will be given priority for available slots
            Will be considered for publication in a ACM International Conference Proceedings Series.
        Presentation
            Submissions in this track are intended to be “presentation-only”
            do not require a final paper submission, but a final version of slides will be required
            not considered for publication in the journal
        Birds of a Feather (BoF)
            Submissions in this track should prioritize interactivity
            Submissions of this type often include: presentations, panel discussions, and Q&A sessions
            Consider if another group will submit a similar BoF and if you should merge proposals
        Tutorial
            Submissions should justify the desired length of the tutorial, half-day (3 hours) or full-day (6 hours)
            “Hands-on” tutorials are encouraged to give attendees the chance to try exercises/demo during the tutorial
