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 2027 May 9-13, in Houston, Texas. If you are not from an active CUG member site, please read the “Attending a CUG Meeting” section at https://cug.org/previous-events/.

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

CUG2027 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
  • Lightning Talk
    • Brief 5-minute presentation showcasing novel ideas, practical solutions, lessons learned, demos, or early-career contributions
    • Submissions in this track are intended to be “presentation-only”
    • Do not require a final paper submission and final version of slides
    • 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

• Storage
• Networking
• System Interoperability
• Non-traditional HPC system provisioning ( Cloud/K8s,…)
• Resiliency, Reliability, Availability, Scalability
• Cybersecurity, identity and access management
• HPC and Quantum Integration

• Account Administration
• Consulting
• Software stack (testing, management, integration, …)
• Software testing, management and integration
• Documentation
• Training
• User Support
• Outreach
• Cloud service integration
• Federated workload management

• Tuning and Performance (System and application side)
• Problem Determination and analysis
• Comparisons and benchmarking
• Configuration / Administration
• Usage Experiences
• Novel/Emerging Use-cases

Conference Best Paper Award

We will announce nominations from finalists and then award the conference’s best paper.  Only papers submitted by the Papers due date will qualify for further rounds of reviews to be selected for the best paper award.

ACM International Conference Proceedings Series (ICPS)

CUG will publish selected CUG papers in the ACM International Conference Proceedings Series(ICPS). Papers submitted by the due date will be reviewed for the proceeding publication. Note that publication in the proceeding may require an additional round of reviews.

The ACM ICPS follows an open access publishing model and many CUG member sites are already members of ACM Open. The CUG conference will defray any cost associated with publication that are not met by member sites existing membership in ACM Open.

Important note to authors about the new ACM open access publishing model

ACM has introduced a new open access publishing model for the International Conference Proceedings Series (ICPS). Authors based at institutions that are not yet part of the ACM Open program and do not qualify for a waiver will be required to pay an article processing charge (APC) to publish their ICPS article in the ACM Digital Library. To determine whether or not an APC will be applicable to your article, please follow the detailed guidance here: https://www.acm.org/publications/icps/author-guidance.

ORCIDs are Open Researcher and Contributor Identifiers. They are provided to researchers as unique identifiers to distinguish their research from that of others who may have similar names. ACM now requires that all authors provide their ORCIDs in order to complete the ACM eRights process and have their accepted submissions published in the ACM Digital Library. Registering is easy and takes less than five minutes. To register, visit https://orcid.org/register. If you are not sure if you already have an ORCID (as your institution may have signed you up for one), visit https://orcid.org/reset-password, select the ORCID iD option, enter your registered email address in the email field, and select the Recover Account Details button. ORCID will send you an email from reset@notify.orcid.org, letting you know your 16-digit ORCID identifier.

Further information may be found on the ACM website, as follows:
