The hybrid event welcomes users and non-users of the OLCF.

The Oak Ridge Leadership Computing Facility, a Department of Energy Office of Science user facility at Oak Ridge National Laboratory, will host its 19th annual user meeting on October 17-18, 2023.

For the first time in three years, the meeting will have in-person attendance at ORNL. Attendees may also register to attend virtually. The user meeting has been held online since 2020 due to COVID-19 restrictions. The event is free and open to both users and non-users interested in learning more about the OLCF.

“We are excited to welcome back OLCF users to ORNL, where we can use the time to have deeper engagements with our user community and showcase many of our OLCF resources,” said Ashley Barker, section head for operations in the National Center for Computational Sciences at ORNL. “We realize that travel is not always accessible to everyone, so we are working diligently to make most of the meeting available to those who cannot attend in person.”

This year’s event will include several sessions on Frontier, the world’s fastest supercomputer, including system updates and user experience talks from experts at ORNL, AMD, Whisper Aero, the University of California San Diego, and GE. Attendees will also hear the latest news about the facility’s next supercomputer, OLCF-6.

The meeting will also include lunch-and-learn sessions and deep-dive discussions with OLCF experts on topics ranging from scalable protected infrastructure and federated learning to performance portability.

Onsite attendees can tour Frontier and Summit facilities and attend a poster session that highlights notable research from the OLCF user community.

The registration deadline is September 15, 2023. All participants are encouraged to contribute a poster for the poster session on October 17. Poster submissions are due by October 11, 2023.
