About the Meeting

The Oak Ridge Leadership Computing Facility (OLCF) will hold its annual OLCF User Meeting October 17-18, 2023. The purpose of the user meeting is to share selected computational science and engineering achievements emerging from the OLCF’s user programs, to enable interactions among users, to advance the OLCF’s relationships with our user community, and to highlight computational requirements for the future. The 2023 meeting will feature OLCF facility updates, user-experience talks from teams running on early Frontier hardware, and deep dive discussions with OLCF staff.

Visiting ORNL

Upon your arrival at one of the Bethel Valley Road entrance stations, have a compliant form of identification ready for the Protective Force officers so that they can quickly confirm you with the list. If you do not have a compliant form of identification, you will be allowed past the entrance station, but will be required to report to the ORNL Main Visitor Center where your host will need to meet and escort you for the duration of your visit.

Foreign national visitors must always present a Visa and Passport upon arrival at the ORNL Main Visitor Center or the Chestnut Ridge Visitor Center.

Follow the signs directly to the ORNL Main Visitor Center to receive your visitor badge.

  • Rental cars are recommended. If you need to call for a taxi or rideshare service (e.g., Uber and Lyft), we kindly ask you to verify that the driver will be a U.S. citizen or has a valid ORNL badge to prevent delays or entry failures.
