2018 OLCF User Meeting Attendees

The Oak Ridge Leadership Computing Facility (OLCF) is pleased to announce the 2018 OLCF User Meeting will be held May 15-17 at Oak Ridge National Lab in Oak Ridge, TN.  The purpose of the annual user meeting is to share selected computational science and engineering achievements emerging from OLCF’s user programs, to enable direct interactions among users, advance OLCF’s relationships with our user community, and highlight computational requirements for the future.

The 2018 meeting will feature paired talks from OLCF users and application developers. This is an opportunity for users to share their scientific accomplishments and state-of-the-art computational development methods.  The meeting will also feature plenary talks, panels, and center updates from the OLCF staff.


Other highlights include:

Poster Session:  We invite you to participate in an OLCF poster session and share your project’s achievements to date.

 Tour:  Attendees will also be offered a tour the OLCF Facility, including stops at the observation area to see Titan, Summit, and a stop at EVEREST, the OLCF scientific analysis and visualization laboratory.

 OUG Elections:  Elections will be held during the OLCF User Meeting for the open spots on the OLCF Executive Board User Group.  The OLCF User Meeting is open to current and future users.  More information about elections will be forthcoming.

 Attending via Webinar:  For participants who cannot attend on-site, a BlueJean event has been set up.  Please follow instructions below to attend:
