OLCF User Meeting (Jun 22-24)
The OLCF will hold its annual User Meeting remotely from June 22-24, 2021. 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 2021 meeting will feature OLCF Facility updates, user-experience talks on Summit and Frontier early hardware, deep dive discussions with OLCF staff, and OLCF executive board election results. For more information or to register, see https://www.olcf.ornl.gov/calendar/2021-olcf-user-meeting/
