Berkeley Lab staff will be in St. Louis, Missouri, for SC25, the premier conference on high-performance computing, networking, and storage. Running from November 16 to 21, the event will feature Berkeley Lab researchers presenting talks, posters, tutorials, workshops, panels, Birds of a Feather sessions, demos, and more. The Department of Energy’s booth (#3802 in the exhibit hall) will showcase talks, demos, roundtables, and videos highlighting Berkeley Lab collaborations.
SCinet, the high-speed network supporting the event was built with contributions from Berkeley Lab engineers, including ESnet and NERSC staff. ESnet has been recognized as a Diamond contributor for its ongoing support of SCinet.
Below is a continually updated day-by-day guide to SC25 programming featuring Berkeley Lab staff and resources. All times are in Central Standard Time. If you spot an error or omission, please email [email protected].
