We’re just a week away from the annual International Conference for High Performance Computing, Networking, Storage, and Analysis 2023 (SC23), and Berkeley Lab Computing Sciences Area (CSA) staff are making their way to Denver to meet with colleagues, peers, and industry to connect, collaborate, and exchange expertise. The event begins Sunday, November 12, and runs through Friday, November 17.
CSA researchers, scientists, and engineers participate in tutorials, workshops, panels, technical papers, and posters as part of the conference’s technical program. In addition, the U.S. Department of Energy’s (DOE) booth – which showcases the 17 DOE national laboratories – will feature high-level talks and technical demonstrations from the labs throughout the three-day exhibit hall component of the event (November 14-16).
Connecting all the demos and booths to the outside world is the network known as SCinet, which at 6.71 Tbps, will temporarily be the most powerful and advanced network on Earth. Multiple network engineers from CSA’s ESnet and NERSC teams are part of the volunteer workforce that designs, builds, tests, and operates SCInet over the course of the year leading up to and through the conference.
Notable events include:
-
- “I Am HPC” Plenary Session - Panel discussion includes Kathy Yelick, Monday, Nov. 13, 5:30 - 6:45 p.m., Mile High Ballroom
- Featured Presentation, NERSC Director Sudip Dosanjh: “The Next 50 Years: How NERSC is Evolving to Support the Changing Mission Space and Technology Landscape,” Tuesday, Nov. 14, 2:30 p.m., DOE booth #243
- SC23 Network Research Exhibition. Using SciNet, numerous technical demonstrations will take place in booths around the exhibit hall during SC23
- Student Cluster Competition, Monday-Wednesday, Nov. 13-15
- Top500 presentation, Tuesday, Nov. 14, 5:15 – 6:45 p.m.
- Gordon Bell Prize Awards, Thursday, Nov. 16, 12:45 - 1:30 p.m., Mile High Ballroom
