SC25 – Oak Ridge Leadership Computing Facility

The 37th International Conference for High Performance Computing, Networking, Storage, and Analysis, or SC25, will be held in St. Louis, Missouri, November 16-21. The National Center for Computational Sciences, Oak Ridge Leadership Computing Facility, and Oak Ridge National Laboratory will once again play an active role in this premier high-performance computing event.

The conference will take place in person at the America’s Center, as well as virtually through a limited digital program. SC25 offers NCCS staff and students the opportunity to share their work and expertise with the HPC community while learning about the latest technologies and accomplishments from the world’s leading vendors, research organizations, and universities. The theme of this year’s conference is ‘HPC Ignites.’
