In October 2022, ESnet’s Science Engagement Group convened and hosted ESnet’s first Science User conference to foster cross-interactions between DOE research scientists, users, network engineers, and stakeholders. The focus was different from the longtime ESnet Site Coordinators Committee (ESCC) meeting, a technical forum that brings together IT representatives from the ESnet-connected sites. Held in Berkeley, California, in conjunction with the unveiling of ESnet6, Confab22 sought to showcase how scientists across domains use ESnet6 and its advanced services effectively and to provide a platform for bidirectional conversations, particularly across siloed application and IT communities.

The technical program enabled discussions among the 100-plus attendees about co design activities including:

• ESnet6 capabilities in development and science user thoughts, with ESnet leadership
• Exascale biology compute needs and network uses, with Dan Jacobson of Oak Ridge National Laboratory
• ARIES project (see page 33) and future “superlab” network uses, with Rob Hovsapian of National Renewable Energy Laboratory

• Field Science and Wireless/5G use cases, with ESnet staff
• DOE Integrated Research Infrastructure initiative with ASCR Facilities Director Ben Brown
• Derecho simulation and data visualization with Paul Ullrich, U.C. Davis, and Brad Carvey, Sandia National Laboratory.

The discussions started at Confab have resulted in several new collaborations between ESnet’s Science Engagement group and external stakeholders. The conference will now become a regular ESnet activity driving outreach and user support efforts.

SC

Each year, ESnet participates in the International Conference for High Performance Computing, Networking, Storage, and Analysis, known simply as SC, one of the largest high performance computing conferences in the world, with an emphasis on dataintensive scientific support. The contributions can be divided into two main categories: First, ESnet offers connectivity and services to the conference, facilitating live demonstrations and tests. Second, ESnet staff members actively participate as essential volunteer team members responsible for constructing SCinet — an annual conference network and the “world’s fastest network” for the duration of the conference. This network serves as a testbed for innovative problem-solving strategies tailored to address challenges within the HPC community

ESCC

Each year, ESnet convenes the ESnet Site Coordinator Committee to share insights and guide the future of the ESnet infrastructure. In 2022, the group, made up of technical representatives from ESnet’s supported sites, met in person for the first time since 2019 to collaborate on operational, network engineering, and security innovations and challenges.

OFC

ESnet participates in talks and demonstrations for OFC, the Optical Fiber Communication Conference and Exhibition sponsored by Optica, IEEE Communication Society, and IEEE Photonics Society, as well as in building OFCnet, an unconventional high-speed network connecting the show floor to a research center in Chicago.

TNC

The largest R&E networking conference, TNC is co-funded by the European Union via the GÉANT (GN4-3) Project. It attracts more than 800 participants from 70+ countries, representing national and regional research and education networks, schools and universities, technology providers, and scientific projects.

Internet2 Technology Exchange

Hosted by Internet2, a community providing a secure high-speed network, Cloud solutions, research support, and services tailored for research and education, the TechX conference brings together the global R&E community.

The Quilt Annual Meeting

The Quilt is a national coalition of non-profit U.S. regional R&E networks representing 43 networks across the country. Members of The Quilt provide advanced network services and applications to 900-plus universities and thousands of other educational and community anchor institutions.

ACM SIGCOMM

ACM SIGCOMM is the flagship annual conference of the ACM Special Interest Group on Data Communication, an important conference in networking held in Amsterdam in 2022. ESnet staff co-authored the invited paper “Transport Control Networking: Optimizing Efficiency and Control of Data Transport for Data-Intensive Networks” and gave a keynote.

In 2022, ESnet staff delivered 57 technical presentations, published two dozen conference papers and journal articles, and filed one patent. (For a full list, with links where available, visit es.net/publications2022.)
