Big science user requirements I

This session will discuss the network capacity requirements of big science users and how these requirements are evolving as scientific research becomes increasingly data-intensive.

• 09_HL-LHC dataflows: An experiment view - Mario Lassnig (CERN)'25

The LHC experiments are facing a ten-fold increase in throughput requirements for the High-Luminosity upgrade. In addition, the
complexity of dataflows is ever evolving, pushing the boundaries of our infrastructure. In this talk, we highlight important use cases shared by the LHC experiments, and delve deeper into the specific needs of the ATLAS Experiment.

• 10_Computing Models for Processing Streaming Data from DOE Science - Graham Heyes (Jefferson Lab) '25

Graham Heyes is the head of the Scientific Computing Department at Jefferson Lab. He was also the lead of the laboratory’s Data Acquisition Support Group. His current research interest is streaming data acquisition and analysis. This talk will explore what that is, and computing models, both hardware and software, that are appropriate for streaming data.

  Accelerate Science -  Chin Guok (ESnet) '25

DOE ASCR has been championing the Integrate Research Infrastructure initiative, which is to enable highly coordinated, collaborative research and integrating capabilities across DOE’s
world-leading facilities.  This initiative has the potential to drive DOE's funding and direction in the next decade.

Mapping big science requirements to what the R&E Networks are doing

This session will include presentations on the requirements of big science users and how these requirements can be mapped to the services and infrastructure provided by research and education (R&E) networks
