Agenda:

  • Announcements
  • ERSAP/RTDP UI
    • RTDP ontology language based on RDFS, used for the serialization, communication, and archiving of configuration data.
    • Continuing development of the UI.
  • Large-scale Deployment and Scaling Test of the CLAS12 Data-Stream Processing Application at NERSC through EJFAT LB at ESnet
    • Impossible to sustain processing for more than 15-20 minutes.
    • Insufficient conditions to test the return path
    • JIRIAF successful operations
    • Challenges encountered in requesting additional resources due to the resource limits set for the EJFAT project.
  • Developing a Demo for a Full Streaming Pipeline:
    • Developed and demoed for a full streaming pipeline, starting from streaming readout of the FADC250 through the VTP, passing VTP aggregated time windows to CODA PAGG (primary aggregator) to ER. The ERSAP data-processing pipeline interface to the ER ET system, identifying FADC hits, applying a simple trigger algorithm, and visualizing triggered data in real time.
    • Request to update EMU to be able to accept multiple output channels with user-programmable prescale factors for two output channels, one critical channel that outputs all the stream events, while the second output channel outputs some percentage of the stream simultaneously.
      • The current mechanism of the EMU provides multiple output channels, where each channel gets a stream unit in a round-robin fashion. Seeking an elegant solution to avoid the stream unit copying required by the previous request.
  • RTDP report
  • Updates on the EJFAT project
  • Preparations for the CHEP24 conference.
  • AOT
