Agenda:

  • Announcements
    • SC24 Demo Preparation: Finalizing elements for the upcoming SC24 demo.
  • Preparing a new data-stream processing test
    • Reassembly Engine: Integrating with Prometheus for enhanced metrics support.
    • TDP/DPUX as JIRIAF Front-End: Implementing the RTDP/DPUX framework at the JIRIAF front-end for testing.
    • EJFAT Testbed Commissioning: Commissioning the data-stream test on the EJFAT platform.
  • Streaming CODA
    • CODA control events
      • Discussion on communicating VTP/ROC configurations (run-type) to the Event Builders (EBs).
      • Strategies for informing EBs when all VTPs or ROCs have entered the prestarted state.
      • Mechanisms to notify CODA components about the end of a run.
    • Role of the load balancer (LB)
      • The LB simplifies CODA component discovery and networking.
      • Control event broadcasting via the Data Plane (DP) is not viable and of limited use.
      • CODA run-control (AFECS) platform as the manager for control events and the streaming DAQ state machine. CODA control events will be handled out-of-band for streaming workflows.
  • CODA AFECS platform
    • CODA platform and LB communication
      • Verifying or discovering the readiness of CODA "back-end" components.
      • Investigating the potential for accessing stream source data via the Control Plane (CP).
    • AFECS Pub-Sub servers for CODA-3.x
      • General discussion on cMsg and cMsg rc-domain servers.
      • Evaluating the feasibility of extending the LB CP as the sole pub-sub server for streaming CODA, potentially replacing cMsg with gRPC.
  • AOT
