Agenda:
- Announcements
- Preparing talk on Confab
- Streaming CODA with EJFAT-based Event Building
- Current Status of EJFAT Integration with CODA Streaming infrastructure
- Ongoing efforts to integrate the EJFAT high-performance transport and adaptive load-balancing framework into the streaming CODA infrastructure.
- Installed the required software stack on tania.jlab.org, including:
- e2sar, e2sar-java, ersap-java, ersap-cpp, ersap-e2sar, coda-3.10_devel
- Dependencies: protobuf, gRPC, ZeroMQ, and others.
- Successfully validated ersap-e2sar test pipelines on tania.jlab.org.
- Issue: tania.jlab.org experiences occasional system freezes.
- Installed the required software stack on tania.jlab.org, including:
- Next steps:
- Validate ersap-e2sar test pipelines on ejfat-6.jlab.org.
- Continue installing the required software stack on ejfat-6.
- Plan to integrate e2sar reassembler within the CLAS12 data-stream processing pipeline.
- Ready to stream VTP data into the CODA-ERSAP pipeline, where the CODA aggregator is represented as an ERSAP actor.
- Ongoing efforts to integrate the EJFAT high-performance transport and adaptive load-balancing framework into the streaming CODA infrastructure.
- Current Status of EJFAT Integration with CODA Streaming infrastructure
- RTDP
- Extracting and processing VTP payloads from PCAP files recorded during recent beam studies, as part of the RTDP project.
- Broadcasting PCAP-based VTP streams to TCP sockets (Completed by Jeng).
- Development of an ERSAP actor capable of receiving these VTP streams and preparing the data for downstream processing (Jeng, Vardan).
- Extracting and processing VTP payloads from PCAP files recorded during recent beam studies, as part of the RTDP project.
- PET Data Acquisition and Processing Workflows
- Ongoing Integration of PET Detector Streams into the ERSAP Ecosystem
- Continuing work on integrating PET detector data streams, including stream acceptance and processing within the ERSAP framework (John, Vardan).
- Current Issue: Configuration of ERSAP DPE host IP and user experience (UX) challenges.
- Ongoing Integration of PET Detector Streams into the ERSAP Ecosystem
- Streaming CODA
- Required Upgrades for AFECS
- EJFAT Integration: Extend AFECS to support EJFAT as an additional high-performance transport framework, alongside Socket, ET, and cMsg. This will enable adaptive data movement, dynamic load balancing, and optimized event distribution within the CODA ecosystem.
- JcEdit Extension: Enhance JcEdit to support ERSAP actors, including RTDP components, along with their definition and configuration.
- Required Upgrades for AFECS
- AOT
