    Developer's meeting

    more detailed report on trigger matching (Enrico, Roland):

    • setup used:
      • used native artdaq trigger matching facility
      • frame-based fragments
      • FELIX BoardReader (and other artdaq programs) running on a different PC than the FELIX host (which is not sufficiently powerful to accommodate all programs)
      • generating periodic triggers running in a separate trigger BoardReader
      • did not use the timestamp generated by the emulator for now, as there is no synchronisation between the emulator and the trigger BoardReader
    • next steps:
      • do away with the "cheating" on the timestamp
      • move the system to the actual FELIX PC, so as to allow to run the FELIX BoardReader and the rest of the FELIX system on one and the same machine
      • work on trigger-matched fragment
    • but the schedule is also affected by ongoing WIB activities (these take precedence, due to availability of both h/w and experts)

    data overlays class(es):

    • immediate concern: Antonino would like code for the frame-based FELIX fragments
      • based on Milo's code, but correctness to be verified; code also to be entered in the official gitlab repository (Roland in discussion)
    • will move to more advanced overlay as compression implementation progresses
    • Eric & Roland: in favour of a scheme in which the data type mostly distinguishes between FELIX and RCE, and fragment metadata information is used to determine further details

    google doc (Frank):

    • would be good for all to think about structure, and hopefully contribute
    • Eric: would this document also useful for the DUNE consortium formation? Frank: not obviously so

    discussion with MicroBooNE about use of their data/MC (Frank, Eric):

    • discussed our intended use of their data/MC with them last Friday
      • idea was to cast this into an MoU, detailing number of events (< 100) and usage details (no physics studies, no results obtained using these data to be made public)
      • not completely a done deal at this point (concern by one person about a potential clash of interests, related to work on a SNB trigger)
    • Roland: about to finish a report on compression using Quick Assist. This contains some results obtained using these data -- can these results be made public? Eric: best to hold off for now

    Next meeting: tentatively on August 23.
