Topics for discussion:

  • Gen 3 conversion (

    ):
  • Precursor processing (Meredith Rawls ):
    • working on lists of visits for HSC, hopes to kick off processing tomorrow
    • will make ticket for April DECam rerun
  • report from NCSA (Unknown User (emorganson) et al):
    • out today
  • ap_association/SDM/fakes/alerts (Unknown User (cmorrison)):
    • focusing on unit tests for fake analysis pipeline
  • DCR (Ian Sullivan ):
    • slowed last week by problems with nublado
    • sent DCR diffim to gen3 ticket to Gabor, seems to be working
    • now back to cleaning up Algorithms Workshop notebooks
  • Image differencing (Unknown User (gkovacs) ):
    • working cleaning up tests of decorrelation afterburner; some existing tests but Gabor thinks they need to be more extensive (since they obviously didn't catch DFT errors)–existing test passed basically because exact Gaussian PSF case is a special case.  Hopes to have a PR in today or tomorrow
    • will reorganize tickets slightly
  • Review CI (https://chronograf-demo.lsst.codes/):
    • nothing new this week.  We talked some about the change in the ratio of DIASources/direct image sources from last week; Krzysztof put a couple of culprits in last week's notes
      • this change maybe most likely? https://github.com/lsst/obs_decam/commit/df313b171becdad1662349540b5cebc87c74cd17
      • John S: trivial to revert the change and see if the numbers go back to where they were
        • no volunteers to do it; John S may try if he has a moment
      • John P asserts that he thinks the new behavior (convert ints to floats) is correct.  It's necessary to work in Gen 3 in any case.  There is apparently inconsistency in what types get produced in gen 2 and 3
      • John S is worried that this got merged without any knowledge that it caused a change in performance.  Do we need to be reviewing changes in this meeting before merging? 
      • John P: it's easy to fire off a ci_hsc job in Jenkins, doesn't even know what he would do here
      • Eric: can we fire off AP CI jobs like that?
      • Krzysztof: you can do it on a tag, but not a ticket branch.  Would need a Jenkins guru to  change that, plus a Chronograph guru to avoid sending ticket-branch metrics into the dashboard as a whole
      • discussion of what numbers are important.  John P: why do so many jump around?  Chris: execution order isn't fixed.  Should be easier in Gen 3–sounds like we should make  DM-12549 - Getting issue details... STATUS a priority so the DIAObject metrics are easier to reason about.  Sound be possible when Krzysztof finishes the Gen 3 CI system.  Eric thinks when we have fakes in we will also have some very useful new metrics to monitor
      • Chris M: ratio of DIASources/direct sources doesn't depend on execution order
  • AOB
    • none
