Build, Release

  • XCode9 broke a number of MacPorts. Most critical ones were fixed early this week but 8.x.x is still the safer bet.
  • OSX10.11 end-of-life
  • 5.1.1 release schedule and branching? Which pipeline branch to use?
  • We have three releases planned for the next few months and have been in a perpetual release mode since 5.0. Is this the new norm and should we plan on monthly releases?

Verification Testing

      • Any further info on this?
      • Urvashi suggests this might need another feature specific to parallel flagdata's summary mode
        • We need to sync the dictionaries to provide one output one.
        • New JIRA ticket to cover this effort?
      • CAS-10202: Find a way to consolidate aggregate RFlag results in 'calculate' mode when running on MMS
        • related ticket for flagdat(mode='rflag')
        • Likely to be a legitimate difference between serial/parallel, and we should confirm, but maybe we can ignore it, or do an approximate combination of thresholds only for the 'rflag,calculate' mode. ( i.e. not critical for 5.2 )
  • Testing some ATCA Casaguides, which are close to being committed
  • CAS-10730: -m was not working
    • Akeem has fixed it, now assigned to Sandra for final testing
  • Work has started on unifying runUnit and runRegression scripts
    • Laying the groundwork for adding functionality

* Report about lustre performance.


  • CASA / pipeline 5.1
    • 1 pending ALMA patch, 2 pending VLA patches, waiting for ALMA end to end tests to complete before creating a new tarball
    • ALMA Cycle 5 data transmission and storage concerns
  • CASA / pipeline 5.2
    • image parameter handling patch ported to 5.2
    • don't worry too much about Cycle 2 project pipeline failures, Cycle 2 suffered from a lot of missing / incorrect meta data problems
    • separation of pipeline task, CASA task, CASA tool inefficiencies and impact on total serial vs HPC run times needs to be more clear to everyone
    • some reporting issues are due to serial vs HPC handling of output dictionaries, e.g flagdata, tclean, etc
  • CASA / pipeline 5.3
    • Cycle 6 refactoring and cleanup in progress, flagging, calibration, imaging, templates
    • Session support / HPC framework enhancements in progress
    • Cycle 6 science goals are modest, science ticket review almost complete,


  • CASA 5.2
    • flagdata summary mode for parallel runs may need an explicit merge (no ticket yet)
    • performance of imageanalysis tasks on reference concatenated cubes ( ideas still to be discussed )
    • need to analysis/understand observed differences in tclean speedups (legitimate or not)

  • CASA 5.3
    • Statwt2 requirements update : ongoing
    • Imaging team ironing out details/interactions for iteration control re-write, parallel cube changes, autoboxing connection with iteration control (+ plans to address other issues)
    • George : update on VLBI work from recent visit abroad ?
    • A couple of new bugs - phasecenter related error, tclean selection-related seg-fault(!)
    • Anything else ?

    • ms tool refactor/rename broke Sandra's pipeline test (CAS-10818) - fixed ms.selectinit() to issue warning and remove selection for invalid DDID. Back to Sandra for validation.
    • cal library parser (plotms callib param) bug causing syntax error for quoted strings within strings (CAS-10736) - fixed, pull request merged
    • investigating plotms spawning multiple windows (CAS-10822) - suspect dbus failure is causing it
  • Enrique Garcia

    • CAS-10738 : ephemeris code in the filler. The work on this is done. Just wrapping up the testing of the most recent tarball and will move it to "read to validate" later today.
    • CAS-10732 and CAS-10665 : investigating the speed (slow) of asdm2MS and bdflags2MS. I've just begin work on this. I plan to spend a week getting a sense of where things seems particular slow before tabling this work to move back to more specific filler bugs/features.
