News / Meetings / Visitors

  • Pipeline F2F: Tokyo, 5/7 - 5/11
  • NRAO Users Committee Meeting: Socorro, 5/14 - 5/16
  • CASA Newsletter, 5/9
  • Obs mode 7 in Chile



  • Pipeline ALMA and VLAA science target development (non HPC related, 5.3 related) is actively proceeding on the pipeline trunk. This must be kept in mind when planning automated target testing campaigns, e.g. HPC campaigns. See CAS-11307, CAS-11308 which were found by developers and validation testers, but may take some time to fix.
  • Lots of pipeline tasks generate warnings and error messages. Tickets should not be opened based on warnings and errors alone.
  • Subtle numerical changes in CASA calibration code caused pipeline test to fail. Test numbers need to be fixed


  • Pipeline+CASA issues - not specific to parallel
    • Current status with 5.3-prereleases: about half of the test datasets fail for various reasons.
    • Critical need for automated testing!
    • New issues last week:
      • CAS-11308 "Error in task hifa_imageprecheck: invalid literal for int() with base 10: '5,7,9,11'" - fixed
      • CAS-11307 "exportfits fails at the end of the ALMA pipeline: Value of keyword SPW will be truncated at 68 characters".
  • CAS-11322 "Blockers for parallel use of ALMA pipeline".
  • CAS-11320"Differences in serial and parallel pipeline runs for CASA 5.2 testing"
    • Mask issue ( CAS-11323)- could it be related to 1st point of CAS-11322? There was already CAS-10857.
    • Phantom SPWs issue: see recent discussion in CAS-7341.
    • CAS-11321 Warnings like "hif_makeimages Warning Check source fit for J0909+0200 spwd 17: offet 31.368marcsec 0.061beams fit flux 0.041Jy decoherence 27.925 percent" - where does this come from?

Developer Reports

Monday Meeting
  • Sanjay Bhatnagar
  • Sandra Castro
  • Lindsey Davis
    • per ASDM check source imaging prototyping with Dirk
    • Followup on MS / MMS restoredata issue, the chosen way forward dependsPWG decisions
    • Obsmode 7 discussions with Kana
  • Bjorn Emonts
  • Pam Ford
    • 5.3 plotms fixes: showatm/tsky hang (CAS-11292) complete; premature error that it failed to start (CAS-11310) ready to validate
    • 5.4 plotms design doc in progress
  • Enrique Garcia
  • Bob Garwood
  • Kumar Golap
  • David Mehringer
  • George Moellenbrock
  • Dirk Petry
  • Martin Pokorny
  • Federico M Pouzols
    • CAS-9231 "tclean should not include TELESCOP and OBJECT in the miscinfo keyword in output images" - fixed
    • CAS-10664 "Object name not in header for most images from tclean with mtmfs enabled" - fixing
    • Testing / following on:
      • Various test runs of the ALMA pipeline in serial and parallel mode
      • CAS-11310 "plotms relaunches itself when already running" - validating, looks goo.
      • CAS-10392 "Python MemoryError: tclean respects memory limits but pipeline code is more memory hungry?" - validating, fixed in new findContinuum
      • CAS-10768 "Resource Predictor for Imager" - following on validation and updates.
      • CAS-11269 "mstransform should not create WEIGHT/SIGMA_SPECTRUM in output MS if they're not available from the input MS and usewtspectrum=False".
      • CAS-10937 "MPI CASA: tclean creates new directory and does not parse the dirname correctly" - fixed and merged.
  • Urvashi Rao
  • Darrell Schiebel
  • Kanako Sugimoto
  • Ville Suoranta
  • Takahiro Tsutsumi
Friday NAOJ Meeting
  • Wataru Kawasaki
  • Takeshi Nakazato
    • CASR tickets created: CASR-293, CASR-294, CASR-295
    • CAS-11041 Plone document for sdsidebandsplit: asked Jen to validate the contents
    • CAS-2961 pseudoI imaging: tsdimaging seems to work fine. create new test package and ask Jen/Anish to test the task again.
    • BUG REPORT: CAS-11306 plotms problem found by Akira (Blocker)
  • Renaud Miel
    • CAS-8087 PlotMS pointings: creating small testcase data for verification & unit tests
      • selection of a subset of circles from a double-circle scan pattern: circles whose center are best aligned with a specified regular polygon
      • next step is to perform the final selection on the original MS using the time ranges defining the circles
        • that is: keep only data for which the pointing direction interpolated at MAIN timestamps and converted to J2000 belongs to the specified circles
    • Intel Parallel Studio 2018 Update2
        • investigated issue: by default Vtune amplifier fails to attach to CASA
        • solution: $ AMPLXE_RUNTOOL_OPTIONS=--no-altstack amplxe-gui &
