Build, Release, Testing

  • Feature Freeze
    • Test running (25-30), merging in related changes.
    • Some changes lost due to merge process.
  • Discuss policy on where to commit changes going forwards
    • Slushy Freeze
  • 4.3.1 State:
    • OSX - Tests are running
    • In testing
  • Users Test Meeting tomorrow


  • Technical Forums:
    • Kumar: Dealing with CASA Core and overriding in Code
    • George: Integration with VI and stacking
  • Relocatable build


  • Starting of 4.5 Planning process


  • EVLA pipeline release testing, CASA setjy issues resolved
  • ALMA pipeline release testing, possible gainfield=nearest problem, integration with wvrgcal and possible restore issues
  • ALMA pipeline HPC / MMS testing at ESO, works, memory issues in applycal, timing issues in plotms
  • ALMA pipeline lazy filler testing, works, times similar to those without lazy filler, to be used in combination with partition
  • ALMA pipeline testing of image analysis tools / new statistics framework, works well, somewhat mixed results on timings
  • work on web log support for multiple observing sessions
  • experiments on wrapping tclean
  • pipeline software deployment and configuration issues



  • Next Meeting 14:00 UT

Developer Reports

Monday Meeting
  • Sanjay Bhatnagar
  • Sandra Castro
    • Implemented a change in importasdm to not overwrite the online flags file if it exist. I also added the same behaviour to the second MS (wvr option) if it exist. (CAS-6805)
    • Implemented a change to LogOrigin so that it prints the MPI rank of each server when CASA is running in parallel, using MPI. (CAS-6705)
    • Created a quick-guide for the developers on how to run CASA's functional tests using Multi-MSs. The document is available in the svn repository: gcwrap/python/scripts/mpi4casa/CASA-4.3-Multi-MS-Structure-doc.pdf. (CAS-7299)
    • Tested the ALMA pipeline with Multi-MSs.
    • Gave input to Dave on the implementation of msmd.summary(). (CAS-5053)
    • Verfying at the moment a problem in split using a concatenated MS with 12 and 7 m antennas. (CAS-7297)
  • Lindsey Davis
    • pipeline release management and testing
    • pipeline lazy filler support and testing
    • drafted document outline ALMA pipeline configuration and deployment issues
    • pipeline, HPC, SSA coordinate meetings
  • Joe Depa
    • Final version of flow chart, on the release.
  • Pam Ford
    • Implemented OTF calibration using a calibration library record in plotms; not committed in svn due to personal leave and further development/testing of CalibratingVI and MSTransformManager by George and Just
  • Kumar Golap
    • Added a new feature to retune data selection in SynthesisImager so that the data really selected spectrally is the intersection of image definition and the user data selection
    • Added a new tool to do linear masoning
  • Justo Gonzalez Villalba (last 3 weeks)
    • Completed MPIInterface for imaging parallelization / support for migration of tclean to MPI
    • Minor fixes in balanced partition mode to support multiple polarization setups per spw
    • Investigated and fixed performance issues reported by Pam in MSTransformIterator
    • Added possibility to time average across fields in mstransform as requested for plotms
    • Ported phase shifting code from the old VisBuffer framework to MSTransformBuffer as requested for plotms
    • Implemented a workaround in mpi4casa to have separated logfiles for the client and each server
    • Implemented a new LogFilter to filter out undesired exceptions in the server side like null selections.
    • Fixed scalabitity-related timeout issues in mpi4casa
    • Run scalability tests oriented to tests robustness under load conditions in mpi4casa
  • Jim Jacobs
  • Jeff Kern
    • Survey and Newsletter
  • Susan Loveland
    • CARTA
      • Bug fixes for demo
      • Histogram
    • Viewer: Investigated user question about statistics beam area with Dave's help
  • David Mehringer
    • Completed stats framework implementation
    • Completed multi-key scan definition for CAS-7353.
    • Was unable to complete CAS-5053 (msmd.summary() method) before feature freeze because I was unaware that the commit moratorium due to the casacore merge was going to take place and the changes others were simultaneously making to MSMetaData, so did not plan for these delays.
    • Fixed CAS-7330 (ia.collapse() performance issues.
    • Fixed (CAS-7363) impbcor fails when using exported and "re"-imported image
    • Resolved double delete segfault introduced in LatticeStatistics after casacore merge.
    • Communicated with Kana and Darrell re: their and my simultaneous changes to MSMetaData.
    • Communicated with Nathan and Susan re: calculating beam area in pixels.
  • George Moellenbrock (~2.5 weeks)
    • CAS-7285: CalibratingVi2. VisibilityIteratorImpl2 plumbing complete; hookup to calibration nearly done. Discussions with Justo re related MSTransformManager adjustments, which turn out to be minimal.
    • Consulting with Pam on various plotms developments, including OTF calibration via CalibratingVi2 (demonstrated all of the plumhing last week).
    • Wrote CASA newsletter article on Vis Weights.
    • Some advising with Rosita on ALMA poln CASAguide
  • Dirk Petry
    • working on wvrgcal and ephemerides related tickets
    • fitsidi will probably have to wait for CASA 4.5
  • Urvashi Rao
  • Darrell Schiebel
  • Julian Taylor
  • Takahiro Tsutsumi
    • Looked at the prerelease 4.3.1 failure on makemask unit test - mismatch between the test and data repo (data is too recent)
    • Fixed tclean so that it will not to cause a seg. fault when datacolumn specified is non-existent
    • Investigated CAS-7362 (tclean does not work for stokes='Q','U',or' V')
    • Fixed a setjy bug on model image handling for a spw with a single channel
Friday NAOJ Meeting
  • Kanako Sugimoto
    • communication with Mark about future contribution to B&T
    • Bunyo is collecting development request for CASA 4.5 (Due: March 13)

    • Update of ATM library ( CAS-7220): Dominique would finish update until March 4th.
    • setting image beam size by sdimaging ( CAS-5488): I think it's done. waiting for Darrell to re-activate commit to casacore.
    • MS transition: support of per spectrum baseline fitting parameter in tsdbaseline ( CAS-7003): investigated interface definition. started planning and discussion.
  • Wataru Kawasaki
  • Masaya Kuniyoshi
    • implemented calmode=‘apply’ in tsdcal. [CAS-6995]
    • verifying that it works correctly (unit tests), e.g., corrected data = data x FPARAM. [CAS-6995]
    • asking George about WEIGHT, WEIGHT_SPECTRUM, and some applymode-related things. [CAS-6995]
  • Takeshi Nakazato: Almost finished CAS-6993, set status to RTT
