News / Meetings / Visitors

  • Kelly Sharp in town this week to work on Plone migration.

Build, Release

  • synced to Subversion. Casacore and Asap commit references are being updated automatically for now
  • CI builds run from the Git clone with Bamboo ( NRAO people should be receiving emails on build failures, requested the rest of the developers to be added as well.
  • CI builds are run on EL6, EL7 and OS X. CI build will try a fresh build if the update doesn't work. Hence it can take up to couple of hours to get an error message
  • Upgrading to RedHat Developer Toolset 4.* at the beginning of the next development cycle is a reasonable option because both RHEL6 and RHEL7 are supported.
  • RHEL6 build failed due to ASAP checkout
    A    casa-test-4.7.73/asap/external-alma/atnf/PKSIO/NROFITSDataset.h

  • RHEL7 build failed due to casacore checkout
    Fetching external item into 'casa-test-4.7.74/casacore':
    svn: warning: W175002: Server sent unexpected return value (504 Gateway Timeout)
    in response to REPORT request for '/casacore/casacore/!svn/vcc/default'
    Checked out revision 37301.

Verification Testing

  • Rolling up pipeline with the stable tarball
    • Already happening on dmg
    • runsetup incompatibility
    • If you were to test older versions of the tarball, there could be inconsistent results from pipeline version differences between pipeline trunk at the time of the tarball and current pipeline trunk
    • Technically feasible, but only decision that needs to be made is which version of pipeline to be rolled up with
    • How about grabbing the pipeline trunk for the stable tarball?

Validation Testing





  • C4R2 development and testing, calibration, imaging, web log
  • CASA 4.7 / C4R2 issues
    • pipeline domain object / msmd efficiency, ongoing improvements from Brian and David
    • calibrator solve and apply behavior for gaincal combine='spw' interp='linearPD' tables
    • tclean performance and optimal setting for chanchunks
    • plotms iterator / averaging bugs
    • auto-boxing


Developer Reports

Monday Meeting
  • Sanjay Bhatnagar
    • Vi/VB2 migration in tclean, outstanding item is writing to Virtual Model column.
  • Sandra Castro
  • Lindsey Davis
    • updated gaincal combine=' spw' heuristics for C4R2
    • tracked down gaincal combine='spw' solve / apply issue that impacts calibrator imaging, sent results to George
    • end to end testing with CASA 4.7
    • restoring beam definition discussions with Amanda, David
    • pipeline / AQUA interface discussions with Jeff
    • started restoring ACS development environment on RHEL6
  • Pam Ford
    • ADMIT (ALMA Data Mining Toolkit) for most of the week: met with UMD developer, admit source tree, casa+admit install, developing for nightly regressions at NRAO
    • Calibration: attended calibration talk at Synthesis Imaging Workshop, talked with George and Juergen about cal tables for plotcal migration to plotms
  • Kumar Golap
    • Summer School
    • EVLA OTFI and pointing table
  • Justo Gonz├ílez Villalba
    • Work in progress with uvcontsub and spw combination TVIs.
  • Jim Jacobs
    • Fixed regression caused by cloning scratch columns. Cloning was failing when the original column was managed by the lazy filler.
    • Explored problem where column keywords are ignored when creating a new column (cas-8724). Appears to be related to a big CasaCore mod that went in around the start of April. Pointed Ger at it to see if he concurs.
  • Jeff Kern
    • Job Posting for CASA Liaison
    • ADMIT Visit
  • Susan Loveland
    • Synthesis Imaging Workshop
    • CARTA
      • Reviewed first draft of Pavol's region model
      • Some work on context & zoom views in CARTA
  • David Mehringer
    • (CAS-8716) imstat slow on stacked images. Spoke with Ger who suggested aipsrc variable, but I pointed out that tmpClose was already being set in the image by tclean. He seems to agree then that overriding this configuration with yet another configuration variable is not the way to go. He suggested tclean set tmpClose=False. Not knowing what else do, since this really seems to be a decision that tclearn is making, I will escalate the ticket to Jeff.
    • (CAS-8729) create msmd.scansforfields. WIP. Submitted PR which was merged this morning (thanks Julian). Will finish up by committing gcwrap code today.
    • (CAS-8731) create msmd.scansforspws. RTT. Implemented.
    • (CAS-8627) beam PA listed in image summary is 180deg from what's listed in header. WIP. Much discussion about apps setting and reporting beam PAs in second vs fourth quadrant. There seems to be unhappiness with imaging apps setting beam PAs in second quadrant rather than the fourth.
      • In general when calculating Beam PA please put them in the first or fourth quadrant: Conventions page, to be created.
    • (CAS-8736) FITS related logger message priority change: Resolved. Implemented
    • (CAS-8717) exportfits slow on stacked images (from parallel clean): I assumed ownership, but given that this is the same issue as CAS-8716, I will escalate to Jeff.
    • (CAS-8725) imhead(mode='put') should write history to image: WIP.
    • (CAS-6907) multisource description in exportuvfits documentation is ambiguous: RTT. Updated documentation as requested.
    • (CAS-8715) imsubimage 'output file exists' message improvment: RTT. Updated message as requested.
  • George Moellenbrock
    • Summer School
    • Calibration VI2
    • Worked with Jive on VLBI in CASA
  • Dirk Petry
    • Support in the VPManager and Tool, retrieve a set of beams.
  • Martin Pokorny
    • Continuing IO performance testing: disentangling system file cache, disk access, and Table tile sizes.
  • Urvashi Rao
    • Started work on getting 'makepb' into the refactored imager (first target : what the alma pipeline needs)
  • Darrell Schiebel
    • Understand C++ and Structure101 configuration work
    • Exploring OSX startup issues (Tcl/Tk distribution/system conflict)
    • test install and update wcslib to version 5.15 on RHEL6
    • fixed startup issues on RHEL7 for CASA installed with RPM
    • started Scala course on Coursera
    • produced casacore example of wcslib 5.15 problems with tAWPFTM unit test run with existing cache
  • Ville Suoranta
    • Git/Bamboo build
    • Worked on Carta build & packaging issues
    • Investigated documentation generation for Pipeline
  • Julian Taylor
    • fixed qt gui of agentflagger with qwt6, patch sent for review
    • ran some tclean benchmarks with different settings, results summary coming soon
  • Takahiro Tsutsumi
    • Found and fixed a bug in imagename incrementation when restart=F in tclean
    • Continued looking at some of the issues in Juergen's report for parallel cube tclean. I did not find rerunning tclean (with restart=F) gives the different results for serial and parallel as Juergen commented on CAS-8582 (when tested with the same vla data with the parameter sets).
Friday NAOJ Meeting
  • Kanako Sugimoto
    • Invesitigation of the failures of google tests only on OSX
      • LineFinder _GTest: different manifestation of randomu number sequence in Linux and OSX: fixed
      • LineFindingUtils _GTest: only fails by make target. The test never fails if executable is directly invoked. strange behavior of ctest + google test? ... invesigating with Jim
    • Started to work on MS transition of sideband separation
  • Wataru Kawasaki
  • Masaya Kuniyoshi
  • Takeshi Nakazato
