Development

5.3 High Level Status - https://open-confluence.nrao.edu/pages/viewpage.action?pageId=7046483

5.3 Dashboard - https://open-jira.nrao.edu/secure/Dashboard.jspa?selectPageId=11005

Pipeline

  • CASA 5.1 / Pipeline
    • Flagged central channel restoring beam computation fix implemented,. Under validation by Juergen.
  • CASA 5.2 / Pipeline
    • Restoring beam computation heuristics for cubes implemented and verified by pipeline group. Under verification by HPC group.
  • CASA 5.3 / Pipeline
    • CASA / Pipeline callibrary integration
      • Major issue is sub-selection handling, e.g different sub-selections wit different calibration paths
    • Current pipeline sensitivity estimates are precise but inefficient
      • A combination of recipe and heuristics changes should both simplify the code and make it faster
    • Cycle 6 ALMA "maximize sensitivity by using all available antennas" observing policy will seriously complicate IF imaging heuristics
    • Inefficiencies in update ms tool getdata method, possible vi/vb2 problem
    • Occasional and non-repeatable plotms failures in the VLA pipeline

HPC

Users

  • Feedback please:
    • CASA-flyer AAS (attached below): Highlights: 1). "Pipelines: a core aspect of CASA development"; 2). "tclean: the improved imaging task"; 3). "CASA Docs: the new documentation"; 4). "Parallelization: faster performance - Coming soon!"
    • CASA website revised: https://casa.nrao.edu/index_testcopy.shtml
  • List of known 'viewer' issues attached below -- problem that viewer has not been supported for years. Discuss (1) what can we do about it? (2) how to we communicate back to users?

Developer Reports

Monday Meeting
  • Sanjay Bhatnagar
  • Sandra Castro
  • Lindsey Davis
    • CASA / Pipeline callibrary integration discussions with George and Juergen
    • Pipeline sensitivity computation heuristics discussions with Crystal, Remy, and Dirk M.
    • Fixed a source / field selection bug in the check source QA heuristics
    • Updated ALMA IF applycal heuristics to use interp='nearest' instead of 'linear' for all applied calmode='a' solint='inf' gaincal tables
    • Discussed ALMA Archive efficiency / error handling issues with Alisdair Manning
    • Helped SSA group with ALMA pipeline issues, including identifying non-standard CASA and pipeline versions
    • Reviewed pipeline inputs handling changes and found a couple of bugs
  • Bjorn Emonts
  • Pam Ford
  • Enrique Garcia
  • Bob Garwood
    • CAS-10386. New ASDM tables added to CASA. This is awaiting validation.
    • CAS-6832. Filler should fill until the first bad scan is encountered. The fix for this is now understood. Implementation will wait until higher priority items have been dealt with. * CAS-10949. Filler behavior when missing binary files are encountered. I think the discussion has died down and I'll try and get consensus on the appropriate fix this week. * CAS-10683. Remove boost dependency from the filler. I've added an ICT ticket on the ALMA side so that I can start this work. It's low priority but it does require ALMA approval and so this work will happen when that approval happens.
  • Kumar Golap
  • David Mehringer
  • George Moellenbrock
  • Dirk Petry
  • Martin Pokorny
    • Profiling async vii2 implementation
  • Federico M Pouzols
    • Testing various issues for CASA 5.2
    • Fix for CAS-10795 for CASA 5.2
    • Re-runs of the pipeline in parallel mode
  • Urvashi Rao
  • Darrell Schiebel
  • Ville Suoranta
  • Takahiro Tsutsumi
Friday NAOJ Meeting
  • Kanako Sugimoto
    • developiong a new sideband separation task, sdsidebansplit ( CAS-8091)
  • Wataru Kawasaki
    • CAS-7514
      • modified wrong storage option strings in casacore/tables/Tables/StorageOption.h, then created a pull request
      • writing a report on how many file descriptors are consumed when sdimaging runs
    • sent an abstract of an oral presentation in the next ASJ meeting on our recent development for CASA single-dish part
  • Takeshi Nakazato
    • completed CAS-10935
      • while issuing pull request, listcal_regression was failed in the first test but it was successful in the second attempt. I'm not sure whether it is originated by any temporal problem on testing environment or problem in the code itself (such as use of uninitialized memory area).
      • I also noticed that the build failed on my 10.12 development environment although Bamboo test server is working fine. It stopped when compiling some external code for crashreporter.
    • hand over of management work (from Kana)
  • Renaud Miel
    • CAS-8087 PlotMS Pointings
      • Tested VIVB2.direction1 with lissajous scanning pattern dataset, with ordered and not ordered pointing table Screenshot
      • Tested VIVB2.direction1 bug fix for CAS-10819 Screenshot
      • Tested VIVB2.direction1 with double-circle scanning pattern dataset, Screenshot
