Build, Release

Verification Testing

Validation Testing

Architecture

HPC

  • ALMA Pipeline parallel testing
    • Resumed testing on other datasets. Have added 3 datasets running automatically in ESO's Jenkins. We are having trouble catching failures from the pipeline. It exits with status 0, which Jenkins catches as a success. For example, the failure inside tclean due to the VI/VB2 minMax() isn't rethrown and is never caught later no matter how we try.
    • Have made experiments with cpu pinning (to use only one socket); the gain is very small in some cases. Need to experiment further....
    • Tried to verify the fix for CAS-9604: PyParallelCubeSynthesisImager instance has no attribute 'pbcorImages', but the pipeline needs to be modified first as now the node files end up in another directory.
  • EVLA Pipeline parallel testing
    • Long_runs dataset: it stopped inside stage 6 (applycal). I think it run out of memory on casa-dev-09. This machine has only 8Gb RAM. Will verify it in lustre nodes.

Development

Pipeline

  • CASA 5.0 testing
    • tclean frequency selection VI/VB2 bug fixed, pipeline adding support for new tclean HPC fle handling
    • mixed success with gaincal / bandpass / gencal VI/VB2 testing
      • bandpass does not accept solint in frequency units, should be fixed but
      • segfault from gaincal in 5.0.0-155 tarball
  • Development
    • Progress on image refactor for VLASS imaging support
    • Progress on first VLA reprocessing use case, ASDM -> MS with optional flagging, data selection, and smoothing

Developer Reports

Monday Meeting
  • Sanjay Bhatnagar
  • Sandra Castro
    • More Plone documentation revision and follow-up.
    • Setup casa-dev-09 and 10 to run the CASA trunk in Socorro. Where is the CASA DATA repository located?
  • Lindsey Davis
    • Worked on EVLA ASDM->MS reprocessing use case
    • Followup on imaging issues
    • CASA 5.0 testing
  • Pam Ford
  • Enrique Garcia
    • Fix CAS-9864. mstransform fails if there is channel averaging and spw combination. Fixed but the whole mstransform guessing of compatible inputs is messy and error prone. Most of it should be gone when moving the whole mstransform to TVIs.
    • Create jobs in ESO Jenkins to test off git rather than svn.
    • Created report for the comparison of uvcontsub/uvcontsub3/msttransform (CAS-5174). Reviewing it carefully with Justo. Bottom line: the differences reported by Jennifer are expected.
    • Reformat TVI guide in Plone (CAS-9906).
  • Bob Garwood
  • Kumar Golap
  • Jeff Kern
  • David Mehringer
  • George Moellenbrock
  • Dirk Petry
  • Martin Pokorny
  • Federico M Pouzols
    • Quick "fix" for issue in mstransform pre-averaging + regridding ( CAS-9798) in 4.7.2
    • Following plans and tests around tclean ( CAS-9852) and cvel ( CAS-9241) + mstransform ( CAS-9798)
    • Clarification and verification of CAS-9077 with Urvashi (mpi4casa mpi commands, return values and advanced use)
    • Looking into issues in parameter initialization & defaults in parallel tasks ( CAS-9871)
    • Testing performance/resource requirements of ALMA pipeline in parallel ( CAS-9519)
  • Urvashi Rao
  • Darrell Schiebel
    • mirroring and verification of git data repository
  • Ville Suoranta
  • Takahiro Tsutsumi
    • Fixed a bug in tclean's start/width
    • Investigated the pruning issue reported by Claire
Friday NAOJ Meeting
  • Kanako Sugimoto
  • Wataru Kawasaki
  • Masaya Kuniyoshi
  • Takeshi Nakazato
  • Renaud Miel
