News / Meetings / Visitors

• Paul Rosen Colloquium on the 22nd

Build, Release

• Linux is now using make app script
• Patches for 4.5.1
  • imregrid issue ready to move to 4.5.1
  • Filler issue is ok as well.

Verification Testing

• Starting to get some green boxes in the test-summary: https://svn.cv.nrao.edu/test-summary/
  • Thanks to everyone who got the tests in the green!
  • Last one failing on RH: pipeline test
• Discussed with Darrel and Ville about hardware needs for testing:
  • Additional OSX machines are needed
  • Replace warp with new hardware to run automated builds and smoke tests under RH 6 and RH 7

Validation Testing

Architecture

• Technical Forums:
• Crash Reporter is in progress, probably based on google breakpad.

HPC

• Work is in progress on several items: new separation axis in partition to support single-dish MMS; changes to mpi4casa; adapting alma-m100 regression to use tclean; changes in MMS structure
• We plan to have a telecon in 2 weeks.

Development

Pipeline

• CASA 4.5.1 / pipeline C3R4 released just before Christmas
  • setjy patch tested
  • tclean channel chunking patch tested
  • issues: imregrid memory usage, tclean table caching, image sensitivity calculation
• CASA 4.6 test tarball, repackaging causes import errors

AOB

Developer Reports

Monday Meeting

• Sanjay Bhatnagar
• Sandra Castro
  • Need input from Jeff and George on CAS-7890, the new baseline/antenna axis in partition to support single-dish MS.
  • The MMS structure needs a change. The subtables of the subMSs need to be symbolic links to the first subMS to avoid inconsistencies in the MMS if any sequential tool modifies a subtable later. But this is showing problems with setjy, which edits the SOURCE table even when usescratch=True. Task setjy only runs in parallel if usescratch=True, but even in this case, the Imager::open method tries to remove any OTF model in the SOURCE table. This causes a deadlock in some of the MPI Servers that open the MS. Work is in progress....
  • Discussions with Julian on the I/O Performance project implementation plan.
• Lindsey Davis
  • reviewed status of interferometry pipeline jira tickets
  • implemented support for simple calibrator source models (reference frequency, stokes parameters, spectral index) in interferometry tasks
  • cleaned up pipeline setjy task, implemented a more general setmodels task
  • discussed proposed frequency selection syntax changes with Sanjay (before Christmas)
  • discussed ms selection framework changes with Sanjay and Pam (before Christmas), pipeline use ms tool iterator
  • discussed calibrator model issues with George, specifically smodel parameter in bandpass and point source model setter in cb tool
• Pam Ford
  • CAS-7320 RTT- Support MS Selection by FEED
    • Created github account, pull request for MSFeedSelection branch
    • Parser uses flex/bison, selection string is a simplified form of antenna selection: [!]FEED[<OP>[FEED]] where FEED is a single INT (index), list, or range; and OP is '&', '&&' or '&&&' similar to cross/auto-correlation with antenna IDs
  • CAS-8231 - Add MS Feed selection to plotms - code ready to go when MS Feed selection added to NRAO casacore
  • CAS-8050: Remove obsolete MS selection frameworks (MSSelector) - in progress
    • This class is not only for selection but also for iteration and data I/O via Records
    • Used in low-level MSLister, MSSummary, MSRange, and MSFlagger (casacore); high-level MSContinuumSubtractor (code) and ms tool (gcwrap)
    • Need to discuss "Remove" with Jeff w.r.t backwards-compatibility discussion with Jim about changing code in casacore
  • Created personal git repo for casa code
• Kumar Golap
• Justo González Villalba
• Jim Jacobs
  • Cleanup of VI/ TVI
• Jeff Kern
  • Holiday past
• Susan Loveland
  • Stats plugin for CARTA, plugin for CASA regions.
  • UI issues with statistics
• David Mehringer
  • (CAS-8208) imregrid allocates more memory than available: RTT. Should now be fixed.
  • (CAS-8218) imstat Returns Intensity In Place Of Flux. Investigated. Not a bug as far as I can tell.
  • (CAS-8229) ia.pad() does not mask properly: RTT. Should now be fixed.
• George Moellenbrock
  • VI2 targets in Jira, working on Calibrating.
• Dirk Petry
  • Working with Michel on fix to lazy filler.
• Martin Pokorny
  • Visstat2 making progress, unit test in progress.
  • Changes in tClean, and questions about how to mix MPI and non-MPI builds.
• Urvashi Rao
• Darrell Schiebel
  • switched standard linux binary tar distribution to make-app
• Ville Suoranta
  • Time learning Bamboo and other tools.
• Julian Taylor
  • committed fix for CAS-7259, cvel2 flagging overlapping spw channels due to rounding error
• Takahiro Tsutsumi
  • Sick for a few days
  • Fixed a test_gencal failure, responded to some emails

Friday NAOJ Meeting
