News / Meetings / Visitors

• Jeff in CV next week, ANASAC and UC
• NRAO Holliday Monday
• ESO Developers Visit June 5-9
• CARTA Meeting June 19-23
• SKA Meeting -- Meeting between DMS mgmt and SKA to create an MOU for advancing the data model for CASA -- make CASA scale better for parallelization. Agreed to work on MSv3. Our current HPC effort scales to hundreds of cores. SKA needs a model that scales to thousands of cores. Timescale is a year. This will be run as a subproject of casa. However, SKA will be doing the work and mostly managing the project.
• VLASS CDR was this week. Still technical requirements that are in flux. Not many action items likely to come out of the CDR for CASA. There are 2 blockers: additional DA support needed; discrepancy in polarization calibration must be understood.

Build, Release

• 5.0 status
  • User testing of tclean on going.
  • Problem with frequency axis.
  • Mask / tclean issues
  • CAS-10110
  • Documentation display issues that need to be fixed.
  • Lindsey's doc error messages: we depend on web browser modeule from python; it depends on stuff that Linux/OSX provides for opening browser. It might be good to catch the error and generate a human-readable error message.
  • Final documentation review on week of June 5th.

Verification Testing

• Moved one of the test Macs to a build Mac
  • Needed to keep up with Bamboo builds
  • OSX 10.12
• CASA guides are not working, so for now they have been taken out of the test suite
  • Certain machines only see data-local, but CASA guide data is in data-shared
  • Will be put back in after the 5.0 release
• Both master and prerelease are looking at the same test directory
  • New tests in master will not work in prerelease
  • New tests will be put in after the 5.0 release
  • There will be some discussion within the build and test teams, and decisions made on how to manage this issue without impacting the CI system

Validation Testing

• Testing of VI/VB@, tclean, calibration

Architecture

• Warnings Summary

HPC

Development

• CASA 5.1 Planning: VLASS, pipeline, asynch I/O stuff.
  • There are 256 miscellaneous tickets.
  • If you don't know what you should be doing for 5.1, talk with Jeff, Morgan, or Anand.
  • Asynch I/O: Jeff wants to do CDR in 5.1 cycle; will not be turned on by default, but would like to have it ready for testing just after release.
  • 5.1P1 pipeline branch has been created.

Pipeline

• CASA5.1P1 branch created
• Release notes at https://wikis.alma.cl/bin/view/DSO/PipelineHeuristicsReleases2017
  • Release has focused on technical debt, particularly on imaging side.
    
• tclean issues
  • autoboxing problems fixed
  • cube coordinate system issue

AOB

• Eduardo Miranda's Report wrt Casa Group Lead
  • Darrell: Miranda seemed to recommend giving more power to project scientist (and lower level staff) to free lead to do long term planning.
  • Morgan is looking for a lead who is somewhere between a dictator and a coordinator.
• CASA Lead search committee. Please feel free to share your ideas with members.
  • Technical Committee Members: Urvashi, Lindsey, Darrell, Rafael;
  • Stakeholders Committee: Kumar is a part.
• Interim Coordination Team
  • Members:
    • Darrell - build / system
    • Urvashi - science
    • Jen - testing
    • Juergen - project scientist
    • Lindsey - pipeline
    • Anand -
    • Morgan - interim lead
    • Sandra - ESO
    • Kana - NAOJ
    • Shin Fey Lee - ASIAA
  • Andy was considered for this group, but mostly he will not need to attend.
  • This type of management team was tried in the Rob Selina era. It worked.
    

Developer Reports

Monday Meeting

• Sanjay Bhatnagar
• Sandra Castro
• Lindsey Davis
  • Release note preparation
  • Updates to pipeline manifest and aqua report generator
• Pam Ford
• Enrique Garcia
• Bob Garwood
  • ALMA code move related work - disentangling code generation steps from makefiles, pushing forward on syncing ALMA and CASA versions before the move.
  • Some GBT-related work.
• Kumar Golap
• Jeff Kern
  • Preparation for UC
  • VLASS CDR
• David Mehringer
• George Moellenbrock
  • VLA tour last Thursday for Socorro 4th grade. (Thanks also to Kumar for helping!)
  • Re-examined CAS-6130 and CAS-8527: there are still some problems with cal library relating to lack of availability of calibration for all spws known to an MS. Best to fix this in 5.1.
  • 5.1 JIRA planning
• Dirk Petry
• Martin Pokorny
• Federico M Pouzols
  • Thursday 25 is a holiday in Germany
  • CAS-5808: "rflag's use of timedev and timedevscale parameters", ready to verify/test.
  • CAS-9089: automatic generation of antenna position corrections from web service / ALMA TMC DB. Service time out issue just fixed after our ICT leads promoted ticket to "blocker": http://ictjira.alma.cl/browse/ICT-9872. Hoping to get this ready for testing next week.
• Urvashi Rao
• Darrell Schiebel
• Ville Suoranta
• Takahiro Tsutsumi
  • Checked in a temporary fix for tclean automask issue on nfs mounted disk for 5.0
  • Looked into on tclean 's cube image setup difference between 4.7.2 and 5.0 (CAS-10194)

Friday NAOJ Meeting

• Kanako Sugimoto
  • Fully migrated to Eclipse + EGit development environment thanks to instruction wiki by Takeshi.
  • Appropriate UNIT handling in singledishfiller ( CAS-10043): import part is done in Nobeyama and scantable filler. CORRECTED_DATA column generated by calibrator tool does not respect optional UNIT keyword while mstransform does. Need to decide what to do.
• Wataru Kawasaki
• Masaya Kuniyoshi
• Takeshi Nakazato
  • issued two pull requests (merged): CAS-9763 and CAS-9923
  • CAS-8879pre-application of sd caltables in sdgaincal
    • Start implementing FiltrationTVI that returns the data satisfying a condition given by Filter template argument
  • intermittent failure of sdimaging unit test relapsed: https://open-bamboo.nrao.edu/browse/CASA-MT-JOB1-237
    • same test, failed in the same way
  • instruction for Git-based development on eclipse (in Japanese)
• Renaud Miel
  • CAS-8082 plotms header: All requested header items implemented. Screenshot
