News / Management
  • SW Engineer Christina Reynolds starting 11/21 in CV - assigned to CARTA
  • SW Engineer Andrew McNichols starting 11/26 in CV - assigned to Infrastructure Modernization
  • Latest Infrastructure Modernization Plan updates:
  • ADASS Highlights
    • Data Visualization
      • 3D, VR
    • Machine Learning
      • NN's, CNN's, Deep Learning
      • Auto-classifying features in image data

  • Calibration and Flagging
    • Started looking at some failures of test_flagdata in CASA 6. There were issues with the third party libraries for CASA 6 in conflict with the existing libraries. Darrell provided a way forward. In progress...
  • Imaging
    • CAS-11191 optimized the code a bit for doing a convolution function per baseline per time. Found a bug in the pointing table reading code when interval is not set.
    • Design for parallel tclean/imager in C++ attached below; Green boxes -->serial case and red arrows --> some form of message passing.
  • Measurement Set
    • Started multiple SPW combination for VI/VB2
  • Image Analysis
    • CAS-12034 investigate perceived slowness in ia.calcmask(). Investigated. 1/3 time spent computing LEL, 2/3 time spent copying (read/write) LEL data to mask data, so this is mostly an I/O bottleneck. Conclusion: writing a 3 Gpixel mask to disk is going to take a non-negligible amount of time. The code to do this is very low level in casacore Lattice class and used practically everywhere in casa for lattice copies, so, it is likely this is as good as it gets. (DM)
    • CAS-12032 fix bug in specflux exposed by CASA6 test failure. Resolved. (DM)
  • Casacore
    • CAS-12043 squash OSX clang compiler warnings in measures. casacore PR submitted. (DM)
    • CAS-11994 squash OSX clang compiler warnings in tables. Resolved (DM)
  • Data Visualization
    • N/A
  • CASA 6
    • Tool and Task build and test Dockerized. (VS)
    • Tool wheels are now automatically uploaded in the artifact repository. Haven't had a clean build of tasks yet.(VS)
    • Updated Nexus. (VS)
    • Submitted a helpdesk ticket to have "official" SSL certs installed. This will probably require more planning and negotiation. (VS)
    • CAS-12009 fix failing immoments tests. Resolved. (DM)
    • CAS-12008 fix failing imsmooth tests. Resolved (DM)
    • CAS-12007 fix failing specflux tests. Resolved (DM).
    • CAS-12002 rationalize ms.statwt() and task statwt tests in casatools and casatasks. Resolved. (DM)
    • CAS-12006 fix failing immath tests. Resolved (DM)
    • CAS-11991 rationalize ia.boxcar(), ia.hanning() and task specsmooth tests in casatools and casatasks. Resolved (DM)
    • There are still 13 remaining test failures (but JIRA tickets have been created for all failures)
    • Tasks which have no test cases (note that tool tests no longer run any task tests):
