Developer Reports

Monday Meeting

• Sanjay Bhatnagar
• Sandra Castro
  • CAS-5833: looked into mscal and MSInterface as possible solutions for applying selections in the SYSPOWER table. Sanjay is also looking into this.
  • Added a patch flagdata's parser for input lists to support another exceptional use-case in flagdata. (CAS-6553).
  • Justo and I found problems in mstransform when the input is an MMS (CAS-6543). We need to tackle these problems soon.
  • Building and running tests on release-4_2_2 in linux and OSX.
  • Many non-CASA meetings.
• Lindsey Davis
• Kumar Golap
• Justo González Villalba
  • Prepared and ran a parallel version of CASA vs AIPS test using SCO Lustre cluster. Produced report to highlight performance gain and scaling.
  • Keep preparing "Installation and advance user guide" for the MPI-based parallel processing framework. I have 75% ready (16/25 pages). I hope to finish before Thursday presentation.
  • Discussed mstransform parallelization and partition issues with Sandra (CAS-6543). After MPI documentation release we plan to focus on fixing these problems.
• Jim Jacobs
• Jeff Kern
  • Attempting to get job opening posted
  • Prepared slides for User Committee Meeting
  • Contribution to ICT SPIE Paper
• Susan Loveland: Worked on integrating new PixelValueManipulator into Profiler with Dave's help; worked on CARTA UI prototype.
• David Mehringer:
  • Iterated with Susan on integrating PIxelValueManipulator into the profiler, tried to understand the intent of some strange functions currently used by the profile/ImageAnalysis::getFreqProfile() (CAS-6354);
  • added support for complex-valued images to ia.fromarray() for Sanjay et al. (CAS-6510);
  • implemented msmd.namesforspw() (CAS-6459);
  • investigated CAS-6496 and concluded imfit was behaving as designed and documented in this case, but handed back to reporter in case they wanted to make further comments;
  • looked at AipsIO::getNextType() exception context in response to Justo's casa-staff question and reported my findings
  • fixed CAS-6497, newestimates file not being written by imfit;
  • responded off-list to Jeff's memory leaks query to casa-staff;
  • fixed bug causing test_imcontsub to segfault;
  • began groundwork for reporting spw center frequencies in listobs (CAS-6484)
• George Moellenbrock
  • Summer School Calibration lecture prep and delivery, plus various discussions with students
  • Summer School tutorials
  • (Urgent) Analysis of weight/sigma handling in split; Dirk and I will be sorting this out in the coming week
• Dirk Petry
  • discussed weights with George
  • discussed integration of almawvr code into CASA codebase with Scott (code will be put into 3rd party part of repository)
  • some tests on the CASA 4.2.2 branch
  • started work on FITSIDI filler extension
  • (for brevity, I will not list work here which is not directly CASA-related)
• Scott Rankin
• Urvashi Rao
  • Added support for NCP image projection in (new) imager, as a special case of SIN. This is for ATCA, requested and tested by Mark Wieringa.
  • Attended several synthesis imaging school lectures, lots of user support via tutorials and independent requests.
• Darrell Schiebel: worked on DBus VO Client (fixed laptop sleep/awake crashes), spent a lot of time trying to build gfortran for a clean install of OSX 10.8 (still not quite there)
• Rob Selina
  • (On vacation last week)
• Takahiro Tsutsumi
  • CAS-6530 : wrote a method to concatenate componentlist for multiple spws and modified existing code to work with it.
  • Vacation: 5/15-5/19

Friday NAOJ Meeting

• Kanako Sugimoto
  • Finalized the plan of CASA 4.3 developments
  • CASA 4.2.2 review & CASA 4.3 kickoff meeting
  • Review of new unit tests of SD tasks implemented during CASA 4.2.2. cycle. Gave feed back to Takeshi and Wataru.
  • Vacation (next week): May 19th - 21st
• Wataru Kawasaki
  • modified unit tests for sdgrid and sdplot
  • fixed a bug in sd.scantable.sub_baseline()
  • found a minor bug in sd.plotter. reported it to Kana.
• Takeshi Nakazato: Fixed sdcal2 unit test failure, spent most working time for pipeline development
• Shinnosuke Kawakami: code reading of taskmanager.py ( about IPython MultiEngineClient system) and ipython-doc of ipython.org

Build, Release, Testing

• CASA 4.2.1 Released publicly.
  • Outstanding issue from Remy will be pushed to 4.2.2
  • Helpdesk reported a similar issue to Remy's, so we may want to add this to the list of known issues.
  • Switch implemented for QA2 in ALMA.
• CASA 4.2.2 Merging, Testing, etc
  • George tidying up split and related tasks finalizing the weights implementation. Will work with Dirk on this while here this week.
  • OSX 10.7 and 10.8 will be officially supported (not 10.9).
  • RHEL pre-release package is priority over OSX at this point. Will split the package release as we did for 4.2.0/4.2.1.
  • Scott working on merging the changes committed to trunk. The build works on RHEL but fails on OSX at the moment.
  • George working on a developer build to verify weights changes in isolation. Scott may have asked a few other developers to test commits in isolation.
• Archive retrieval version of CASA for the VLA - IERS table in repository
• Trunk build tested last week (including weights) by Crystal and others.
  • Darrell prepared a developer build to see the changes in the weights implementation.
  • Extended testing on the 4.2.2 pre-release packages.

Architecture

• Technical Forums: Justo, MPI, Thursday 5/22. Justo working with helpdesk to connect to presentation remotely. Justo sent URL to Jim and Jeff to test the presentation.
  • 6/5 - (Need a Volunteer)
  • 6/19 - ESO Holiday

Development

• CASA 4.3 progress.
• Items requiring clarification

Pipeline

• N/A

AOB

• Dirk - presentation this Friday by Jim? Need to confirm, likely at 2pm or 1:30pm. To be confirmed.
• 10.9 support - Juergen has people testing the 4.2.1 OSX release on 10.9. George will test the release on his new laptop.
