Last Meeting of the Year
Colloquium this week:
Build, Release, Testing
Update Scripts are running, every Sunday. Runs on EL5, so rapidly becoming out of date.
Last updated 2 months ago.
Need to update the scripts.
4.3 Release process
CAS-7176: Good to go on Linux
Updating ALMA ATM Library
OSX - Working on the Lattice Issues
Adding standard tools to the Mac Test System
Old VLA Filler seems to be failing in NGC-2403 test.
Systemic Velocity: IRAM want's systemic velocity from source table in the images.
Joe to work with Dirk, Kumar, Juergen to do a requirements capture.
applycal slow down has not re-occurred
plotbandpass issues fixed
importasdm XML reading issue fixed
plotting speedup factor of 2~3 in total execution time
calibrator catalog flux retrieval integration
I'm attending a full-day workshop today and cannot attend the Monday meeting.
Created a ticket to have functional tests for applycal. We need reference tests on MSs in order to test applycal on Multi-MSs. CAS-7199.
Resuming my MMS tests on the pipeline. The seg fault on plotms is "gone". I build the pipeline with the release-4_3 branch. I'm analyzing setjy to see how it can be improved to run on MMSs.
Merged fixes to the consolidation of some sub-tables from trunk to release 4.3 branch. These changes fix problems when the WVR spw is alone in a sub-MS.
improvements to low SNR bandpass calibration - antenna flagging support
general release testing
Worked on implementing VI/VB2 in plotms with various data selections (no averaging yet) as a first step.
Worked mainly on understanding some ALMA data mosaic slowness
Wrote code to cache the pointing for all antenna at all integration time
Fixed a crash with WProjection with large cubes that Emmanuel found
Justo González Villalba
Fixed cluster issues reported by Jenkins for MACOX 10.8: It was necessary to update foolscap and add OpenSSL
Investigated flagdata/flagcmd issues reported by Jenkis for all OS:
It was a problem due to the recent mods in VI/VB tile caching, I've tested a mod provided by Jim which fixes the problem
Worked on alma-cycle 2 parallel regression case using the maximum number of sub-MS possible: 428 sub-MSs
Found issues in wvrgcal which crashes after seg. fault. when processing a MMS as a MS. I've reported this to Dirk (CAS-7200)
Found performance issues in flagdata running in list mode (11190 commands): It seems that even if the MSSElection parsing time is not too large for this case (5mins) it is a big penalty to pay this time for each sub-MS when the number of sub-MS is quite large. I've created a ticket for it (CAS-7201)
Found an issue with CMAKE that is not setting the library paths properly and it is necessary to set LD_LIBRARY_PATH manually
Wrote response to CASA Users Committee.
CARTA make problems (help from Jim)
CARTA colormap & histogram GUI.
CARTA crash problems
Committed first phase of stats framework which includes ClassicalStatistics class. Modified LatticeStatistics to use new stats framework which provides significant performance improvement over previous implementation.
CAS-7176: continued testing of applycal; added fixes for channel selection and the uvcontsub context. No new reports of slowness since Jim's casa tile cache fix.
Continued investigations of I/O patterns underlying applycal (prompted by CAS-7176), most notably concerning the difference in physical data sort in DATA and CORRECTED_DATA.
4.4 Development: System Velocity, related changes to import/export UVFITS, extension of import FITS IDI
Resumed work on automask (worked on framework, extended a test version simple autoboxing code to a cube)
Wrote a python function to extract information from the fluxscale returned dictionary and to format them to write to HISTORY subtable (CAS-2152)
Commented on CAS-6991 regarding to the current caltable format
Ger van Diepen
Created nov14 branch of Googlecode casacore
added casacore/ to #include paths to get standard -I paths
Backward compatibility is available for, say, one year
The nov14 branch will be the basis for the unification
Casacore will move to github; Malte is preparing the move
Helped Shinnosuke in building CASA against this branch. When building CASA I see very many warnings of which some look serious; e.g. uninitialized variable or use parentheses in mix of || and &&. They should be taken seriously; in Casacore the || && parentheses warnings lead to 4 bug fixes, because some think that || and && have equal precedence.
All NRAO changes in casacore till 9-Dec-14 are merged in
Started working on article for special data model edition of A&C
