1. Nick Elias 2010 May 14 CASA Developers' Meeting1

2.  Jürgen’s talk on science priorities:  EVLA and ALMA observation modes  daunting!  ALMA depends entirely on CASA  Growing CASA user community  If CASA or ALMA fails, ramifications for the future!  Nick’s talk on the roadmap:  We’ve made progress on concerns, more to go  Requiring design documents  Formalizing closure process  incorporate comments  It will still be represented by a flowchart (sorry)  Discipline, discipline, discipline! 2010 May 14CASA Developers' Meeting2

3.  Sanjay’s algorithm talk:  Several new algorithms under development  Current development driven mostly by EVLA, but much overlap with ALMA  R&D needs isolation from main release branches  Kumar’s imaging talk:  Task by accretion  60 parameters  Described functionality of Imager and related classes  Recent history (no scratch columns, etc.)  Future (parallelization, new algorithms, etc.) 2010 May 14CASA Developers' Meeting3

4.  George’s calibration talk:  Supported calibration factors, hierarchy  Classes  Future (eliminate plotcal, ALMA polarization calibration, eliminate scratch columns, etc.)  Visualization talks:  dbus (Darrell): How does it work? Features (Qt).  viewer: (Darrell): Architecture description.  plotms: (George): History. Principles. Future.  3D: viewer  ESO IFUs. Requirements. Synergy. 2010 May 14CASA Developers' Meeting4

5.  Ger’s talk on casacore:  Recent development  Future plans  mostly bug fixing  pyrap  Jonas’ talk on the new build system:  Requirements  Build tool comparisons  Cmake  Improvements (null build times, integrated unit tests, etc.) 2010 May 14CASA Developers' Meeting5

6.  Sandra’s test talk:  List of e2e regressions  Description of unit testing system  How to run and monitor tests  Remy’s simulator talk:  CLI  Corruptions/corrections  Classes  Future plans 2010 May 14CASA Developers' Meeting6

7.  Dirk’s talk on exportasdm:  Design document created  Table formats  Features of each version of code  Binding talks:  ccmtools (Darrell): existing, somewhat complicated  boost (Wes): already used by sd tasks  swig (Michel): simple!  Wes wants to investigate boost and swig  Kumar’s VisibilityIterator talk:  Description, hints, etc. 2010 May 14CASA Developers' Meeting7

8.  Takeshi’s talk on sd:  Architecture (tools and tasks)  Recent developments (e.g., fitting, clipping, plotting)  3.0.2 plans (msmoments)  Jürgen’s demonstration of Livedata and Gridzilla:  Tools for sd observations  Dominique’s and Jean-Christophe’s talk on TELCAL:  Uses ACS  Must process data within 0.5 sec!  Many engines  Filler and calibration from CASA used  SWIG wrappers 2010 May 14CASA Developers' Meeting8

9.  John’s talk on the pipeline heuristics:  Python  Recipe driven  HTML Output  Future: Real ALMA data, parallelization  Lindsey’s talk on pipeline infrastructure:  Quicklook and science relay on CASA  Visualization, calibration, flagging, imaging  HPC:  parallel_go (Honglin): python level, how to use?  parallel (Kumar): managing memory, disk access, wrappers around parallel_go (line and continuum) 2010 May 14CASA Developers' Meeting9

10.  Process:  Kumar – Regressions (redundant, check points, documentation), research endeavor, better releases  Remy – Communications issues  Takeshi’s talk on sd data format:  Update scantable or go to ms  We have the info, a bit more discussion, then come up with plan and assign/schedule tickets  Wait for Iono-san?  Honglin’s talk on boxes:  Wow!  Nick’s talk on the release process:  A few OK ideas (e.g., unit tests), needs more work 2010 May 14CASA Developers' Meeting10

11.  “Ready for test”: can go from active to test after passes unit tests and Wes’ regressions  Scratch and R&D branches?  Check breakpoints for regression tests  Must encourage communications among developers, users, testers, etc.  Need to track regression failures  Must make time for long term planning  We have begun with viewer, HPC, and boxes  How can we effectively use Friday afternoon meetings?  E.g., scratch columns, viewer, etc.  Discipline, discipline, discipline! 2010 May 14CASA Developers' Meeting11

12.  Pictures are contained in *.tar.gz files and may be found on the meeting page  If you have additional pictures, please send them to me as well  Comments for communiqué please!  We have a new logo, thanks to Jürgen 2010 May 14CASA Developers' Meeting12

13.  The feature freeze starts now  Except for splitting cross hands  Juergen: Coordinate with workshop personnel  Everyone: Regressions started failing  Change of interpolation method?  How to coordinate fixing the regressions?  Discipline, discipline, discipline!  Patch release due o/a June 1  We may see absolute last minute bugs  be ready! 2010 May 14CASA Developers' Meeting13
