GlueX Offline Meeting, October 21, 2009

Minutes

   CMU: Curtis Meyer
   JLab: Craig Bookwalter, Mark Ito (chair), David Lawrence, Simon Taylor,
   Beni Zihlmann

Review minutes from [29]last meeting

   How Timing Is Done in GlueX: Craig has checked som stuff in, in
   particular a new DTime class. He has not had time to play with the
   internals yet, but will start this week. Simon has been in contact with
   him with some guidance on the TOF.

   JLab batch farm priority: We actually invoked a period of [30]increased
   priority last week. That seemed to work well; the increased through-put
   was noticeable.

   Coding Standards: David has started work on [31]this, modifying the
   CLEO standard for our purposes, mainly in the "style" section so far.
   He will report on his work at the next meeting.

   12 GeV Project Schedule, Offline Computing: Eugene Chudakov, David, and
   Mark will meet on this subject tomorrow.

Announcements

     * Nightly builds are running again.
     * The [33]meeting time scheduler is up. We are deciding on a new time
       for this meeting. Go to the scheduler to veto your least favorite
       offline meeting times.


Separating HDDS (geometry definition) in the builds

   Mark led us through [35]issues involved in separating our geometry code
   from the main source code tree. We agreed that this was a good thing to
   do and that Mark will work on it.

Renaming of DTrack, DPhoton classes

   Simon reviewed the recent [37]reorganization of some of our
   reconstruction classes so that their names more accurately reflect
   their functions. He has modified hdview2 to follow this change, but
   there are other programs that will need changes.

Action Item review

   We quickly ran through the [39]list. We noted that recent work on
   multi-track final states by Simon and David has resulted in some
   significant improvements, relaxing assumptions only valid for single
   tracks.
