GlueX Offline Meeting, August 24, 2010
Minutes

    JLab: Craig Bookwalter, Hovanes Egiyan, Mark Ito, David Lawrence, Yi
    Qiang, Sascha Somov, Simon Taylor, Beni Zihlmann

Announcements

     1. FAQ: Mark showed the new [32]GlueX Offline FAQ. Right now it is a
        skeleton. There are two main divisions: GlueX-related and
        JLab-related. Feel free to add your questions and answers.
     2. gcc 4.4: David announced that it has been installed on the 32-bit
        farm nodes.


Review of minutes from the last meeting

    We went over the [34]minutes from the August 10th meeting.
      * New release: We are due for a new one. David thought that once a
        month is a good schedule to keep on.
      * Data file formats:
           + Beni remarked that if we do not agree on a standard file
             format, then we have given up the idea of the data definition
             being done in one place and then having that definition
             quasi-automatically propagated to places where the data is
             accessed. David answered that that idea could not and should
             not be implemented in practice in any case, because in that
             construction the objects in the programs would have to conform
             to an external data format, and it is the objects that should
             take precedence in the design of our software.
           + Sasha wondered whether we not ought to go to using EVIO
             exclusively as CLAS12 is planning to do. David wondered why he
             thought it necessary to have a single data format.
           + David argued that the issue of data format is not an issue: no
             one has complained about it or is trying to work on it. Mark
             answered that just because no one has complained does not mean
             that there are not efficiencies and simplifications in
             software development and maintenance that are worth pursuing.
           + Beni remarked that when we get around to writing output files
             from reconstruction, definition of the format should be
             tightly controlled and well documented. God-like authority was
             mentioned.
           + Mark thought that we will have to re-raise this issue again in
             the future.


Collaboration meeting offline software agenda

    We discussed talks to be given at the upcoming meeting. The current
    proposed line-up:
     1. Summary: Mark
     2. Event display: Elliott
     3. Tracking Progress: Simon
     4. TBD: David

    In the course of discussion, Sascha suggested a topic for a future
    offline meeting: the BCAL summing scheme.

HDGEANT auto-smearing

    David explained the new feature of HDGEANT that runs mcsmear
    automatically after events are generated to produced a file with
    experimental resolution introduced. He guided us through the new
    section of the [??? "control.in" file] that documents the new options.

Warnings in nightly builds

    We have been getting emails about these lately. David will look into
    it.

Action Item Review

    We went over the [39]recently resolved items along with [40]those
    outstanding.

    Some other items were suggested. For these, see the next section of
    these minutes.

New Action Items

     1. Make a new sim-recon release.
     2. Re-raise the issue of data format at a future offline meeting.
     3. Eliminate warnings in nightly builds from experimental code.
     4. Build CERNLIB on MacOS 10.6 (64-bit).
     5. Update tagger hall geometry.
