<p>We went over the <a rel="nofollow" class="external

href="https://halldweb.jlab.org/wiki-private/index.php/2018_Work_Packages">Work
Packages</a> presented at last week's collaboration
meeting in Sean's <a rel="nofollow" class="external
text"
href="https://halldweb.jlab.org/doc-private/DocDB/ShowDocument?docid=3757">Reorganization
of Working Groups Discussion</a> talk. There was a lot
of discussion. Some random notes:
</p>
<ul>
<li> <b>Produce a version of HDGeant4 which works as a
drop-in replacement for HDGeant</b>. The HDGeant4
item already has a mechanism in place to prosecute the
work.</li>
<li> <b>Update and generalize tree_to_amptools</b>.
This item originally came from Alex.</li>
<li> <b>Create user-friendly set of amplitude analysis
scripts</b>. Alex has started work on this one.</li>
<li> <b>Implement converter from generic output format
(HepMC?) into HDDM</b>. This one originated from
Marie Boer. She was trying to convert output from her
event generator into a from that could be used by
HDGeant.</li>
<li> <b>Refactor gen_amp amplitude definitions to
provide general common amplitude definitions for 1
and 2 meson production</b>. There was some doubt
about whether this is practical to implement.</li>
<li> <b>Tune generic MC to better describe data</b>.
This includes addressing the invariant mass
distribution generated by bggen for several of the
possible final states.</li>
<li> We noted that many of the items are related to
streamlining use of AmpTools.
<ul>
<li> Alex will mention these at the Amplitude
Analysis meeting.</li>
</ul>
</li>
<li> Beni suggested that we might need a code review of
the analysis library. There are rumors of bugs living
there.</li>
<li> Mark pointed out that the reconstruction code could
stand a review as well.</li>
<li> Thomas has started working with Simon on tracking.</li>
<li> Sean suggested someone be in charge of revising the
list. He and Mark volunteered.</li>
<li> Alex pointed out that students will solve many of
these problems, but the solutions will disappear after
they move on. Mark remarked that those solutions are
often not in a form that can be used as a general
tool.</li>
<li> Thomas thought that the work should be organized in
small groups, each with a convener.</li>
<li> Beni thought that group leaders need to push these
issues, otherwise it will be difficult to get people
to work on them.</li>
</ul>
<h4><span class="mw-headline"
id="Upcoming_Hall_B_Farm_Usage">Upcoming Hall B Farm
Usage</span></h4>
<p>David has assured Hall B that we will not be using the
JLab batch farm heavily during the next few weeks and
they should be able to get a lot of jobs through during
this period.

<p>We went over <a

title="GlueX Offline Meeting, September 18, 2018">the
minutes</a> from two weeks ago.
</p>
<h4><span class="mw-headline" id="Launches">Launches</span></h4>
<p>Alex reported.
</p>
<ul>
<li> The 60-channel analysis launch on Spring 2017 is
complete.</li>
<li> A similar launch on the 2016 Golden Period is
almost done.</li>
<li> Alex is collecting a new set of reactions another
analysis launch to start soon. He will go back to the
standard scheme of one input rest file per job.</li>
<li> He is thinking of doing a launch every two weeks or
so, each with a newly selected list of reactions.</li>
<li> Thomas has added the output tree name to the
database for easy reference by users.</li>
</ul>
<h4><span class="mw-headline" id="NERSC">NERSC</span></h4>
<ul>
<li> David is working on the documentation for a new
allocation request to NERSC.</li>
<li> Sean mentioned that the calibrations for another
monitoring launch on Spring 2018 data are ready.</li>
</ul>
<h4><span class="mw-headline" id="Computing_Review">Computing
Review</span></h4>
<p>Curtis, David, and Mark will meet Thursday to discuss
plans for the upcoming review.
</p>
<h4><span class="mw-headline"
id="Hardware-Needs_Meeting_with_SciComp">Hardware-Needs
Meeting with SciComp</span></h4>
<p>There will be meeting with Chip Watson on Thursday at
4:00 pm to discuss future hardware needs for GlueX.
Interested parties should contact David for the details.
</p>
<h4><span class="mw-headline"
id="New_Version_of_MCwrapper">New Version of MCwrapper</span></h4>
<p>Thomas reported that this will be out soon. It
incorporates fully automatic job submission, i. e., web
requests will initiate a full submission of jobs to the
OSG.
</p>
<h3><span class="mw-headline"
id="Review_of_recent_pull_requests">Review of recent
pull requests</span></h3>
<p>No significant comments.
</p>
<h3><span class="mw-headline"
id="Review_of_recent_discussion_on_the_GlueX_Software_Help_List">Review
of recent discussion on the GlueX Software Help List</span></h3>
<p>On the "<a rel="nofollow" class="external text"
href="https://groups.google.com/forum/#%21topic/gluex-software/lBh4R6B0j68">events
lost due to vertex fit for Lambda</a>" thread, Sean
will have a look. He thinks that there may be a bug in
the combo maker.
</p>
<h3><span class="mw-headline" id="Meeting_Time">Meeting
Time</span></h3>
<p>Mark proposed moving the meeting time from 2 pm to 3 pm
(similarly for the HDGeant4 meeting) to avoid the
monthly conflict with the Computing Round Table. No
objections were raised. Look for the change to your
calendar.
