<h3><span class="mw-headline"

of Minutes from the Last Software Meeting</span></h3>
<p>We went over the <a

title="GlueX Software Meeting, January 19, 2021">minutes
from January 19</a> without significant comment.

<h3><span class="mw-headline"
id="Minutes_from_the_Last_HDGeant4_Meeting">Minutes
from the Last HDGeant4 Meeting</span></h3>
<p>We went over the <a
href="https://halldweb.jlab.org/wiki/index.php/HDGeant4_Meeting,_January_26,_2021#Minutes"
title="HDGeant4 Meeting, January 26, 2021">minutes
from January 26</a>. Mark mentioned that he is close
to incorporating <a rel="nofollow" class="external

Diracxx package</a> into our set of standard software.
</p>
<h3><span class="mw-headline"
id="Collaboration_Meeting_Planning">Collaboration
Meeting Planning</span></h3>
<p>We decided that it was premature to make a definite
plan for software-related talks at the upcoming <a
href="https://halldweb.jlab.org/wiki/index.php/GlueX-Collaboration-Feb-2021"
title="GlueX-Collaboration-Feb-2021">collaboration
meeting</a>. We will revisit the topic once the agenda
is announced.
</p>
<h3><span class="mw-headline"
id="Reconstruction_on_the_OSG">Reconstruction on the
OSG</span></h3>
<p>Richard gave us an update on progress toward doing
large-scale reconstruction on the Open Science Grid
(OSG). He described issues with running the jobs, which
have largely been solved. In the process of comparing
the results on the OSG with those from the JLab farm, he
did not find agreement and traced it to
non-reproducibility of the resulting reconstructed
events from repeated runs on identical data.
</p>
<p>Further investigation reveals that most of the problems
are in the Analysis Library. He continues to pursue the
painstaking exploration of the problem.

<h3><span class="mw-headline" id="Standardized_Tests">Standardized
Tests</span></h3>
<p>Sean brought up the need to step up our testing game.
We discussed ideas to both augment our current
procedures and develop new ones.
</p>
<ul>
<li> We do a build test and simple execution tests on
new pull requests. The output of the execution tests
are not examined.</li>
<li> We do a nightly build test of all GlueX software.
There is no nightly execution test done.</li>
<li> Every three days we do a reconstruction test with
the latest nightly build. There is no automated
verification of the results, just an email with a link
to selected histograms.</li>
<li> Twice a week we do a simulation test, from event
generation to reconstruction and histogram production.
There is no automatic verification of results,
although a small number of <a rel="nofollow"
class="external text"
href="https://halldweb.jlab.org/disk_management/b1pi_mean.pngquantities">are
plotted as function of calendar time</a>. The test
also suffers from low statistics.</li>
<li> There is no test of output reproducibility.</li>
</ul>
<p>Sean proposed we add this to future software meeting
agendas. Richard suggested starting a wiki page to
collect ideas.
</p>
<h3><span class="mw-headline" id="Action_Item_Review">Action
Item Review</span></h3>
<ol>
<li> Ask the Computer Center about staging the start of
jobs in time. (Mark I.)</li>
<li> Make sure that the automatic tests of HDGeant4 pull
requests have been fully implemented. (Mark I., Sean)</li>
<li> Finish conversion of halld_recon to use JANA2.
(Nathan)</li>
<li> Release CCDB 2.0 (Dmitry, Mark I.)</li>
<li> Start a wiki page to collect ideas on software
testing. (Mark)</li>
