from June 10</span><br>
<br>
We reviewed the <a href="https://halldweb.jlab.org/wiki/index.php/GlueX_Offline_Meeting,_June_10,_2015#Minutes" title="GlueX Offline Meeting, June 10, 2015" target="_blank">minutes
from last time</a>.
<br>
<br>
Paul is working on updates to the Analysis Workshop we had
in July of 2013. Much has changed and the material needs a
refresh. He will present part of his work at the Physics
Meeting on Monday. At that meeting Justin will also show
some plots of signals from the commissioning runs,
identify areas for analysis work, and identify available
plug-ins.
<br>
<br>
<span class="mw-headline" id="Offline-style_builds_on_the_Gluon_cluster">Offline-style
builds on the Gluon cluster</span><br>
<br>
Sascha proposed that we have offline-style builds on the
Gluon Cluster so that collaborators can have uniform
structure to deal with. He pointed out that the cluster is
convenient to use for newly-taken data. We had some
discussion but at some point realized that all of the
offline builds are already available on the cluster via
the group and scratch disks.
<br>
<br>
In the course of the discussion, a need for better
documentation was identified, documentation for using the
various offline builds (tagged releases, nightly builds,
etc.). Mark I. will look into getting the information out
there.
<br>
<br>
We also discussed adding a nightly build on Beni's Ubuntu
system. Beni and Mark I. will discuss this.
<br>
<br>
Related to our builds, Matt mentioned a common pitfall
using a mixture of publicly and privately built software:
inconsistent header files. This one can be very hard to
diagnose. He noted that on CLEO, the include
directories[?] contained a ".release" file that gave
version information. The build system would check these
files and give an error if inclusion of inconsistent
versions were attempted. Something to consider.
<br>
<br>
<span class="mw-headline" id="Offline_Monitoring">Offline
Monitoring</span><br>
<br>
Kei presented slides on the latest status and news. His
outline:
<br>
<ul>
<li> Status of current launch</li>
<li> Errors reported from SciComp in offline monitoring
jobs</li>
<li> Relating event numbers and real time</li>
<li> SWIF</li>
</ul>
<br>

<br>
<br>
<span class="mw-headline" id="Processing_Update">Processing
Update</span><br>
<br>
Sean described recent improvements to the system for
processing the results of the offline monitoring jobs. See
<a href="https://halldweb.jlab.org/wiki/images/b/b5/Sdobbs_OfflineMtg_OffMon_June2015.pdf" class="internal" title="Sdobbs OfflineMtg OffMon
June2015.pdf" target="_blank">his slides</a> for a description of the
work.
<br>
<br>
<span class="mw-headline" id="Spring_2015_Commissioning_Simulations">Spring 2015
Commissioning Simulations</span><br>
<br>
Sean described the status.
<br>
<ul>
<li> We are basically ready to run.</li>
<li> The new BCAL simulation is ready. The shower energy
is a few percent low, but that was the case with the
previous version of the code.</li>
<li> There are also improvement in tracking that Simon
has checked in.</li>
<li> Mark will tag a new version of sim-recon for this
effort.</li>
</ul>
<br>
<span class="mw-headline" id="More_on_Git_for_GlueX">More
on Git for GlueX</span><br>
<br>
Mark presented further thought on how we might conversion
from Subversion to Git for source code version control.
See <a rel="nofollow" class="external text" href="https://halldweb.jlab.org/talks/2015/git_for_gluex_2.pdf" target="_blank">his
slides</a> for the details.
<br>
<br>
Mark proposed that we make a decision on the switch at the
next offline meeting.
