<ul style="list-style-type: square;">
<li>Currently GlueX Team members are not allowed to
create repositories owned by team. There is a
setting to allow that privilege. Mark asked whether
we should turn that on. David suggested that we keep
things as they are; team members have private
accounts and can create and delete repositories at
will using those accounts. Mature private
repositories can be forked into the GlueX Team when
they are ready by one of the admins. We agreed with
David; keep things as they are.</li>

<li><b>New Work Disk</b>. The initial rsync of our work
disk to the new Lustre server completed last week. It
only took about 4 days. The switch-over will require a

background: transparent;">his slides</a><span
class="Apple-converted-space"> </span>for details.
Topics covered included:</p>
<ul style="list-style-type: square;">
<li>Current launch (number of jobs, nature of failures)</li>
<li>Statistics on the launch (memory use, CPU time vs.
wall time, etc.)</li>
<li>Farm environment (other jobs running in competition
with the launch)</li>
<li>Memory Usage on Farm (number of jobs memory limited,
not limited by number of job slots)
<ul style="list-style-type: square;">
<li>Hall D can be memory efficient due to JANA
multi-threading</li>
<li>Other, non-Hall-D jobs may not be as memory
efficient</li>
<li>We may be tape limited in any case. (Paul)</li>
<li>If an entire node is reserved for Hall D, then our
memory efficiency will translate into greater core
usage efficiency. (David)</li>
</ul>
</li>
<li>Moving Forward.
<ul style="list-style-type: square;">
<li>Due to new plugins, now require 8GB of RAM to run
jobs - some pruning of unnecessary histograms would
be welcome</li>
<li>Request by Mike S. that only certain runs be run
with -PBCAL:USE_TDC=1, unfortunately bug in script
made all runs processed with this option
<ul style="list-style-type: square;">
<li>a negative effect on uncalibrated runs</li>
</ul>
</li>
<li>Started on BCAL cosmics 2015-06 ver03 on September
29 (Tue)</li>
<li>Next launch is this week, October 2(Fri): no
demand for this</li>
<li>Any need for running over 2014-10 Data?: no
requests received</li>

about standard conditions to be simulated next.</p>
<ul style="list-style-type: square;">
<li>Names for projects: something like sim1, sim2,...</li>
<li>The data sets will not be necessarily tied to a
particular real data run, rather they will be generic
and can be used for studies under those generic
conditions, for example signal studies for particular
reactions or rate studies.</li>
<li>We may need a larger data set than those we have been
generating for commissioning simulations recently,
perhaps something on the scale of past data challenges.
Right now the only large data set we have is from Data
Challenge 2, and that is getting kind of old now.</li>

class="mw-headline" id="Auto-Build_on_Pull_Request">Auto-Build
on Pull Request</span></h3>
<p style="widows: 3; orphans: 3; margin: 1em 0px;
line-height: 1.2em;">Sean described the recent effort to
set up a build of sim-recon triggered by a pull request on
GitHub as we discussed at the last meeting.</p>
<ul style="list-style-type: square;">
<li>He, Nathan, and Mark met with Marty Wise and he has
installed some packages on halldweb to support the
system.</li>
<li>The system uses the "gluex" user on GitHub.</li>
<li>Mark put together the scripts to do the build.
Although initiated on halldweb, the build is executed on
the ifarm.</li>
<li>The CGI script on halldweb not only initiates the
build but reports the results back to GitHub as a
comment on the originating pull request.</li>
<li>There seems to be an issue having the entire process
succeed from GitHub's point of view, possibly because
the build takes a while and the system may be timing
out. The build itself seems to succeed.</li>
<li>The system is not active yet, but will be turned on
once this last issue is solved.</li>
</ul>
<h3 style="page-break-after: avoid; font-weight: bold;"><span
class="mw-headline" id="Noise_Studies">Noise Studies</span></h3>
<p style="widows: 3; orphans: 3; margin: 1em 0px;
line-height: 1.2em;">Sean showed some initial results from
a study comparing raw hit distributions between simulated
E&M background data and pair spectrometer triggers.
See<span class="Apple-converted-space"> </span><a

style="color: inherit !important; padding: 0px
!important; text-decoration: inherit !important;
background: transparent;">his slides</a><span
class="Apple-converted-space"> </span>for all of the
plots. There are a number of large discrepancies, but at
this stage there were a lot of questions about whether the
comparisons were fair. It does appear that the pair
spectrometer triggers have a large prompt component. If
that conclusion holds up, then those data would not be
useful for these comparisons. If a random trigger could be
set up, that would solve the problem.</p>
<p style="widows: 3; orphans: 3; margin: 1em 0px;
line-height: 1.2em;">Mark remarked that it would be very
nice if we could understand the comparison. In particular,
it would give us confidence in extrapolations to higher
beam rates using simulated data.</p>
