<ol>
<li> We are in strange situation where recent <b>Fedora
and Ubuntu releases</b> use GCC compilers that are <b>too
advanced for ROOT6</b>. ROOT5 must be used. This
situation is not expected last too long; there are
fixes on the ROOT Git master branch.</li>
<li> Sean Dobbs has a proposal for managing
run-period-dependent shifts in detector geometry. He
will describe it at the next Offline Meeting (after
the Collaboration Meeting).</li>
<li> Our <b>group disk has been expanded</b> from 700
to 800 GB.</li>
<li> To build <a rel="nofollow" class="external text"
href="https://mailman.jlab.org/pipermail/halld-offline/2016-September/002478.html">sim-recon
on Mac OS X</a> you need the C++ compiler from Xcode
8. You need to be on El Capitan or higher.</li>

Meeting Report</span></h3>
<p>Mark went over <a rel="nofollow" class="external text"
href="https://markito3.wordpress.com/2016/09/23/scicomp-meeting-september-22-2016/">his
notes from the meeting on September 22</a>.
</p>
<ul>
<li> There is still a plan to institute a formal process
for requesting time on the batch farm.</li>
<li> New farm nodes are to installed soon and will be
running CentOS7. The native compiler is GCC 4.8.5,
good enough for our software. Although a CentOS7 ifarm
node is available now (ifarm1402), it does not have
all of the packages we need to build our software yet.</li>
<li> The Lustre problems we have been experiencing have
been seen on similar systems at Fermilab.</li>
<li> Machines from 2011 are about to be retired from the
farm. Beni asked if it was possible for us to acquire
some and deploy them in the Counting House. Mark will
look into it.</li>
</ul>
<h3><span class="mw-headline" id="Launches">Launches</span></h3>
<p>The ver02 reconstruction launch had problems with
less-than-optimal calibration constants. Although the
analysis launch from that launch ran, Paul M. and Alex
A. decided to run another analysis on ver01 REST files,
using updated plug-ins. This <a rel="nofollow"
class="external text"
href="https://mailman.jlab.org/pipermail/halld-offline/2016-September/002477.html">Analysis
Launch ver04</a>. All four batches are complete now.
</p>
<p>David asked if the analysis launch was I/O bound. The
answer is not known at present.
</p>
<h3><span class="mw-headline"
id="Review_of_recent_pull_requests">Review of recent
pull requests</span></h3>
<p>We went over <a rel="nofollow" class="external text"
href="https://github.com/JeffersonLab/sim-recon/pulls?q=is%3Aopen+is%3Apr">the
list</a>.
</p>
<p>There is currently a problem producing compressed HDDM
files introduced at Pull Request #544. The b1pi test has
been failing as a result. Richard Jones is working on
the fix.
</p>
<p>Beni raised the problem of maintaining all of the
SConstruct files in all of the private plugin
directories scattered around the Collaboration. Recently
several folks could not build there plug-ins due to a
change in the standard SConstruct. No easy solution
occurred to us. We will have to discuss this in the
future.

<p>Due to <a rel="nofollow" class="external autonumber"

recent security changes at JLab, web-based programs may
need access to a JLab CA certificate to work properly.
In particular, GitHub access using HTTPS may be
affected. <a rel="nofollow" class="external text"
