<h3><span class="mw-headline" id="Announcements">Announcements</span></h3>
<p>Mark mentioned that there are <b>a series of pull
requests from Simon</b> responding to a request from
Richard to modify Simon's recent changes to the hddm_s
schema, to support the CPP muon chambers, backward
compatible with existing hddm data. The pull requests are
for halld_recon, halld_sim, and hdgeant4. Once they work
their way through the system, we will need a new version
set. </p>
<h3><span class="mw-headline"
id="OSG.2FOffsite_Computing_Update">OSG/Offsite
Computing Update</span></h3>
<p>Bryan brought us up-to-date with work over the last few
years to stand up the infrastructure, both hardware and
software, that allows us to use the OSG and other off-site
computing resources. Please see his slides for the
details. From the discussion: </p>
<ul>
<li> With the new token-based authentication used in
version 3.6, there is an issue with having multiple
instances of the submit host on the same physical node.
We need this to support the GlueX, JLab, and EIC VOs. A
solutions is being developed. </li>
<li> Bryan described the difficulty in exposing our large
Lustre partitions to access from offsite via XRootD.</li>
<li> He described the plan to use existing file servers to
carve out space to serve out GlueX data on StashCache.</li>
<li> Wes gave some details on a problem accessing
StashCache data via CVMFS from the farm. Work on this is
on-going.</li>
<li> Sean mentioned the need for GlueX to communicate our
ideas on OSG-related workflows to SciComp and for
SciComp to keep us up-to-date with current work and new
directions in this area. Along these lines, Wes
expressed a desire for a channel where they can get
feedback on solutions that SciComp is pursuing. We
agreed that we should have regular meetings with
interested parties to discuss these topics, much as they
were discussed at today's meeting. Bryan will mention
the concept at tomorrow's SciComp meeting (where the
other Halls are represented), Sean will put together a
list of the workflow ideas we are contemplating and Mark
will arrange a kick-off meeting at the end of March.</li>
</ul>
<h3><span class="mw-headline"
id="Review_of_Minutes_from_the_Last_Software_Meeting.5D.5D">Review
of Minutes from the Last Software Meeting]]</span></h3>
<p>We looked at the <a

title="GlueX Software Meeting, February 16, 2022"
moz-do-not-send="true">minutes from February 16th
meeting</a>. We need to get going on a new system for
producing containers. Related to that Mark is working on
adjustments to our builds so that there is no difference
between builds on the JLab CentOS 7 farm nodes and those
produced with a CentOS 7 container. Then these two builds
can be consolidated into one and this single build can be
shipped to Oasis for use off-site. </p>

<p>We looked again at Alex's <a

<p>Alex also mentioned that Chris Larrieu liked <a

href="https://groups.google.com/g/gluex-software/c/F3u3wQSS0CI"
moz-do-not-send="true">the related discussion on the
Software Help list</a>, but Chris lamented the fact that
folks in the other Halls will not benefit from this and
similar exchanges. Mark mentioned that <a rel="nofollow"

the ground. </p>
