moz-do-not-send="true">Issue #143</a>: BCAL reconstructed
energy sometimes broken on startup: multicore only. Richard
has been able to reproduce the problem of significantly
different BCAL energy distributions on repeated runs of
HDGeant4 with a 2 GeV photon particle gun at 60 degrees. This
appears to only happen when hdgeant4 is run in multi-threaded
mode. We generally build hdgeant4 against a multi-threaded
build of Geant4, but even so, single-threaded mode for
hdgeant4 seems not to be a problem. Richard noted that our
running on the OSG is always single-threaded. Now that he can
reproduced the problem, he will turn to its solution.</li>

he presented last time with this branch and compare.</li>

Action Item Review</span></h3>
<ol>
<li> Richard encouraged us to get started on preparations to
advance to latest Geant4 release G4.10.06. Mark will build a
version set, based on this release, and let Sean et al. know
so they can do some comparative studies before we unleash the
new release on the collaboration.</li>
<li> Richard has discovered 20% reduction in cpu time from
killing particles that go beyond the walls, floor, and ceiling
of the Hall in the simulation.</li>
<li> Investigation of the multi-threaded bcal photon gun
anomaly, discussed above.</li>
<li> Investigation of the backward kaon efficiency step at 120
