<div class="moz-cite-prefix">Hi Paul,<br>
yea! I see a very similar thing. I run single threaded but with
two different groups<br>
once using hd_root and once using hd_dump both with my plugin. The
group<br>
using hd_root is consistent in itself and the group with hd_dump
agrees with<br>
the group of hd_root except for one run! And yes its event 1339!<br>

<div>I ran 32 single-threaded jobs with the new software, and I
see nearly identical results, but not quite. Half of the REST
files have one identical file size (and identical contents), and
the other half have a different identical file size (and
identical contents). This is true whether I run with saving the
time-based tracking results or the wire-based tracking results
to REST. The attached "diff" files show the difference for each
case (via hddm-xml). </div>
<div><br>
</div>
<div>This difference is isolated to one event: #1339 in the file I
linked everyone to a week ago. In fact, while three wire-based
and time-based tracks are listed, they all have the same
candidate id: 2. </div>
