<div dir="ltr">Hi Steve,
<div><br>
</div>
<div>I'm using that 'fp-precise' option. The bns specific thorns
like NSTracker and RotatingSymmetry180 didn't make the issue
(and RK3 instead of RK4 is tested).</div>
<div><br>
</div>
<div>I think I might be mistaken but I've thought that TOV and
BNS use different initial data setup, for instance, to get the
values for _p, _p_p etc. I was suspecting that BNS might be
causing the trouble while making those data. But I've got
messy confirming what I have thought. Do you have any feeling
it's likely caused by this process? Since the TOV test didn't
encounter the issue, I think there's no more bns-specific
processes.</div>
<div><br>
</div>
<div>Thanks in advance.</div>

<p>Sorry I lost track of this email thread. I got caught up
with other things. I'm wondering whether you have tried
compiling with fp-precise? I'm just wondering whether it
could be a problem with Intel's optimization.<br>

<div>Hi,</div>
<div><br>
</div>
<div>As James Healy mentioned in the post "[Users]
Einstein Toolkit and modern AMD supercomputer", I
found static_tov.par passed the test for the Intel
issue. So some bns-generic codes would make NaNs.
But less probable because the only bns-generic code
would be NSTracker but I've already encountered the
NaN production issue w/wo NSTracker.</div>
<div><br>
</div>
<div>NaNChecker itself could be suspected but both bns
and tove tests are using NaNChecker.</div>
<div><br>
</div>
<div>Rather, it could be a generic issue of Intel
compiler. There are some bugs reported and new
features in handling NaNs for the case of ifx. Those
look just irrelevant yet.</div>
