Details:
Hello, many many thanks if you can help with this bug or direct me to someone
who can:
I have a code which runs forward solves of Navier Stokes with a 4th order etd
method. It works fine on matlab and on octave 3.2.3 on my mac, but when i
submit to queue or even run it on the cluster here, it consistently blows up!
(as though something were wrong with the code!) Other than standard
operations, it runs a number of FFTs.
FYI - another thing I noticed consistent with octave is that it can compute
the correct mod operation only with integers. For example, try
for pp=1:1e4
if mod(pp*.025,.1)==0
q=q+1;
end
end
pp/q
!!!!
Now, see
for pp=1:1e4
if mod(pp*.25,1)==0
q=q+1;
end
end
pp/q
Correctable, OK, but disconcerting! .... something similar and not nearly as
trivial is going on above, I think.
Thanks alot again, best regards,
Kody
