Hello,
I would like to have the following test performed on machines similar to
mine. I openened a bug report at https://savannah.gnu.org/bugs/?32120
Test: do twice
[1+i 2+i ; 3+i 4+i ] * [5+i ; 6+i]
Expected:
ans =
15 + 14i
37 + 18i
Wrong result
ans =
17 + 11i
39 + 11i
It seems that this occurs under Ubuntu 10.04 LTS on i686 machines, with
library libatlas3gf-sse2, version 3.6.0-24ubuntu1: i386, installed. Could
peoples having access to I686 machines running either Ubuntu 10.04, either
debian stable, test if
/usr/bin/octave -f
generates the wrong result, AND
LD_PRELOAD= /usr/lib/libatlas.so.3gf /usr/bin/octave -f
gives the right result ? This would indicate bugs in libatlas-sse2 "ZEMM"
implementation.
Thanks in advance
Pascal Dupuis
