Just a stupid question. No, unfortunatelly I still didn't found a magic
flag (trying to be in touch with the intel premier support still).
Anyway, I was trying to grep every invsqrt in gromacs directories, and
after verbosing out strings like "invsqrta", "_invsqrt", "invsqrtdata",
"vecinvsqrt", "invsqrtm", "invsqrtfracttab" and "invsqrtexptab", and
also some comments stuff... Well, the command line below:<br>
<br>
grep -Hni 'invsqrt' -r * | grep -v 'Arquivo' | grep -v '#' | grep -v
'icc' | grep -v 'gcc' | grep -v 'pgi' | grep -v 'intel' | grep -vi
'.bak' | grep -v 'html' | grep -vi 'invsqrta' | grep -v '_invsqrt' |
grep -v 'invsqrtdata' | grep -v 'vecinvsqrt' | grep -v 'invsqrtm' |
grep -v 'Software' | grep -v 'fast' | grep -v 'invsqrtfracttab' | grep
-v 'invsqrtexptab' | grep -v 'version'<br>
<br>
I finally arrived to 57 entries to invsqrt. Just before start, and
since I'm not good at C (F90 addicted), are those 57 entries in only 12
files all that I should have to modify (I expected little more)? Just
in case, I'm attaching the output from that load of "piped greps".<br>
<br>
I'll be working on it tonight, and hope tomorrow I'll have more news on it. I'll, if those are the only lines of code to change.<br>
<br>
Despite of that, I've made a trial without the --disable-x86-64-sse flag for config. The compilation fails at another point now:<br>
<br>
*************************************************************************************************************************************<br>
/bin/sh ../../../../libtool --mode=compile /usr/bin/gcc -O3
-ffast-math -funroll-all-loops -fpeel-loops -c -o

make[5]: ** [nb_kernel010_x86_64_sse.lo] Erro 1<br>
*************************************************************************************************************************************<br>
<br>
I found some information on this kind of error from libtool on google
(something about compiler changing in different parts of compilation
process), but I'm not finding a way around this. Does anybody has any
idea on this, please?<br>
<br>
Thanks a lot for everything in advance.<br>
