Hello!
Has anyone tried the intel compiler for Linuxfor compiling Povray?
(http://www.intel.com/software/products/eval/)
If so, I would be interested to see the parameters. According to
http://www.open-mag.com/754088105111.htm
and
http://www.heise.de/newsticker/data/hes-11.11.01-000/ (german)
it produces much faster code. Unfortunately, I wasn't able to reproduce
this!
The rendering times I got are:
gcc 2.95.3: 4min 48s
gcc 3.0.1: 3min 41s
icc: 4min 41s
The compiler options were:
gcc 2.95.3:
-O3 -Wall -finline-functions -ffast-math -c -ansi -march=i686 -DCPU=686
gcc 3.0.1:
-O3 -Wall -finline-functions -ffast-math -foptimize-sibling-calls -c -ansi
-march=i686 -DCPU=686
icc:
-O3 -c -ip -tpp6 -rcd -axK -xK -ansi
I've used a patched version of MegaPov 0.4 with the scene furrytorus.mpg
at http://www.grafik.willhalm.de, but this shouldn't matter.
Any ideas?
