(In reply to comment #23)
I read the discussion with a lot of interest - so here are the data for a
Pentium-M:
echo "GCC 3.x double performance:"
GCC 3.x double performance:
./xdmm_gcc
ALGORITHM NB REPS TIME MFLOPS
========= ===== ===== ========== ==========
atlasmm 60 1000 0.281 1537.37
echo "GCC 4.x double performance:"
GCC 4.x double performance:
./xdmm_gc4
ALGORITHM NB REPS TIME MFLOPS
========= ===== ===== ========== ==========
atlasmm 60 1000 0.265 1630.19
echo "GCC 3.x single performance:"
GCC 3.x single performance:
./xsmm_gcc
ALGORITHM NB REPS TIME MFLOPS
========= ===== ===== ========== ==========
atlasmm 60 1000 0.281 1537.37
echo "GCC 4.x single performance:"
GCC 4.x single performance:
./xsmm_gc4
ALGORITHM NB REPS TIME MFLOPS
========= ===== ===== ========== ==========
atlasmm 60 1000 0.266 1624.06

So I guess the first column gets another entry: Pentium M
