Re: Polyhedron Benchmark


Hello!

I did a quick comparison on an Intel Core2 Duo T7300  @2.00GHz using
(-m64) using:

gfortran -march=native -ffast-math -funroll-loops -ftree-vectorize
-ftree-loop-linear -O3

Could you perhaps add -fvect-cost-model to gcc-4.3 compile flags? There are some surprises there ;)


Uros.
