I've performed a benchmark test for Prescott 3.0 GHz CPU. The results seem
to be dependent on a "-xP" switch.

Hardware + Compiler: P4 3.0 GHz (Prescott), ifort 8.1 + mkl7.0.1

1) OPTIONS = "-FR -mp1 -w -prec_div -r8 -pc80 -pad -ip -DINTEL_VML"
246.510u 0.700s 4:12.75 97.8%   0+0k 0+0io 762pf+0w

2) OPTIONS = "-FR -mp1 -w -prec_div -r8 -pc80 -pad -ip -DINTEL_VML -xP"
236.530u 0.650s 4:02.38 97.8%   0+0k 0+0io 780pf+0w

I hope it helps.
