That's exactly what it means. I allow more than one actual frequency for any particular CPU (in your example "Pentium 4 3.20GHz") so that you can compare the effects of overclocking to different levels.

When you overclock from 3.00 GHz to 3.60 GHz, isn't that a 20% overclock instead of 40%?

Default mprime 24.14 on 4-core WoodCrest : not scalable ?!

Hello,

I've run mprime 24.14 in // on the 4 cores of a 2-chips 2-cores of a Woodcrest machine, and the results show that this kind of machine is not scalable for mprime.
(Measures have been made 3 times to check).

You're absolutely right. I did realize that, but I could no longer edit my post...
