Subject: How well do today's "Deep" engines scale?

There is a wealth of choice in the SMP hardware market today. Intel Xeons,
AMD-MP, AMD Opterons and Dual Core chips. A few years ago, Deep Fritz 7 scaled
at around 1.6-1.7 on a Dual Intel Pentium III machine.

A few years on, hardware and software have progressed - but to what extent? All
you SMP Computer Chess fanatics, its time to post your results!

It will be interesting to see the results for the most popular commerical and
amature engines on a variety of hardware types.

Please post the nodes per second for 1 and more threads obtained when searching
the below position for around 60 seconds. Oh, and don't forget to state the
engine and hardware! It would be interesting to see how a single dual core CPU
scales in comparison to two separate CPUs!
