Subject: benchmark test for fun (and for Vincent)

If anyone has the time, and a dual-cpu machine, would you run the following
position to depth 13 using first one cpu, then restarting, and running it again
with two processors?  Everything else at default values.

2r2rk1/1bqnbpp1/1p1ppn1p/pP6/N1P1P3/P2B1N1P/1B2QPP1/R2R2K1 b - - 0 1

That is kopec position 22, one of my favorites.  I am only interested in
two numbers, the raw NPS for 1 cpu, and the raw NPS for two cpus.  I don't care
about the times or anything, just the NPS...

Please include your cpu/speed/vendor/etc...

Vincent thinks that the 2-cpu test will slow way down in terms of NPS.  I
can't reproduce it on my machines here.  Eugene can't reproduce it on Intel
boxes, but the two AMD machines he has tried produce 1.4X the nps using two
that it produces using 1, while my machines produce about 1.9X the nps...

Thanks...
