Hi Mark,

No,the reason that you see 2 times as many processors as really are 
installed is the hyperthreading feature of the Xeon (see 
http://www.infoworld.com/infoworld/article/02/02/25/020225plxeon_1.html)

I turned it off (in the BIOS). The machine I tested on has 2 (pysical) 
processors installed. Turning on or off does not influence the pystone 
number significantly..
