RE: New Computer

["Thomas Droege" <tdroege2@earthlink.net>]

It is now pretty clear that my dual processor production machine is running
on one CPU.  It only got a few more stars processed than a slower machine
running the third pipeline.  This is consistent with running on one CPU. 
Sigh!  How do I get second processors turned on?  What could have made it
decide to turn off a processor?
