Yes but keyrate will not be doubled.  You lose Mhz going SMP (NOT
literally).  Fastest option would be two boxes if you have two chips.

i don't believe that they're saying that two will be faster than one...
they are saying that the key generation rate will be doubled...
especially if they run the client on both processors... i understand it
is possible to run the client on a single processor in a SMP machine...
