My server has a 3.4 P4 with Hyper-threading.  I recall when this was  
a Windows box, that the Task Manager would display two processor  
windows.  I don't really understand the nuances of the P4, but I'm  
assuming that it somehow fools the OS into behaving as if there were  
two CPUs.

Now running linux on the same box; When I run two instances of  
mprime, both of them run at 100%.  Is it fair to assume that I'm  
getting full output out of both of them?  How do I tell?


Frankly I'm more concerned about energy consumption on this furnace  
then performance.  It has to be huge.  I recall this processor idled  
at about 58C and often ran up to about 75C.  Never had a failure.  I  
confirmed that the cooling system was properly installed several  
times.  (The machine ran too hot to use as a desktop machine: Heated  
up the room.  Not very efficient.)

Thanks, Heath
