I just recently got myself an ASUS P2B-D board and equipped it with two
P-III 450 processors, and everything seems to be running just smoothly and
fine with a 2.2.12-SMP kernel... BUT... There is something that is bugging
me, and it might have a very logical explaination to everybody except me
since I'm not an expert on how Linux handles scheduling between
processors. Anyway, what got my attention is that when running some number
crunching single threaded processes, I was expecting to see that one
processor was to be fully occupied, but that's not the fact, instead one
has 42% load and the other 63%, or maybe sometimes the load is dispersed
25/80 between the processors, or similarly. But the funny thing is that it
close to always seems to be a total load of 105 %... How come? If the job
gets split up between the two processor how come they aren't fully used
then?? And why is the total 105 % and not 100 % ? Just curious... :)
Anyone happen to have an explaination?
Cheers!
