Mysql and SMP

[Rakotomandimby Mihamina <mihamina.rakotomandimby@etu.univ-orleans.fr>]

Hi,
In debian stable/testing system, how to force mysql to use multiple CPU (I 
have Core2 Duo)? 
I host a  Database and all queries are issued by a single user/pass (the 
frontend).
When monitoring the server, mysql never span to the second core...
How to?

Thank you.
