SMP aware programming

[Nikola Knežević]

Hi,

I'm about to port ModelNet (a large-scale internet emulator) from  
FreeBSD 4 to FreeBSD 7. It is implemented as a module. Well, changing  
couple of headers and structs will probably solve the thing, but I  
would like to make it SMP aware. Since it emulates a lot of nodes,  
each of which is doing some processing, I would like to "group" them,  
so ones are executing on one core, other on second and so on...

Can someone give me some pointers to some good tutorial, text,  
documentation? I know about multiprogramming, but I never did anything  
in a kernel.

Thank,
Nikola
