Yes, but only a bit, better is to ask those questions on the smp mailing list or to visit the web server which contains some words to the current and future SMP implementation and a list of mainboards that are known to work. > Background: I am currently doing graduate studies at the University > of Ottawa (Canada).

I just trying to figure out how the > jobs are administrate on a dual cpu systems. One task runs on one CPU. I'd compare it with early SMP like in Suns Solaris 1.
