Better multiprocessor support in 10.1?

Hi, I have 9.2 and was told by a tech as Suse that 10.1 would be better suited for machines with multiple processors (my IBM has dual 248 Opterons, 8 gigs of ram). Can anyone help me understand how this will impact me? I do number crunching with matlab. I'd like to run two matlabs at once (it is not multi threaded). Thanks Jim
