It's up to the operating system kernel to spread the load on all CPUs
(or CPU cores); e.g. if you run "lilypond -djob-count=2" and you have no
other processor time-consuming tasks at the same time (if this can ever
happen on Vista :-P) on a dual core CPU, the kernel should spread each
lilypond process on one different core. The reality may be a bit more
complex, but this is roughly the principle.
It may be possible to parallelize some portions of LilyPond code to take
advantage of multi-core machines, which gradually become quite common,
I'm tempted to have a look at it in the next months, but don't hold your
breath :-)
Cheers,
John
