For Opterons where each node has its own RAM this is a little bit more
complex, right?

I was wondering how you make the APs not conflict in the part of RAM they
copy their buffers to.  I was also wondering how it would affect
interleaving, etc.  That kind of thing seems difficult to debug, and is the
reason I'd want to see the APs messages.
