Hi,

That is assuming you have 2-link cpu's. AMD64 cpu's have 3 links, so 4 would be optimal (iirc that is - you could use one link per cpu for something else, after which 3 would be better). What's this doing in OS design & theory?
At least one link in one CPU needs to be used for I/O...
Code:
B-A-IO

Communication between CPU #A and CPU #C involves 2 hops. Latest rumours say the newest AMD CPUs will have 4 HT links, but you won't be able to use all of those links until AMD introduce a new socket (not enough pins on the corrent socket).
