Different "length" to memory on the same doamin?

Just a question:
If you have for example an 8-way Opteron system, then each processor has it's own memory. If a processor wants some data which is in an other processors memory, it has to go through the other processors. But the Opterons are connected in some sort of a ring, so sometimes the data may be just one neighbour away, and sometimes it must go through 2 ( or maybe even more?) processors to get it's data.
For me it looks like all these eight processors are on the same scheduling domain, even though some are "more close" to each other than others?
How does the scheduling domains system handel this?
