Stefan, So the values of the array depend on the links of cpu to cpu?
yes, indeed.
If I got an example : Link0 of CPU0 to Link1 of CPU1 Link1 of CPU0 to Link0 of CPU3 Link0 of CPU1 to Link0 of CPU2 Link2 of CPU2 to Link1 of CPU3
what are the values of the array? I hope I can realize from some examples...

Check chapter 3.3.6: "Routing Table Node i Registers"
But note: since the topology is nowadays detected automatically, you don't need to care anyways...
BTW, I search the keyword "AMD K8 BKDG(or AMD K8 BGDG)" in google, it has a little information, could you tell where can get more infromations? Thanks....
Sorry,.. I was starting to use LinuxBIOS slang. The full name is "BIOS and Kernel Developer's Guide for AMD Athlon(tm)64 and AMD Opteron(tm) Processors".. BKDG is just so much quicker to write ;))
