There are also NUMA nodes which, amongst others,
the Linux kernel uses. For AMD systems these
essentially map onto sockets.
For example on a dual socket, quad core Barcelona:
[root at tango001 node]# pwd
[root at tango001 node]# ls -F
has_cpu has_normal_memory node0/ node1/ online possible
[root at tango001 node]# cd node1
[root at tango001 node1]# ls
cpu4 cpu6 cpulist distance numastat
cpu5 cpu7 cpumap meminfo scan_unevictable_pages
[root at tango001 node1]# cat distance
