Just to be clear:

Imagine a 2 socket box with dual core hyperthreaded Xeons:

cpu# thread core socket
0       0       0       0
1       1       0       0
2       0       1       0
3       1       1       0
4       0       0       1
5       1       0       1
6       0       1       1
7       1       1       1

Best,
Ian
