Intel is more recent to this game. I believe AMD's last non-NUMA machines where the Athalon XP series and Intel's the Core 2 series.
An easy way to see what you've got is to see what 'numactl --hardware' says.
Ah, thanks. I trust this one qualifies? $ numactl --hardware available: 4 nodes (0-3) node 0 cpus: 0 4 8 12 16 20 24 28 node 0 size: 16370 MB node 0 free: 14185 MB node 1 cpus: 1 5 9 13 17 21 25 29 node 1 size: 16384 MB node 1 free: 10071 MB node 2 cpus: 2 6 10 14 18 22 26 30 node 2 size: 16384 MB node 2 free: 14525 MB node 3 cpus: 3 7 11 15 19 23 27 31 node 3 size: 16384 MB node 3 free: 13598 MB node distances: node 0 1 2 3 0: 10 20 20 20 1: 20 10 20 20 2: 20 20 10 20 3: 20 20 20 10 /proc/cpuinfo says there 32 "Intel(R) Xeon(R) CPU E7- 4830" CPUs.
