Numa_distance processor support

[Multipath]

Which Intel processors are internally divided into nodes.  When I call numa_distance I only get 1 node.  On a AMD EPIC 64 core processor, I get 8x8 nodes.

Hello Multipath,

Greetings!

Thank you for posting in Intel community Forum. Based on your inquiry, we see that you wish to know which Intel processors are internally divided into nodes and when you call numa_distance, you are only getting 1 node.

Kindly provide us the processor model details for which you are running this so that we can check this for you.

We have a commercial software product which runs on all Intel processors.  I was hoping for a generic answer.  From what we have been able to determine:

1. Processors with 9 or fewer cores have a single memory controller (numa_distance=1)

2. Processors with 10 or more controllers have 2 memory controllers (numa_distance=1 or 2)

3. Systems with multiple sockets will have  numa_distance 2 or more.

4. Memory controllers can interleave memory access.  For best performance have 2 memory chips per memory controller.

Is this correct?
