Hello,
I'm reading about NUMA, and i've read numa_maps in proc of some process,
why the kernel uses only one node?

Because you only have one node to use?

What does `ls -l /sys/devices/system/node | wc -l` say?

# cat /proc/self/numa_maps
00400000 default file=/bin/cat mapped=3 N0=3

every process has always N0, that mean node 0
I'm on amd turion64 X2, then I've dual core.


Nodes != Processors. You can have many processors on a node all
sharing the same memory.

The unique node is not used only in x86 arch?

I can't parse this question.

Thanks,
Nish
