help with the output of numactl (NUMA)

[Stanley Guan]

Hi,

How to interpret the outputs of numactl?

$ numactl --hardware
available: 1 nodes (0-0)
node 0 size: 32284 MB
node 0 free: 12941 MB
node distances:
node   0
   0:  10


$ numactl --show
policy: default
preferred node: current
physcpubind: 0 1 2 3 4 5 6 7
cpubind: 0
nodebind: 0
membind: 0

Specifically,

1. What's the default policy?  Is it localalloc?
2. Our system has 8 cpu's and 1 node (?).  Is this one memory node?
3. What does "10" mean in "0: 10"?

Thanks,

-Stanley
