In a linux(CentOS)/multiprocessor setting, how to assign CPU cores to NUMA nodes? -


i working on quad operton 6272 system centos installed on it. suspect there wrong numa configuration.

when run numactl --hardware get:

available: 5 nodes (0,2-4,6) node 0 cpus: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 node 0 size: 32765 mb node 0 free: 31145 mb node 2 cpus: 16 17 18 19 20 21 22 23 node 2 size: 16384 mb node 2 free: 15501 mb node 3 cpus: 24 25 26 27 28 29 30 31 40 41 42 43 44 45 46 47 node 3 size: 16384 mb node 3 free: 14913 mb node 4 cpus: 32 33 34 35 36 37 38 39 node 4 size: 32768 mb node 4 free: 31551 mb node 6 cpus: 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 node 6 size: 32752 mb node 6 free: 31575 mb node distances: node   0   2   3   4   6    0:  10  16  22  16  16    2:  16  10  16  16  16    3:  22  16  10  22  22    4:  16  16  22  10  16    6:  16  16  22  16  10

there 4 cpu chips having 5 numa nodes makes no sense me.

can please tell me cpu cores assigned numa nodes?

do have kernel boot options defined memory layout? can post dmesg boot numa nodes listed memory ranges? also, nice know kernel version , libnuma version.
