There is indeed something odd with what the Linux kernel reports:
os node 1 has cpuset 0x0003ffff
os node 2 has cpuset 0x00fc0000
as can be seen in /sys/devices/system/node/node*/cpumap, but
os socket 0 has cpuset 0x00000fff
os socket 1 has cpuset 0x00fff000
as can be seen in /sys/devices/system/cpu/cpu*/topology/physical_package_id
i.e. the kernel reports that socket 0 is completely in node 1, while
socket 1 is half in node 1 and half in node 2. Do you have more
information about what the machine actually contains socket- and
NUMA-wise? The dell website is not really felpful, it talks about 4-16
cores for the DL165 G7, while you have 24.
