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.
