```
The intention of the changes is clearly highlighted the NUMA divisioning and CPU pinning within single or multiple sockets. But as pointed out @Dmitry Kozlyuk if the end user will use hwloc on both linux & windows to identify these, we should promote and document the changes provided the existing tool is phased out.
Note: there were questions asked in forums, stackoverflow and github on NUMA to CPU pinning, hence enhanced the tool to accommodate the changes.
