Sorry Thomas, I did not follow your ` I don't understand why we continue working on this script. I thought we agreed it should be removed in favor of lstopo.`

From last email from my end `we should promote and document the changes provided the existing tool is phased out and use lstopo`.

Note:
1. This is with assumption that both Linux and Windows `lstopo` is modified and handles `ACPI L3 SRAT NUMA` and `Node per Socket NUMA`.
2. I have not seen a depreciation notice for cpu_layout.py too.
