Does the system label an entire CPU at a time? So 0-5 would be CPU#0 and 6-11 would be CPU#1?
Or does it stripe them? So all even numbers are CPU#0 and odd numbers are CPU#1?
AFAIK, VMware does not perform any specific labelling or grouping of logical cpus. It is the feature of the cpu vendor and the bios to show case the
- number of sockets available
- number of cores and number of logical cpus that are available on the cores.
ESX just gets this information from it and displays to the client.
