How do I enable all cores on dual CPU using both Group 0 and 1.

[weddings]

Hi Team,

I am using dual xeon cpu with 36 cores each. I am trying to enable all CPU affinity on all 72 cores however it seems I can only choose "Group 0" or "Group 1" under Processor Group on the top right of the menu. Is there any way to choose both Groups 0 and 1 so I can enable all 72 cores?

Affinity bitmask (Hex) for:

"Any" is  "FFFFFFFFF"
"Group 0" "0/FFFFFFFFF"
"Group 1" "1/FFFFFFFFF"

Maybe I am able to type something in the Affinity bitmask (Hex) to enable both Groups?

I have attached some screenshots. Appreciate any assistance thanks!

Windows CPU affinities don't support multiple processor groups, which is why you can't create one. You can use CPU Sets for that.

However, I do not believe either will accomplish what you want. Is your application constrained to one of the two processor groups, and you are trying to force it to use the other processor group? Sometimes this can be addressed with the Processor Group Extender feature. Give it a try and let me know how it goes!
