Change numa group in running process via PowerShell - powershell

Question

I would like to change numa group in running process via PS
all the time is take group 1 :( and cpu work 50%
this - I can do by hand but I don`t know how via PS
my problem is that I have processes that always get assigned to the same group, resulting in 50% of the cpu
Mathias when I add 2 I get this (in the powershell instruction the bitmask controlls number of cpus to in a processor group only - so if the process get's assigned to a group 0, the instruction only changes the number of cpus in this group)

Answer 1

This is not what I call an answer actually (I am not a C++ dev), however, here is a part of the way to probably achieve this :
$MethodDefinition = #'
[DllImport("kernel32.dll", CharSet = CharSet.Unicode, SetLastError = true)]
public static extern bool SetThreadGroupAffinity(......);
'#
$Kernel32 = Add-Type -MemberDefinition $MethodDefinition -Name "Kernel32" -PassThru
#Retrieve the Thread handle first
#Call by $Kernel32::SetThreadGroupAffinity(......)
MS docs SetThreadGroupAffinity,
MS docs GoupAfffinity Structure
May be this one be useful too MS docs SetThreadAffinityMask

Answer 2

You need to set the ProcessorAffinity property on the corresponding process:
Get-Process vmmem |ForEach-Object {
$_.ProcessorAffinity = [IntPtr]::new([long]-1) # -1 corresponds to all 64 bits set
}
