Question on CPU CpuAffinity

[Manny 1,293]

This is the default:

; selects the CPU running the trainer process: 1 to 32
; 0: last core, -1: automatic.
CpuAffinity = -1

 

Its not clear

CpuAffinity = 0 means use the last core?

and CpuAffinity = -1 means automatic?

What is 1 to 32?

I want to avoid using the  the process 0 and 1. for a 4 core processor with HT. so 4 X 2 = 8 thread

what should be my parameter?

 

I have it as CpuAffinity = 0

Well, if it's not automatic (-1), and if it's not last core (0), then it is the CPU running the trainer process: 1 to 32

If you have 4 cores, you can select from 1 to 4. Once you have the Intel SuperCore 32 (forward prediction), you can select from 1 to 32 ;-)

Honestly, unless you have a particular issue, you rather leave it to automatic. It will make sure your GNS #1 and GNS #2 won't walk on their respective toes, and will leave your simulator cores alone.
