[Windows] Strange behavior of Process.cpu_affinity on a 2-nodes system.

[RyougiKukoc]

Summary

• OS: Windows10
• Architecture: 64bit
• Psutil version: 5.9.5
• Python version: 3.11.1
• Type: core

Description

Working on a Intel Xeon Platinum 8175M * 2 machine, (24c 48t)*2. psutil.cpu_count() returns 96.

I want to specify the process working on different nodes, but when I set psutil.Process().cpu_affinity([48]), a strange behavior occurs as shown below.

In _pswindows.py, 48 is in the list of allcpus, so it accepts the id and passes to proc_cpu_affinity_set, and goes wrong.

So I think whether it is an unwanted behavior of proc_cpu_affinity_set on server that has multiple cpu sockets, or allcpus should be corrected and 48 in this case should be raise by a ValueError: Invalid CPU 48.

What's the translation of those Chinese (or Japanese?) characters?
