Enabling Numa

[fahadshery]

Hi,

I was looking at the docs about enabling NUMA because I have dual Xeon E5-2650 v2 processors on a dell R720 server. I have searched everywhere to find a good guide to enable NUMA according to the number of nodes and sockets.
Anyone has tried it and could help?

Cheers,

hi,

what do you get from numactl --hardware?

I have searched everywhere to find a good guide to enable NUMA according to the number of nodes and sockets.

notice the following from the numa wiki link:

As a rule of thumb your system is NUMA-aware if you have more than one CPU.

to enable numa for a VM you just need to tick the box in the menu VM -> Hardware -> Processor -> Enable NUMA

Thank you for your reply. I was thinking the process would be very complicated but it was just a tick box in the `CPU` section

Needless to say but I changed all my VMs to NUMA and My windows 10 VM with a GPU passthrough is successfully giving above 60fps to AppleTV via Moonlight app which was dreadful without NUMA!
I have tried games such as Dead & Cells, Monster trucks, Hitman and GTA V! I am sure this could be further improved if I run an Ethernet Cable from the router to the AppleTV but for now it's just ok for casual gaming

This is what I get:

root@pve:~# numactl --hardware
available: 2 nodes (0-1)
node 0 cpus: 0 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30
node 0 size: 80525 MB
node 0 free: 904 MB
node 1 cpus: 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31
node 1 size: 112854 MB
node 1 free: 385 MB
node distances:
node   0   1
  0:  10  20
  1:  20  10

I have about 5 VMs and the Server is Dell R720 with dual E5-2650 v2, 2 x nVidia GPUs and 192GB RAM
