Hi,

Sorry for this dumb question, but I feel a bit confused. As far as I understood all Zen2 like CPU's are NUMA based, so in case of AMD Ryzen, Epyc, etc, they all have "numa support".

When creating a new VM, Proxmox allows me to select up to 4 Sockets (which again indicates NUMA support). However, checking the documentation:

if the command numactl --hardware | grep available returns more than one node, then your host system has a NUMA architecture

The command only returns:

Bash:
# numactl --hardware | grep available
available: 1 nodes (0)

So... does this CPU support NUMA in Proxmox or not?

Please advise...
 
The 5600x only got one chiplet and Ryzen 5000 doesn't support multiple sockets, so using NUMA shouldn`t be beneficial.
