CHR: number of CPUs limited to 64?

Thu Oct 29, 2020 4:07 pm


I have dual socket server with two AMD Epyc 7742 processors, so it has 128 physical cores available with HT disabled. I`m running Proxmox 6.2-12 on it with just one VM with Mikrotik CHR (6.47.7). The problem is that I can`t see more than 64 CPUs in CHR. Is it some reasonable limit with the number of CPUs? For example CCR1072 has 72 cores...

Thank you

So each socket has 64 cores and each CPU is it's on NUMA node if my memory is correct. So if you want to use more then 64 cores you have to use more then one socket.

How have you configured CPU on the VM the CHR is running on?
