Binding CPUs to NUMA NodesOn systems with a NUMA (Non-Uniform Memory Access) architecture, you can configure Containers to use CPUs from specific NUMA nodes only. Let us assume the following:
To set Container 101 to use the processors from NUMA node 1, run the following command: # prlctl set 101 --nodemask 1 To check that Container 101 is now bound to NUMA node 1, use this command: # vzlist 101 -o nodemask NODEMASK 1 To unbind Container 101 from NUMA node 1, execute this command: # prlctl set 101 --nodemask all Now Container 101 should be able to use all CPUs on the server again.
