566 | * | |
567 | * However for CLI convenience it's possible to pass in subset of properties, | |

573 | * will assign all child cores of socket 0 to node 0 and | |
574 | * of socket 1 to node 1. | |
575 | * | |
576 | * On attempt of reassigning (already assigned) cpu slot to another NUMA node, | |
