The request should never ask for "NUMA Node 0". The reason is because the request shouldn't require that the user understand where the resources are.
It shouldn't matter *which* NUMA node a particular device that is providing some resources is affined to. The only thing that matters to a *request* is that the user is able to describe the nature of the affinity.
Yes, very much yes to these two paragraphs. See also: http://lists.openstack.org/pipermail/openstack-discuss/2019-April/005682.htm...
I propose using a "group_policy=same_tree:$GROUP_A:$GROUP_B" query parameter for enabling users to describe the affinity constraints for various resources involved in different RequestGroups in the request spec.
At first glance this seems pretty reasonable. Does anyone hate it? -- Chris Dent ٩◔̯◔۶ https://anticdent.org/ freenode: cdent tw: @anticdent
