Hi,
I'm aware of the ability to use the memory controller to limit how much memory a
group of tasks can consume.
Is there any way to limit how much memory a group of tasks can consume *per NUMA
node*?
The specific scenario I'm considering is that of a hypervisor host. I have
system management stuff running on the host that may need more than one core,
and currently these host tasks might be affined to cores from multiple NUMA
nodes. I'd like to put a cap on how much memory the host tasks can allocate
from each NUMA node in order to ensure that there is a guaranteed amount of
memory available for VMs on each NUMA node.
Is this possible, or are the knobs just not there?
Thanks,
Chris
