Gigantic hugepages are allocated by the hypervisor (not the Linux VM), and we don't control where the allocation occurs. Yes, ideally, they would be interleaved to avoid this situation, but I can also see reasons for having them all be from one node so that tasks can be affinitized and get the guarantee of the 16GB pagesize benefit.
