with HWLOC_MEMBIND_BIND is useless?
It's likely the most useful memory binding case. It's similar to
what numactl --membind does for instance, very common.
The behaviour I want to set is it possible?
I just said "you have to touch right after malloc."

policy, it's allocated according to the policy of the thread
touches, not according to the policy of the one that did
malloc. If you
want to follow the malloc'er thread, you have to touch right
