Allocate some memory on the memory nodes near given cpuset cpuset.
This is similar to hwloc_alloc_membind_policy_nodeset, but for a given cpuset.
Allocate some memory on the given nodeset nodeset.
This is similar to hwloc_alloc_membind except that it is allowed to change the current memory binding policy, thus providing more binding support, at the expense of changing the current state.
Distribute n items over the topology under root.
Distribute n items over the topology under roots.
Array cpuset will be filled with n cpusets recursively distributed linearly over the topology under root, down to depth until (which can be INT_MAX to distribute down to the finest level).
This is typically useful when an application wants to distribute n threads over a machine, giving each of them as much private cache as possible and keeping them locally in number order.
The caller may typically want to also call hwloc_bitmap_singlify() before binding a thread so that it does not move at all.
This is the same as hwloc_distribute, but takes an array of roots instead of just one root.
