Constant hwloc::MEMBIND_FIRSTTOUCH

pub const MEMBIND_FIRSTTOUCH: MemBindPolicy = MemBindPolicy{bits: 1,}

Allocate memory but do not immediately bind it to a specific locality. Instead, each page in the allocation is bound only when it is first touched. Pages are individually bound to the local NUMA node of the first thread that touches it. If there is not enough memory on the node, allocation may be done in the specified cpuset before allocating on other nodes.
