static inline void hwloc_distribute	(	hwloc_topology_t	topology,
		hwloc_obj_t	root,
		hwloc_cpuset_t *	cpuset,
		unsigned	n
	)			[static]

Distribute n items over the topology under root.

Array cpuset will be filled with n cpusets distributed linearly over the topology under root .

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_cpuset_singlify() before binding a thread so that it does not move at all.
