 Distribute n items over the topology under root.

Function Documentation

static inline void hwloc_distribute ( hwloc_topology_t  topology,
hwloc_obj_t  root,
hwloc_cpuset_t cpuset,
int  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 typicall want to additionally call hwloc_cpuset_singlify() before binding a thread, so that it doesn't move at all.
