Detailed Description

Function Documentation

   static inline void hwloc_distribute (hwloc_topology_ttopology, hwloc_obj_troot, hwloc_cpuset_t
       *set, unsignedn, unsigneduntil) [static]
   static inline void hwloc_distributev (hwloc_topology_ttopology, hwloc_obj_t *roots,
       unsignedn_roots, hwloc_cpuset_t *set, unsignedn, unsigneduntil) [static]
       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.

       Note:
           This function requires the root object to have a CPU set.

       This is the same as hwloc_distribute, but takes an array of roots instead of just one
       root.

       Note:
           This function requires the roots objects to have a CPU set.
