NAME

       hwlocality_helper_distribute - Distributing items over a topology

SYNOPSIS

   Enumerations
       enum hwloc_distrib_flags_e { HWLOC_DISTRIB_FLAG_REVERSE }

   Functions
       static int hwloc_distrib (hwloc_topology_t topology, hwloc_obj_t *roots, unsigned n_roots,
           hwloc_cpuset_t *set, unsigned n, int until, unsigned long flags)

Detailed Description

Enumeration Type Documentation

   enum hwloc_distrib_flags_e
       Flags to be given to hwloc_distrib().

       Enumerator

       HWLOC_DISTRIB_FLAG_REVERSE
              Distrib in reverse order, starting from the last objects.

Function Documentation

   static int hwloc_distrib (hwloc_topology_t topology, hwloc_obj_t * roots, unsigned n_roots,
       hwloc_cpuset_t * set, unsigned n, int until, unsigned long flags) [inline],  [static]
       Distribute n items over the topology under roots. Array set will be filled with n cpusets
       recursively distributed linearly over the topology under objects roots, down to depth
       until (which can be INT_MAX to distribute down to the finest level).

       n_roots is usually 1 and roots only contains the topology root object so as to distribute
       over the entire topology.

       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.

       flags should be 0 or a OR'ed set of hwloc_distrib_flags_e.

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