hwloc_distribute3

static inline void* hwloc_alloc_membind_policy (hwloc_topology_ttopology, size_tlen, hwloc_const_cpuset_tcpuset, hwloc_membind_policy_tpolicy, intflags) [static]

Allocate some memory on the memory nodes near given cpuset cpuset. This is similar to hwloc_alloc_membind_policy_nodeset, but for a given cpuset.

static inline void* hwloc_alloc_membind_policy_nodeset (hwloc_topology_ttopology, size_tlen, hwloc_const_nodeset_tnodeset, hwloc_membind_policy_tpolicy, intflags) [static]

Allocate some memory on the given nodeset nodeset. This is similar to hwloc_alloc_membind except that it is allowed to change the current memory binding policy, thus providing more binding support, at the expense of changing the current state.

static inline void hwloc_distribute (hwloc_topology_ttopology, hwloc_obj_troot, hwloc_cpuset_t *cpuset, unsignedn, unsigneduntil) [static]

static inline void hwloc_distributev (hwloc_topology_ttopology, hwloc_obj_t *roots, unsignedn_roots, hwloc_cpuset_t *cpuset, 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 is the same as hwloc_distribute, but takes an array of roots instead of just one root.
