Detailed Description

Function Documentation

inthwloc_cpuset_from_nodeset(hwloc_topology_ttopology,hwloc_cpuset_t_cpuset,hwloc_const_nodeset_tnodeset)[inline]
       Convert a NUMA node set into a CPU set. For each NUMA node included in the input nodeset, set the
       corresponding local PUs in the output _cpuset.

       If some CPUs have no local NUMA nodes, this function never sets their indexes in the output CPU set, even
       if a full node set is given in input.

       Hence the entire topology node set is converted into the set of all CPUs that have some local NUMA nodes.

       Returns
           0 on success.

           -1 with errno set to ENOMEM on internal reallocation failure.

   inthwloc_cpuset_to_nodeset(hwloc_topology_ttopology,hwloc_const_cpuset_t_cpuset,hwloc_nodeset_tnodeset)[inline]
       Convert a CPU set into a NUMA node set. For each PU included in the input _cpuset, set the corresponding
       local NUMA node(s) in the output nodeset.

       If some NUMA nodes have no CPUs at all, this function never sets their indexes in the output node set,
       even if a full CPU set is given in input.

       Hence the entire topology CPU set is converted into the set of all nodes that have some local CPUs.

       Returns
           0 on success.

           -1 with errno set to ENOMEM on internal reallocation failure.
