Detailed Description

Function Documentation

hwloc_cpuset_from_nodeset()

static int hwloc_cpuset_from_nodeset ( hwloc_topology_t  topology, hwloc_cpuset_t  _cpuset, hwloc_const_nodeset_t  nodeset  )

inlinestatic

Convert a NUMA node set into a CPU set and handle non-NUMA cases.

If the topology contains no NUMA nodes, the machine is considered as a single memory node, and the following behavior is used: If nodeset is empty, cpuset will be emptied as well. Otherwise cpuset will be entirely filled. This is useful for manipulating memory binding sets.

hwloc_cpuset_to_nodeset()

static int hwloc_cpuset_to_nodeset ( hwloc_topology_t  topology, hwloc_const_cpuset_t  _cpuset, hwloc_nodeset_t  nodeset  )

inlinestatic

Convert a CPU set into a NUMA node set and handle non-NUMA cases.

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.

If the topology contains no NUMA nodes, the machine is considered as a single memory node, and the following behavior is used: If cpuset is empty, nodeset will be emptied as well. Otherwise nodeset will be entirely filled.
