Detailed Description

Function Documentation

hwloc_topology_get_allowed_cpuset()

static hwloc_const_cpuset_t hwloc_topology_get_allowed_cpuset ( hwloc_topology_t  topology )

inlinestatic

Get allowed CPU set.

Returns

the CPU set of allowed logical processors of the system. If the topology is the result of a combination of several systems, NULL is returned.

Note

The returned cpuset is not newly allocated and should thus not be changed or freed, hwloc_bitmap_dup() must be used to obtain a local copy.

hwloc_topology_get_allowed_nodeset()

static hwloc_const_nodeset_t hwloc_topology_get_allowed_nodeset ( hwloc_topology_t  topology )

inlinestatic

Get allowed node set.

Returns

the node set of allowed memory of the system. If the topology is the result of a combination of several systems, NULL is returned.

Note

The returned nodeset is not newly allocated and should thus not be changed or freed, hwloc_bitmap_dup() must be used to obtain a local copy.

hwloc_topology_get_complete_cpuset()

static hwloc_const_cpuset_t hwloc_topology_get_complete_cpuset ( hwloc_topology_t  topology )

inlinestatic

Get complete CPU set.

Returns

the complete CPU set of logical processors of the system. If the topology is the result of a combination of several systems, NULL is returned.

Note

The returned cpuset is not newly allocated and should thus not be changed or freed; hwloc_bitmap_dup() must be used to obtain a local copy.

hwloc_topology_get_complete_nodeset()

static hwloc_const_nodeset_t hwloc_topology_get_complete_nodeset ( hwloc_topology_t  topology )

inlinestatic

Get complete node set.

Returns

the complete node set of memory of the system. If the topology is the result of a combination of several systems, NULL is returned.

Note

The returned nodeset is not newly allocated and should thus not be changed or freed; hwloc_bitmap_dup() must be used to obtain a local copy.

hwloc_topology_get_online_cpuset()

static hwloc_const_cpuset_t hwloc_topology_get_online_cpuset ( hwloc_topology_t  topology )

inlinestatic

Get online CPU set.

Returns

the CPU set of online logical processors of the system. If the topology is the result of a combination of several systems, NULL is returned.

Note

The returned cpuset is not newly allocated and should thus not be changed or freed; hwloc_bitmap_dup() must be used to obtain a local copy.

hwloc_topology_get_topology_cpuset()

static hwloc_const_cpuset_t hwloc_topology_get_topology_cpuset ( hwloc_topology_t  topology )

inlinestatic

Get topology CPU set.

Returns

the CPU set of logical processors of the system for which hwloc provides topology information. This is equivalent to the cpuset of the system object. If the topology is the result of a combination of several systems, NULL is returned.

Note

The returned cpuset is not newly allocated and should thus not be changed or freed; hwloc_bitmap_dup() must be used to obtain a local copy.

hwloc_topology_get_topology_nodeset()

static hwloc_const_nodeset_t hwloc_topology_get_topology_nodeset ( hwloc_topology_t  topology )

inlinestatic

Get topology node set.

Returns

the node set of memory of the system for which hwloc provides topology information. This is equivalent to the nodeset of the system object. If the topology is the result of a combination of several systems, NULL is returned.

Note

The returned nodeset is not newly allocated and should thus not be changed or freed; hwloc_bitmap_dup() must be used to obtain a local copy.
