Hardware Locality (hwloc)                        Version 2.12.0                        hwlocality_openfabrics(3)

       This interface offers ways to retrieve topology information about OpenFabrics devices (InfiniBand, Omni-
       Path, usNIC, etc).

inthwloc_ibv_get_device_cpuset(hwloc_topology_ttopology,structibv_device*ibdev,hwloc_cpuset_tset)[inline]
       Get the CPU set of processors that are physically close to device ibdev. Store in set the CPU-set
       describing the locality of the OpenFabrics device ibdev (InfiniBand, etc).

       Topology topology and device ibdev must match the local machine. I/O devices detection is not needed in
       the topology.

       The function only returns the locality of the device. If more information about the device is needed, OS
       objects should be used instead, see hwloc_ibv_get_device_osdev() and
       hwloc_ibv_get_device_osdev_by_name().

       This function is currently only implemented in a meaningful way for Linux; other systems will simply get
       a full cpuset.

       Returns
           0 on success.

           -1 on error, for instance if device information could not be found.

   hwloc_obj_thwloc_ibv_get_device_osdev(hwloc_topology_ttopology,structibv_device*ibdev)[inline]
       Get the hwloc OS device object corresponding to the OpenFabrics device ibdev.

       Returns
           The hwloc OS device object describing the OpenFabrics device ibdev (InfiniBand, etc).

           NULL if none could be found.

       Topology topology and device ibdev must match the local machine. I/O devices detection must be enabled in
       the topology. If not, the locality of the object may still be found using hwloc_ibv_get_device_cpuset().

       Note
           The corresponding PCI device object can be obtained by looking at the OS device parent object.

   hwloc_obj_thwloc_ibv_get_device_osdev_by_name(hwloc_topology_ttopology,constchar*ibname)[inline]
       Get the hwloc OS device object corresponding to the OpenFabrics device named ibname.

       Returns
           The hwloc OS device object describing the OpenFabrics device (InfiniBand, Omni-Path, usNIC, etc)
           whose name is ibname (mlx5_0, hfi1_0, usnic_0, qib0, etc).

           NULL if none could be found.

       The name ibname is usually obtained from ibv_get_device_name().

       The topology topology does not necessarily have to match the current machine. For instance the topology
       may be an XML import of a remote host. I/O devices detection must be enabled in the topology.

       Note
           The corresponding PCI device object can be obtained by looking at the OS device parent object.
