SYNOPSIS

   Functions
       static int hwloc_intel_mic_get_device_cpuset (hwloc_topology_t topology, int idx,
           hwloc_cpuset_t set)
       static hwloc_obj_t hwloc_intel_mic_get_device_osdev_by_index (hwloc_topology_t topology,
           unsigned idx)

Detailed Description

       This interface offers ways to retrieve topology information about Intel Xeon Phi (MIC)
       devices.

Function Documentation

   static int hwloc_intel_mic_get_device_cpuset (hwloc_topology_t topology, int idx,
       hwloc_cpuset_t set) [inline],  [static]
       Get the CPU set of logical processors that are physically close to MIC device whose index
       is idx. Return the CPU set describing the locality of the MIC device whose index is idx.

       Topology topology and device index idx 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_intel_mic_get_device_osdev_by_index().

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

   static hwloc_obj_t hwloc_intel_mic_get_device_osdev_by_index (hwloc_topology_t topology,
       unsigned idx) [inline],  [static]
       Get the hwloc OS device object corresponding to the MIC device for the given index. Return
       the OS device object describing the MIC device whose index is idx. Return NULL if there is
       none.

       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.
