hwlocality_intel_mic(3)	   Hardware Locality (hwloc)   hwlocality_intel_mic(3)

NAME
       hwlocality_intel_mic

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.
