NAME
hwlocality_intel_mic - Interoperability with Intel Xeon Phi (MIC)
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.
