Detailed Description
Function Documentation
   static inline int hwloc_cudart_get_device_cpuset (hwloc_topology_t topology, intidx, hwloc_cpuset_tset) [static]
       Get the CPU set of logical processors that are physically close to device idx. Return the CPU set describing the locality of the CUDA
       device whose index is idx.

       Topology topology and device idx must match the local machine. I/O devices detection and the CUDA component are 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_cudart_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 inline hwloc_obj_t hwloc_cudart_get_device_osdev_by_index (hwloc_topology_ttopology, unsignedidx) [static]
       Get the hwloc OS device object corresponding to the CUDA device whose index is idx. Return the OS device object describing the CUDA 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 and the CUDA component must be enabled in the topology. If not, the locality of the object may still be found
       using hwloc_cudart_get_device_cpuset().

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

	   This function is identical to hwloc_cuda_get_device_osdev_by_index().

   static inline int hwloc_cudart_get_device_pci_ids (hwloc_topology_t topology, intidx, int *domain, int *bus, int *dev) [static]
       Return the domain, bus and device IDs of the CUDA device whose index is idx. Device index idx must match the local machine.

   static inline hwloc_obj_t hwloc_cudart_get_device_pcidev (hwloc_topology_ttopology, intidx) [static]
       Get the hwloc PCI device object corresponding to the CUDA device whose index is idx. Return the PCI device object describing the CUDA
       device whose index is idx. Return NULL if there is none.

       Topology topology and device idx must match the local machine. I/O devices detection must be enabled in topology topology. The CUDA
       component is not needed in the topology.
