Get the CPU set of logical processors that are physically close to device
For the given CUDA Driver API device
cudevice, read the corresponding kernel-provided cpumap file and return the corresponding CPU set. This function is currently only implemented in a meaningful way for Linux; other systems will simply get a full cpuset.
topology must match the current machine.
Return the domain, bus and device IDs of device
Get the hwloc object for the PCI device corresponding to device
For the given CUDA Runtime API device
cudevice, return the hwloc PCI object containing the device. Returns NULL if there is none.
IO devices detection must be enabled in topology
