Get the CPU set of logical processors that are physically close to device cudevice
.
For the given CUDA Runtime 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.
