Detailed Description

Function Documentation

static inline int hwloc_cudart_get_device_cpuset ( hwloc_topology_t topology  , int  device, hwloc_cpuset_t  set  )

static

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.
