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.
