static __hwloc_inline int hwloc_ibv_get_device_cpuset ( hwloc_topology_t topology  __hwloc_attribute_unused,
struct ibv_device *  ibdev,
hwloc_cpuset_t  set 
) [static]

Get the CPU set of logical processors that are physically close to device ibdev.

For the given OpenFabrics device ibdev, 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.
