Function Documentation

static inline hwloc_cpuset_t hwloc_ibv_get_device_cpuset ( struct ibv_device *  ibdev  )  [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.
