Brice Sir's explanation of what I want is correct.
Your last reply was asking me to look for ompi_proc_t for the process in the proc_flafs field if I am correct. You said that the defintion of the values will be in opal/mca/hwloc/hwloc.h. I checked in this file in OpenMPI 1.6. I couldn't find it. Is it available in the later versions of OpenMPI.
The locality of every process is stored on the ompi_proc_t for that process in the proc_flags field. You can find the definition of the values in opal/mca/hwloc/hwloc.h.
