In addition, you might want to upgrade to Open MPI 1.6.x -- 1.4.x is fairly
ancient. 1.6.x's mpirun also has a --report-bindings option which tells you
where procs are bound. For example:
mpirun --bind-to-core --report-bindings ...etc.

IntelMPI binds processes by default, while OMPI doesn't. What's your
mpiexec/mpirun command-line?

Hello Sir
Here below is the code which I wrote using hwloc for getting the bindings
of the processes.
I tested this code on SDSC Gordon Super Computer which has Open MPI 1.4.3
and on TACC Stampede which uses intel's MPI library IMPI.
With Open MPI I get all the core ids for all the processes as 0.
