If the operating system orders the CPUs differently relative to the ldom/socket, this
mapping has different results. In the above example, the CPU ID must be referenced
to the physical ID from the /proc/cpuinfo file to verify which socket the ranks
landed on.
To see the default binding order and ldom/Socket/CPU placement information, use the
default_cpu,v option with -cpu_bind:
% mpirun -cpu_bind=default_cpu,v -np 8 hello_world.exe
