The only thing that changes is the required connectivity. It sounds to me like you may have a firewall issue here, where cloud3 is blocking connectivity from cloud6, but cloud6 is allowing connectivity from cloud3.
Is there a firewall in operation, per chance?

You are both correct. If you simply type "mpirun pvserver", then we will execute pvserver on whatever machine is local.
However, if you type "mpirun -n 1 -H host1 pvserver", then we will start pvserver on the specified host. Note that mpirun will still be executing on your local machine - but pvserver will be running on the specified host.
Does anything change based on where mpirun is executing?
Can you shed any light on the initial question of asymmetric behavior?
