Sure, the machines can be specified as argument to `mpiexec`. But do you want to run applications just between these two machines, or should they participate on a larger parallel job with machines of the cluster: then a direct network connection between outside and inside of the cluster is necessary by some kind of forwarding in case these are separated networks.
Also the paths to the started binaries may be different, in case the two machines are not sharing the same /home with the cluster and this needs to be honored.
In case you are using a queuing system and want to route jobs to outside machines of the set up cluster: it's necessary to negotiate with the admin to allow jobs being scheduled thereto.
