Thanks for your answer! I figured out that by first forking a "mpiexec 
-server" and subsequently forking "mpiexec --comm=none args" I can simulate 
the behavior. However, mpiexec does not let me choose the node the command is 
supposed to run on. We rely on some third-party software which produces 
errors if run simultaneously on an SMP system which cannot be prevented by 
using mpiexec.
