As we're going to use MPICH2 in our cluster, we'd like to know what 
differences there are between the daemon-based and the daemon-less 
startups. Any problem of performance, for instance, or risk of conflict 
with the port settings concerning the daemon-based startup ?

Besides, as we already use MPICH1 to run MPI programs, will the choice 
of the startup method make any difference when we will migrate ?
