The man page for mpirun (7.1.1, Sept 2004) has a discussion of I/O
redirection with many references to the "local node" or "the node that
invoked mpirun."
Should "the session of rank 0" be read in all those cases? Potentially
several sessions could be running on the node from which you ran mpirun,
and having them share stdin sounds impossible and sharing stdout
undesirable.
Then again, maybe rank 0 doesn't need to be on the same node as the one
used to execute mpirun, so my alternate formulation seems to have some
holes too.
