Have you tried the
--output-filename <filename>
switch to mpirun?
man mpirun may help.
If you are running under a resource manager,
such as Torque, the stdout may be retained in
the execution node until the war is over ...
well ... the job finishes.

Have you looked at "mpirun -h"? There are several options available for
redirecting output, including redirecting it to files by rank so it is
separated by application process.
In general, mpirun will send the output to stdout or stderr, based on
what your process does. The provided options just let you tag it, or
separate it by rank for convenience.

Hello!
Did you try to redirect also the error output? Maybe your application
write its output on stderr.
